I had a 34' moderate displacement performance cruiser with a 35 hp and felt like that was just right. For your boat I wouldn't go any smaller than 40 hp. Max 45-46

winds. 40hp would be my minimum choice. A Beta 38 is you wanted to go that . But honestly the 4-107 (40hp) is a great choice. The rebuilds are and plentiful. Why not find a good rebuilder and go that . Probably under $6K. A new Beta 38 would probably put you back around $15K. Plus no mods.

Boat: 35 Ft. cutter, custom
size and displacement figures are a bit greater than mine. I use 40hp, (not a Perkins,) and find it the ticket for being able to back-an-fill with authority, and easily at low rpms with much quieter sound levels. I'll agree with Celestialsailor, nothing wrong with a Perkins, The newer rebuilds of 107s/108s are better than the old ones. Front end drives are better, and most important they don't leak , (at least I heard that).

Boat: (Cruiser Living On Dirt)
A rough of thumb for determining Horsepower Required for a Sailboat : one horsepower per 500 pounds ( ± 50lbs ) loaded.
Westerbeke Corporation suggests 2 hp for every 1,000 lb of displacement for coastal cruising, and 2.5 hp per 1,000 lb of displacement for . That would mean a 38 ft. sailboat with a displacement of 15,000 lb should have a 30 hp engine for coastal cruising and a 37.5 hp engine for . In your case: 15 Long Tons = 33600# Hence: 33. x 2 = 67.2 HP ~or~ 33.6 x 2.5 = 84 HP.
In their book "The Gougeon Brothers on Boat Construction" the authors suggest a good rule-of-thumb is 1 hp for every 500 lb of displacement... that would mean 38 ft. sailboat with a displacement of 15,000 lb should have a 30 hp engine. In your case 33 x 2 = 66 HP
Some people suggest 1 hp for every ft. of boat waterline length... that would mean a 38 ft sailboat with a waterline length of 30 ft should have a 30 hp engine. In your case 41 x1 = 41 HP
Some people suggest 3 - 5 hp (continuous rating) per long ton (to calculate the boat's weight in long tons divide the displacement by 2,240)... that would mean a boat with a displacement of 15,000 lb should have a 20 - 33 hp engine. For offshore conditions some people suggest the engine be larger than the size calculated for coastal cruising, possibly + 25%... so in this example the engine size would be increased to 25 - 41 hp respectively.
How do you measure horsepower? is a measurement of the ability to do a unit of in a specific time. It is calculated, not measured. Horsepower and watts (kilowatts are 1,000s of watts) are units of power. Power is calculated by measuring engine torque at a specific crankshaft and multiplying the 2 figures together.
Engine Horsepower/Torque Formulae
Horsepower = ( Torque in Lb/Ft x Crankshaft Speed in ) ÷ 5252
Power = Torque X RPM Torque = Power ÷ RPM RPM = Power ÷ Torque

in a 38' boat simply won't cut it.
Sure, you'll move the boat, but not at hull speed.
Engine hp is only one aspect, blade diameter, , number of blades, reduction, etc, etc, all play a part.
You really wanna learn?
Get the " Propellor Handbook" authored by Dave Gerr, will give you every tool you need to determine engine hp.
My suggestion would be nothing less than 40 hp....

, engine mounts, and are in the wrong places even if the compartment space allows for the new engine at all. There are strong reasons to either the existing engine or replace with an identical engine.
Consensus seems to be that your 40 HP is about right.

How Much Horsepower Do I Need for My Boat?
If you’ve been searching for a boat to purchase, or have reached the point at which you’d like to get a new engine, chances are you’ve asked the question, “How much horsepower do I need for my boat?” While the individual concerns may be different — wanting to make sure there’s enough horsepower or not too much horsepower — it’s a question many people who are interested in purchasing a new boat ask.
Sometimes, the follow-up question is, “Is it illegal to overpower a boat?” Whether you’ve been asking yourself one of these questions, or are just curious about how horsepower can affect the cost of fuel and insurance, we’ve gathered several pieces of information to educate you on horsepower. Through reading this information, you’ll be able to learn more about where it came from, how it’s calculated, how to determine the amount you need and the dangers that come with having too much.
What Is Boat Horsepower?
Horsepower is defined as a unit of power equal to 550 foot-pounds per second used to measure the power of an engine. Today, it applies to boat and auto engines, but its original use was to describe the power of a steam engine. In the late 1700s, a Scottish engineer named James Watt invented the first steam engine, which improved on a design pioneered by Thomas Newcomen in 1712 . It was a big deal. This new steam engine could do the same amount of work as the former Newcomen engine, but used only one-quarter of the fuel.
Unfortunately, comparing the steam engine to the Newcomen engine wasn’t effective marketing, as most of the population was still using horses for mechanical work. To market his new product to this audience, Watt knew he had to come up with a way to compare the work of horses to the work of his invention. Through his experiments, he determined one horse could do about 33,000 foot-pounds of work in one minute — meaning a horse could lift a 33,000-pound weight one foot in one minute. Therefore, he defined one horsepower as 33,000 foot-pounds of work per minute — or 550 foot-pounds per second.
There were a few flaws with this new measurement — the biggest being the assumption that a horse could continue to work at that consistent rate instead of tiring out. However, Watt didn’t let that fact bother him, and it didn’t bother his customers, either. Comparing the power of a horse to the power of a steam engine showed Watt’s steam engine could do the work of five horses, and it went on to become an integral part of the Industrial Revolution.
How Is Boat Horsepower Calculated?
The relevance of horsepower, the measurement of 550 foot-pounds per second, didn’t stop with the Industrial Revolution. The measurement of horsepower was converted into other units of measurement. For example, other experiments determined one horsepower equals 746 watts of energy. In other words, if you put a one-horsepower horse on a treadmill, it would be able to operate a generator producing 746 watts. Engineers also did calculations to relate horsepower to torque, which is especially important for boat engines.
Torque is easiest to explain through an example. Imagine you have a large socket wrench with a two-foot handle. You apply 50 pounds of force to that handle — when you do that, you’re applying a torque or turning force of a total of 100 pound-feet to the bold. Keep in mind, with that calculation, you could get the same result — 100 pound-feet of torque — by applying one pound of force to a socket wrench with a 100-foot handle, or by applying 100 pounds of force to a socket wrench with a one-foot handle.
In an engine, torque produces power — so being able to relate it to horsepower is critical. A device called a dynamometer applies a load on the engine and then measures the amount of power it produces to determine torque. Marine dynamometers are available, too — taking into consideration boat operation by simulating on-the-water operation. Once the torque has been determined, you’re able to convert torque to horsepower by multiplying torque by revolutions per minute (rpm) and dividing that product by 5,252. The divisor, 5,252, comes from a series of calculations that convert rpm to radians per second.
Through using a dynamometer, you’ll be able to see the horsepower versus rpm values for the engine, which is especially important for calculating peak horsepower. Engines will have a point in rpm at which the power available from the engine has reached its maximum. This is known as peak horsepower — it’s often documented as “___ HP at ____ rpm.”
Determining How Much Horsepower You Need
Once you understand the history of horsepower and how that’s connected to the calculation we use today, it’s natural to wonder how much horsepower your boat needs. There are several factors to take into consideration when you’re determining how much horsepower you need — the manufacturer’s limits and recommendations, boat horsepower-to-weight ratio, fuel efficiency, use of the boat, number of people on the boat and an industry rule of thumb. Here are some things to consider in each of these areas to help you answer the question, “How much horsepower do I need for my boat?”
Manufacturer Limits
The easiest place to start is with the boat’s capacity plate — or owner’s manual. In addition to giving you a maximum for passengers and cargo, the manufacturer will also spell out the absolute maximum boat horsepower. If you have a boat that was built before 1972, came from overseas or was home-built, you may not have a capacity plate, but boat owner’s manuals are often available online. If not, you can always contact the boat’s manufacturer to inquire about their limits and recommendations for your particular boat model .
Boat Horsepower-to-Weight Ratio
When you’re trying to determine the amount of horsepower you need, it’s essential to consider the weight of the boat. The boat horsepower-to-weight ratio is simple to calculate and can be expressed in horsepower per pound or pounds per horsepower.
Let’s say, for example, your boat weighs 5,000 pounds, and it has a 300-horsepower engine. Taking 5,000 divided by 300 gives you a result of 16.6 pounds per horsepower. Doing the opposite calculation — taking 300 divided by 5,000 — gives you a result of 0.06 horsepower per pound. The lower the number, the faster your boat will go. Remember the boat horsepower-to-weight ratio once you’ve decided on horsepower and are matching outboard to boat size. While one or two outboards may give you the same horsepower result, keep in mind additional weight will accompany each additional outboard motor.
Fuel Efficiency
The amount of horsepower you choose will impact your fuel efficiency. However, just because you have a higher-horsepower engine does not necessarily mean you’re going to use more fuel. According to Boating magazine , running your gas engine between 3,000 and 3,500 rpm and your diesel engine at three-quarters throttle is the sweet spot for fuel efficiency. If you’re running a lower horsepower engine at full throttle all the time, it’s going to use more gas than a higher horsepower with less throttle. Keep this fact in mind as you consider what horsepower to choose.
For those who prefer exact calculations, Boating magazine has provided some calculations you can use to run some of the numbers. You’ll be calculating the gallons of fuel that are burned per hour (GPH). To do this, you need to know gasoline weighs approximately 6.1 pounds per gallon, while diesel weighs about 7.2 pounds per gallon. You also need to know a well maintained four-stroke gasoline engine is estimated to burn about 0.5 pounds of fuel per horsepower per hour, while a similar diesel engine is estimated to burn 0.4 pounds of fuel per hour.
The equation is GPH = (specific fuel consumption x HP)/fuel specific weight. For example, if you want to determine the fuel consumption for a 300-horsepower gasoline engine, you would calculate (0.50 x 300)/ 6.1, giving you a result of 24.5 gallons per hour.
As with most decisions related to boating, the use of the boat is always a factor. Are you using the boat just to cruise with friends and family ? Or will you be pulling water skiers, wakeboarders and tubers ? The addition of pulling someone behind the boat — and the additional weight of storing watersport accessories — increase the need for power and are often a reason to consider adding horsepower to your boat.
Number of People
Once you’ve considered the use of your boat, the next question to ask is what the normal number of passengers for your boat will be. If it’s usually just you and a friend or a spouse, that weight is different than if you enjoy boating with several of your family members and friends.
Rule of Thumb
If you’re the type of person who doesn’t need precise calculations — or just doesn’t want to be bothered with them — the Boat Trader blog offers a rule of thumb to use when determining the amount of horsepower for your boat. The rule of thumb is based on weight alone, and says you should have between 40 and 25 pounds of weight for each horsepower.
For example, a 5,000-pound boat could have an engine with between 125 and 200 horsepower. Yes, the range is wide, but that’s because boats have a variety of different designs and handle differently. While this rule of thumb can be a helpful way to get a ballpark range, it still requires some guesswork when it comes to considering your boat handling.
Federal Regulations
Is it illegal to overpower a boat? According to the federal government, yes. There are a few different ways you can define overpowering a boat. The horsepower capacity section of the Code of Federal Regulations contains its definition of overpowering a boat.
There are two different ways the federal government uses to determine the maximum horsepower for any given boat — one is a computation, and the other is a performance test. The way that is used depends on the boat. For the majority, the computation method is best to use. You multiply your boat length by the transom width. Then you take that number, which is known as the “factor,” and match it to a horsepower capacity according to the Code of Federal Regulations Table 183.53 — Outboard Boat Horsepower Capacity, shown below.
Don’t forget to adjust the result based on remote steering, transom height and boat bottom.
The performance test method is for boats that are 13 feet or less in length, have remote wheel steering, have a maximum capacity of no more than two persons and at least a 19-inch transom height — or at least a 19-inch motorwell height and at least a 15-inch transom height. Through this method, there are very specific instructions for boat preparation addressing everything from motor mounting to fuel tanks to ensure consistency. There are equally as specific instructions for the conditions in which you can perform this test.
The first part of the performance test is the quick-turn test. Setting the throttle at a low maneuvering speed and facing straight ahead, you then turn the wheel 180 degrees in half a second or less and hold it there. If you can complete the 90-degree turn without losing control of the boat or reducing the throttle, your boat has passed the test. Repeat, increasing the turn in speed until you can no longer pass the test, or you reach the maximum throttle. The maximum horsepower the boat can use while still completing this test is defined as the maximum horsepower capacity, unless it is more than 40 horsepower, in which case, the maximum horsepower capacity is capped at 40.
The good news is, these rules are in place for boat manufacturers, so assuming your boat’s manufacturer is following the federal regulations, you can consider the maximum horsepower capacity listed on your boat meets the federal regulation for its maximum horsepower.
Insurance Considerations
The amount of horsepower your boat has will influence your boat insurance, which is another fact to consider. There are three main areas of insurance the amount of horsepower you choose for your boat will affect — overall coverage, premium cost and type of policy.
Overall Coverage
There is also a chance your insurance company will not cover a vessel that exceeds the boat manufacturer’s max horsepower. This is an extremely important factor, as it could affect your ability to get insurance coverage for your boat. If your boat is currently insured and you’re considering a motor upgrade, make sure you know your insurance company’s rules for horsepower limits. If you upgrade without abiding by these rules and notifying your insurance company, there’s a good chance they won’t cover any claim you file.
Premium Cost
While abiding by your insurance company’s rules for boat horsepower, it’s important to remember that doesn’t mean a change in horsepower won’t bring a change in your premium cost. As a rule of thumb, boats with higher horsepower will be more expensive to cover.
Type of Policy
In addition to solely considering the horsepower of the boat, the overall size of the vessel, which takes horsepower into account, may determine the type of boat insurance policy you need to get. For example, your homeowner’s or renter’s insurance policy will usually cover smaller powerboats with less than 25 horsepower. Boats that are larger and have more than 25 miles per hour horsepower almost always require a separate boat insurance policy.
Dangers of Overpowering Your Boat
Bigger and faster is not always better. Putting more horsepower behind your boat may seem like an innocent way to add some excitement to your boating experience, but it could cost you a significant amount of money in fines, lawsuits and damage to your boat. Here are a few examples of how your need for speed can get you in trouble when it comes to boat maximum horsepower.
Breaking the Law
Is it illegal to overpower a boat? In some cases, yes. There are federal laws in place to ensure the appropriate horsepower limits are listed on all boats. State and local laws regarding overpowering your boat vary. Make sure you know the state and local laws for the areas in which you’ll be boating. Otherwise, your excess horsepower may be putting you at risk for fines and other consequences.
Accident Lawsuits
Even if your state and local laws don’t address overpowering your boat, you’re still putting yourself at risk in other ways. If you’re in an accident, the fact that your boat’s horsepower is above and beyond the manufacturer’s recommendations will be in the accident report. While you may not have fines because of breaking state and local laws, you are very susceptible to being found negligent and the victim of a lawsuit, especially in a case where there are damages.
Too Much Weight
In recent years, more horsepower hasn’t always meant more weight. However, it is still true in some cases, and that additional weight is another component of high horsepower that can be dangerous. For example, the additional weight can make a self-draining cockpit useless, leading to flooding problems.
Boat Damage
Even with additional horsepower that doesn’t add weight to the boat, the additional speed applies pressure that can cause significant damage to your boat. Every part of your boat, from the transom to the bow, was created to withstand a certain amount of pressure and stress. If you decide to ignore the boat’s maximum horsepower and overpower it, you’re exposing every part of your boat to pressure above and beyond what it was designed to endure, risking significant damage to the hull of your boat.

What Size Outboard Motor for What Size Boat? (Boat Horsepower Chart)
Once you buy a boat you want, it is time to determine what size outboard motor for what size boat. As you can guess, there is no magic formula for estimating it precisely, but you can get rough numbers when you check relevant information.
You should start with a boat type , a maximum passenger number, and the equipment weight you plan to carry. Then, you can determine the maximum horsepower recommended for your vessel. Finally, think about 2-strokes and 4-stroke motor options, right propeller size , and fuel type. Sounds complicated? Let’s make it easier!
Table of Contents
Motor Size Matters
Things to consider when selecting an outboard boat engine, ways of pair an outboard motor with your boat size.
Yes, an engine size matters , and it is crucial to pair it with an adequate boat size to let it run smoothly.
Bigger motors with higher horsepower offer numerous benefits for comfortable boating, such as:
You can sail at high speed
A more sizable engine provides better handling, particularly when sailing at midrange speeds
It makes water sports cozier
You can count on better time maneuvering
Such an engine will give you better control and provide more secure sailing in harsh weather condition
Surprisingly, a motor with a bigger fuel tank uses less fuel
Downsides of a small engine
A too-small engine typically has difficulty powering a bigger boat so it will spend more fuel than a bigger model. Another problem is sailing with more passengers and equipment since extra load requires a motor with more horsepower.
Therefore, you should check the max HP a boat can handle before purchasing. That rating will show you a top weight it can carry, and you can risk uncomfortable and unsafe sailing, plus possible Coast Guard fines when exceeding it.

The vessel horsepower ranges from 2.5 to 1,000+ HP for contemporary outboard motors . You should pick out the most powerful one your boat can handle to provide smooth and comfy sailing.
Horsepower is used to measure the engine power. On average, your vessel will need 5 HP per 2,200 pounds (1,000 kg) its weight. Small boats shouldn’t use more than 75% to 80% of the max HP because of the possibility of rough waters and headwinds while sailing.
Only that way, you can count on enough thrust to drive as desire. You should think about a few things when determining how much horsepower your boat needs, including:
Manufacturer limits
Manufacturers’ recommendation always shows a maximum passengers number and cargo weight your boat can carry. You can also find the absolute max boat HP in the manual.
If you have a boat built after 1972, you can find a capacity plate with this information inside the transom. Older vessels, home-built models, and those made overseas typically don’t have that plate.
However, you can contact the manufacturer or look for their manuals online to discover limitations and recommendations for your boat.
Horsepower-to-weight ratio
The only way to precisely determine your boat’s necessary horsepower is to consider its weight. You can calculate this ratio in horsepower per pound or vice versa.
HP/boat weight = required horsepower per 1 pound (0.45 kg)
boat weight/HP = number of pounds per horsepower
Let’s say you have a boat weighing 5,000 pounds (2,268 kg) with an engine of 300 HP. The calculation will look like:
5,000 pounds / 300 HP = 16.6 pounds (7.5 kg) per horsepower
300 HP / 5,000 pounds = 0.06 HP per 1 pound (0.45 kg)
You should do the math to match the desired outboard engine with your boat size correctly. The result will show how fast your boat will go since its speed will be higher when these numbers are lower.
Horsepower your boat needs will also depend on its use. Any additional equipment weight or pulling water skiers behind the vessel increase the power it needs.
Number of passengers
In this case, the rule is simple. Your boat engine will work properly only when it carries 25 to 40 pounds (11.5 – 18 kg) per horsepower.
Once you have this information, you can check the boat weight and add the total weight of the passengers you plan to host on it. Then, you can effortlessly determine engine HP that matches your boat.
Fuel efficiency
As you can guess, the motor HP impacts the boat’s fuel efficiency, but that doesn’t mean a higher-horsepower engine necessarily consumes more fuel.
For instance, your motor with lower HP will use more gas at full throttle than the one with higher HP running with less throttle.
Engine type
Both 2-stroke and 4-stroke engines are good options. You should choose one or another, depending on the feature crucial for you.
The rule of thumb is that 2-stroke motors are lighter and less expensive, while 4-stroke models with the same power are quieter. However, these differences are diminishing nowadays.
Engine weight
One of the vital things is to match the outboard engine weight and boat size . That way, you will ensure sufficient power for the desired speed without jeopardizing safety and maneuverability.
Most 2 to 10 HP outboard engines weigh 35 to 90 pounds (16 – 41 kg). On the other hand, you should count on 100 to 160 pounds (45.5 – 72.5 kg) for a 20 to 30 HP motor. In this case, you can have a problem carrying a too heavy engine around.
Required speed
The rule of thumb is that your boat needs more power to reach a higher speed. The equation says that 1 HP can move 40 pounds (18 kg) of boat weight at 20 mph (32.2 km/h). According to that, you can calculate that your boat weighing 2,000 pounds (907 kg) needs 50 HP to reach the speed of 20 mph (32.2 km/h).
Federal regulations
In the US, it is illegal to overpower your boat. The Code of Federal Regulations clearly defines vessel overpowering, so you should check it before getting into a situation to break federal law.
You should know that your boat’s horsepower directly affects its insurance , and models with higher HP typically has higher premium costs. Keep in mind that the insurance company won’t cover a boat with an upgraded engine that exceeds the max HP recommended by the manufacturer.
The best way to properly pair an engine with a boat of a particular size is to determine its horsepower.
2 to 3.6 HP engine
These small, less than 40 pounds (18 kg) weight, 2-stroke outboard engines are an excellent option for portable boats, like:
Inflatable boats
Small pontoons
Small sailboats
They can push small boats at 5 to 9.5 mph (8 – 15 km/h), depending on weather conditions, current, as well as boat weight and design.
5 to 6 HP engine
This horsepower range is ideal for boats weighing 8 to 11.5 pounds (18 – 25 kg), including:
12 feet (3.65 m) long inflatable boats
Portable folding boats
Large canoes
8 to 12 feet (2.5 – 3.65 m) long inflatable and dinghy boats
Such an engine can propel your vessel with one person at 10 to 17.5 mph (16 – 28 km/h).
8 to 9.8 HP engine
You should pick out this small but powerful 11.5 to 20.5 pounds (25 – 45 kg) heavy outboard engine for your:
10 to 14 feet (3 – 4.5 m) long inflatable and aluminum boats
Large portable folding boat and sturdy canoe
Up to 14 feet (4.5 m) long light fiberglass boats
An outboard motor in this range is an excellent option for propelling a boat carrying a light load and two people at 9.5 to 17.5 mph (15 – 28 km/h).
15 to 25 HP engine
Although powerful, these 16.5 to 23.5 pounds (36 – 52 kg) heavy 4-stroke outboard engines are still in a small outboard HP class. They are an excellent choice for:
10 to 14 feet (3 – 4.5 m) long inflatable boat
12 to 16 feet (3.65 – 5 m) long Jon boat , fiberglass boat , and aluminum fishing boat
These smooth-running engines can propel most boats to 25 mph (40 km/h) when carrying several people and heavy loads.
Whatever boat type you have, you should buy the smallest possible outboard engine that can allow a max hull speed with 90% of the revolutions per minute. Unless you want a higher-speed boat , you can use your 20 HP engine for twenty years and get an excellent fuel economy.

The lower the “hp/lb” value, the faster the boat. For example, you have a 3,000-pound boat with a 200-horsepower outboard motor. A pound will correspond to 0.067 HP.
The weight boat is one of the variables to consider when finding the maximum horsepower. Calculating the ratio between horsepower and weight is straightforward. You only need your boat’s weight and its boat HP rating.

How Much Horsepower Does Your Boat Really Need?
By Alan Jones
September 4, 2023
This could be the shortest column in marine journalism history. “To determine how much horsepower to put on your boat’s transom, find the manufacturer’s maximum horsepower specification, and whatever number is listed there is the total power to install.” While that’s a good rule of thumb, there might be times when less is more.
Go for the Max?
One good reason to get the most power possible lies in durability and longevity. The greater the horsepower, the less an engine has to work to keep the boat on plane with greater efficiency. Let’s look at an example. The Pathfinder 2005 TRS with a Yamaha F115 will have to operate at 5,500 rpm to reach 36.5 mph and will get 3.5 mpg. Power the same boat with an F150 and it reaches 35 mph at 4,500 rpm and will get 3.9 mpg, according to the manufacturer-supplied performance data. This example also illustrates that the notion that less horsepower equals better fuel economy isn’t always true. Top speed is another reason to max out the ponies. More horsepower translates to a higher top speed. Sometimes the difference is dramatic. A Sundance FX19 flats boat with a Yamaha F90 will reach 41 mph, but it’s a 60 mph boat with an F150. Then there’s the resale value. If a buyer is looking at two identical boats and one has more power than the other, they will typically choose and often pay more for the more powerful boat.
Mo’ Power, Mo’ Money
Often, taking even a small leap in power can cost big bucks. The standard engine on the Blackfin 232DC is the Mercury 225XL FourStroke, but bumping it just 25 hp to the Mercury 250XL will cost $4,921 more. In this case, the big jump comes by moving from the 3.4L family of V-6 engines to a 4.6L V-8 for the 250. When reviewing the build-a-boat feature found on most manufacturers’ websites, compare the cost with different engines and look for the sweet spot where the least amount of money buys the biggest jump in horsepower. Often, the max-power option is an exotic engine that comes with a larger-than-proportional price tag.

Less Power Equals Less Weight?
Sometimes, adding more horsepower changes the weight drastically, but an increase in horsepower often adds no weight because it is done via programming the engine’s electronic control unit. For years, Mercury’s supercharged Verados all shared the same 2.6L inline-six-cylinder block, even though the horsepower could range from 200 to 400, with a weight difference of just 38 pounds.
In the case of the Mercury 225XL V-6 versus the 250XL V-8, the weight difference is 52 pounds, which might not seem like much but could be significant on a small flats boat. Using multiple engines just exacerbates the difference.
Moving to the largest engine can make a huge difference. Mercury’s new Verado 600 is a 7.6L V-12 behemoth with a host of technological advances, but it also weighs 1,260 pounds. Yamaha’s XTO Offshore 450 V-8 weighs 988 pounds. In comparison, the Mercury 450R weighs just 689 pounds. Although more weight can cause slower hole-shot times, often this is counterbalanced by the additional horsepower and the larger prop that a higher-horsepower engine can swing. Need an example? Take a look at the Mercury Verado 600 V-12 that turns a massive 18-inch-diameter prop.
Horsepower needs also change if only one or two people routinely use the boat. If you typically invite a crowd of friends to go fishing, powering up to the max might make more sense. Otherwise, the boat can be sluggish and slow to respond to the throttle.
Variables Matter
If a boat weighs more, it’s probably going to need more power, but factors such as the hull design also matter. A Carolina Skiff 21 SWS is a 21-footer that features a relatively flat hull bottom, weighs 2,351 pounds, and has a maximum horsepower rating of 150. The Regulator 23 has a steep 24-degree transom deadrise to help it slice through ocean waves and weighs 6,700 pounds with a single outboard. The smallest outboard you can buy it with has 300 hp.
If a boat has a transom deadrise of 20 degrees or greater and is run in waters that can get rough, err on the side of more power. During situations like running through a ripping inlet, having crisp throttle response is often needed to safely transit out or return.
If you’re not sure about how much power to choose, talking to a local dealer is a good idea. They have the experience with and information on the models they sell that can help you make the best possible decision when it comes to the question of, “How much horsepower do I really need?”

Boat Test: 2024 Bass Cat Jaguar STS
By John Tiger
July 11, 2024
The 100 mph Jaguar STS and its 500R Mercury Racing motor isn’t for everyone. In fact, Bass Cat president Rick Pierce personally qualifies each potential Jaguar STS buyer. How? Among other things, he’s looking for a buyer likely to have supercars such as Ferraris, McLarens or Porsches. STS stands for Soft-Touch Special hull. It has a wide footprint and a strategically designed and applied center pad and lifting strakes. The STS hull is not new, but with the arrival of Mercury’s 500R, Pierce had to dial it in for high power. We tested on a blustery day, with windblown lake chop topping 2 feet. This limited our results to 98.5 mph, but Pierce showed me saved GPS recordings of 103-plus mph.
Interior and Accessories
As a fishing platform, the Jaguar STS has a new console sculpted to carry a flush-mounted 12-inch multifunction display networked to show full engine data, as well as GPS position and charts. Tilt hydraulic steering keeps the Mercury 500R in line. A two-tier center console between the seats provides a step to the aft deck while housing a glove box and a cooler. Sturdy, stylish billet grab bars are within easy reach for pilot and navigator.
The large bow panel flush-mounts two stacked MFDs without external brackets, or easily accepts three with a Ballzout bracket. A main power switch, quick trolling-motor disconnect, and digital voltmeter are housed in a separate panel in the nose. All lids are supported with new soft-closure seals and “Slam” latches. The trolling-motor pedal position can be customized by fore or aft placement of a removable block. Built-in rod ramps in port and starboard gunwales secure rods on deck, and a large center locker for tackle boxes is flanked by a rod-storage box to port and a general storage locker to starboard. A center step up to the foredeck offers a second cooler.
Unique triangular livewells on the aft deck are engineered to prevent sloshing and to maintain balance at the centerline. Small triangular day-storage boxes are located behind the livewells, with larger dry-storage compartments on each side. Trays lift out to add access to pumps, screens and rigging already accessible beneath large removable hatches at the transom.

How We Tested
Engine: Mercury 500R FourStroke 500 hp
Drive/Prop: Outboard/Mercury Bravo I FS 15.25″ x 32″ 4-blade stainless steel
Sleek console redesign for 2024 adds a more aggressive performance look to the deck while focusing the pilot’s full attention forward, where it should be.
Siren Marine remote monitoring and tracking system helps owners keep an eye on this valuable fiberglass.
Patented Lift Latches (slang: “Slam Latches”) make closing hatch lids easy and secure; no fiddling and fumbling anymore—just load and slam to close, and push the button to open. Slick!
While Rick Pierce prefers a hand throttle for steadier control for neophytes, we’d rather see a foot pedal for optimal performance driving.
Toughest Competitor
Bass Cat makes it tough to find a close competitor. We are unaware of any 22-footers that can carry 500 hp, but Bullet’s 21XRS (around $150,000) is as close as they come. It measures 21 feet, 10 inches with a 7-foot-7-inch beam, and while Bullet hasn’t rigged one with a 500R, there are many on the water hitting the 90 mph range with a 300 hp outboard. How? The Bullet tips the scales at just over 2,200 pounds.
Boat to launch new smart ring in India at one-tenth the price of Samsung Galaxy Ring
Boat Smart Ring Active will soon launch in India at an introductory price. It will feature a stainless steel body and support health monitoring features.
Boat Smart Ring Active India price and availability
The Boat Smart Ring Active will be available in three color options and five sizes. It is set to launch in India on July 20 and can be pre-booked starting from July 18 on Amazon, Flipkart, and the official Boat India website. The special launch price for the product is confirmed to be Rs. 2,999, and it will also come with a portable magnetic charging case. The Samsung Galaxy Ring costs approxiametly Rs 34,000 in India.
Boat Smart Ring Active features
The Boat Smart Ring Active will feature a stainless steel body and has been teased to support auto health monitoring. This includes tracking heart rate, blood oxygen (SpO2), sleep, and stress levels through multiple sensors.
The existing Boat Smart Ring model enables navigation in short-form video apps, music playback, and camera controls. It offers up to seven days of battery life, has a 5ATM water resistance rating, and can be used to activate SOS calls.
Meanwhile, the Galaxy Ring is available in nine sizes , ranging from five to 13, and comes with a sizing kit to help you choose the right fit from these options. It has 8MB of memory and is equipped with a PPG (Photoplethysmography) sensor to detect irregular heart rhythms. Additionally, it includes a temperature sensor and accelerometer to provide wearers with insights into their well-being. The Galaxy Ring is compatible with the Samsung Health app.

How to Calculate Outboard Motor Size for Sailboats
To get the right amount of horsepower needed to efficiently propel a sailboat, divide the displacement of the boat (in lb) by 550. You need approximately 1 HP per 550 lb of displacement or 4 HP per 2200 lb. Most sailboats don't need a motor with more than 30 HP. In this article, I'm talking about small outboard engines for sailboats.
