The Best Outboard Motor for a Sailboat

The technology of sailing has remained mostly unchanged for centuries. Since learning to harness the power of wind, sailors have been transiting the world’s oceans, expanding trade routes and exploring new cultures. Although nothing more than a renewable natural resource and a single sail is needed to move a sailboat along the water, there are times when it’s important (and in our modern age, convenient) to leverage off a motor to get you where you need to go.

Like any unique piece of equipment in the world of sailing, outboard motors come in a variety of sizes with features and options to fit any owner’s needs. But of course, one size doesn’t fit all. Every boat is different – even those that come off the production line at the same time – and every owner is looking for something specific when it comes to their sailboat. From the purpose of owning the boat (blue water sailing vs. racing) to the location and impact on maintenance (cold weather vs. tropical weather), an outboard motor is just one of the many elements that will define a sailboat’s function and performance.

Whether you’re a new owner, or a veteran sailor, it’s important to know the basic components of any outboard motor . You should also have an idea of what you want your outboard motor to do for your size and model sailboat.

Outboard Motor Size

A larger boat doesn’t necessarily mean a larger motor. Although there are different ratings for different classes of boats, a small power plant can be more effective than a larger one. Conversely, an outboard motor can easily overpower a small boat and create unsafe conditions at high speeds. Guidelines and requirements differ between motorboats and sailboats. And while there is some overlap, these considerations apply directly to sailboats.

Engine power has to do with how much water a boat displaces. For sailboats, smaller is better. If you’re a bit of a math geek, the exact formula is 4 horsepower for every 2200lb of weight. Coupled with a propeller size, which can be determined using a propeller calculator , you’ll get a rough estimate to use as a guideline to start shopping. This is a good first step, since size is essentially a fixed variable. Though it’s worth noting for those who are buying a sailboat directly from the manufacturer, that actual weight will increase after delivery – once all other rigging and outfitting has been completed.

Physical size of your outboard motor is an important consideration and is directly related to the design of your sailboat. An outboard motor is made up of three parts from top to bottom:

• The Powerhead – Houses the engine. The bulbous part of the motor.
• The Midsection – Houses the exhaust system. Varies in length and design.
• The Lower Unit – Propellers attach to the gearbox. Submerged when operational.

Shaft length is an important design element and should be considered when purchasing a motor. A shaft that is too short will obviously prevent the propeller from being submerged in water, while a shaft that is too long will extend the propellers too far. Not only will it decrease the efficiency of your engine, it will create unnecessary drag. Know your transom length when looking at different models.

When an outboard motor is not being used, it should be stowed in its upright position. Some of the larger motors have an automated switch that will raise it out of the water, but some must be secured manually. Make sure everyone who sails with you is capable of lifting and securing the motor out of the water in case of an emergency.

Outboard Motor Power

Any kind of motor installed on a sailboat (inboard or outboard) should be viewed as a tool to help with maneuvering. Although there are some very skilled sailors out there who can sail into their slip without the aid of a motor, many harbors have restrictions that either don’t allow for the use of full sails, or there simply isn’t enough room to maneuver. A motor with both forward and reverse gears helps tremendously with docking.

While there is no exact correlation between boat length and total weight, the following is a rough guideline:

• 1-4 HP for boats up to 20’ (approximately 1000-2000lbs)
• 4-18 HP for boats between 20-30’ (approximately 2,000-10,000lbs)
• 18-34 HP for boats between 30-40’ (10,000lbs or more)

There are some things to consider when deciding how much horsepower you need or want. Location and the type of conditions you expect you’ll be sailing in is one of the biggest factors. Heavy seas and high winds typically associated with open ocean sailing will put more strain on your engine, and in some cases overpower it, whereas an engine that is heavier than needed will add unnecessary weight when racing. If you plan on motoring for long distances, consider purchasing an engine that will stand up to a lot of use.

Less HP is required for:

• Boat Design – Single hull boats made out of fiberglass require less power.
• 2-Stroke Engines – This is due to an overall lighter weight engine and higher torque.
• Diesel Engines – Diesel delivers more torque because the rate of compression is greater.
• Bigger Propellers – More surface area means more water displacement.
• Location – Motoring on lakes and rivers requires less power than open ocean.
• Distance – A smaller engine is suitable for shorter distances.

More HP is required for:

• Boat Design – Catamarans and heavier boats (regardless of size) require more power.
• 4-Stroke Engine – Engine weight and an extra step of compression yields less power.
• Gas Engines – The rate of compression for gas engines is much lower than diesel.
• Smaller Propeller – A smaller propeller displaces less water.
• Location – Open ocean, with tides and currents, will strain a smaller engine.
• Distance – Cover more distance when wind conditions are poor requires a larger engine.

Outboard Motor Cost

There is no way to quantify how much you will pay for any given motor. But there are several costs associated with owning an outboard motor that are definitely worth considering when making your purchase.

Certainly, a lager, more-powerful engine is going to be costlier than a smaller engine with lower horsepower. But as mentioned earlier, size is not necessarily a guarantee of performance and efficiency. At the same time, there’s only so much you can get out of an engine before you exceed its capability. Larger engines tend to help with resale value should you choose to sell your boat at some point, but a boat outfitted with right motor to begin with will always perform better than a motor that’s large just for the sake of it.

Factor in maintenance costs and fuel when looking at models. You want to run your engine at around 90% of its max RPMs to balance proper fuel usage and with wear and tear. Making a few calls to marine mechanics to inquire about an engine you’re interested in will give you a lot of information a sales person won’t be able to give you. The good news about outboard motors is that most of them are portable, which means you won’t have the added cost of either paying a mechanic to come to you, or having to get your boat to the yard, which usually requires help from a very good friend willing to spend all day driving and sailing back and forth.

Owning a boat requires constant care and maintenance, so a little knowledge goes a long way. While an outboard motor is not required for sailing, it’s a convenient addition that can greatly increase your enjoyment out on the water. Being patient and spending time researching engines will not only help you make the correct purchase but will help you take advantage of a great deal when it presents itself. Whether you sail the Caribbean, or race off the coast of California in a catamaran, there is an outboard motor that’s just right for you.

Lightweight and Small Outboard Motors for Sailboats

• By Ed Sherman
• Updated: April 22, 2019

When you’re facing strong winds and you need to get somewhere fast, it’s time to break out a small outboard such as an aluminum genny. A dependable outboard that has enough horsepower to get you to the racecourse and back, yet is light enough not to be a drag on your race results, is invaluable. Most racing sailors don’t need as much horsepower as they might think.

An eight-horsepower outboard, for example, will push a 30-foot, 6,000-pound boat along at 6.5 knots. Anything bigger will weigh more than 90 pounds and isn’t suitable for lifting on and off the stern. Here’s our roundup of some of the best outboard motors for sailboats, and some help in deciphering what’s right for your boat.

We focus our attention on engines available under nine different brand names. Two of the best-known names, Johnson and Evinrude, have dropped out of the small-engine end of the market as part of parent company Bombardier Corporation’s restructuring of these two companies. Currently they’re advertising the availability of six- and eight-horsepower four-stroke models in 2003. Another dropout in the mini-engine market is Suzuki. Their smallest two-stroke is a five-horsepower unit and in the four-stroke configuration, a 9.9 horsepower. Brand and corporate shuffling aside, of particular interest is whether the companies that are building nine horsepower- and-below engines have incorporated four-stroke technology into the lower horsepower range, since it’s now beginning to dominate the mid-sized and larger outboard engine market. The answer to that is yes, to a point.

Two or Four Stroke Outboards for Sailboats

Outboards are either two or four-stroke engines, and the four-strokes have definitely gained favor in recent years for several reasons: they’re quiet, they use much less fuel, and they run more cleanly. Since no oil is mixed with the fuel, the classic two-cycle smokescreen isn’t a factor. In a four-stroke, the piston reciprocates inside the cylinder four times for each power stroke (that is, each time fuel combusts). Rather than opening ports cut into the sides of the cylinder, intake and exhaust valves controlled by a camshaft allow a fuel/air mix to enter the combustion chamber with the suction created by the piston as it moves inward in its cylinder. Exhaust gases are forced out of the cylinder as the piston moves outward.

By carefully designing the camshaft, engineers minimize the amount of time that the intake and exhaust valves are both open, considerably reducing the amount of unburned fuel that exits with the exhaust stream. The end result? Fewer emissions and greater economy.

But they do have at least one distinct disadvantage for the racing sailor, and that’s weight. For example, four-stroke engines in the five-horsepower category are about 20 percent heavier than comparable two-stroke engines of the same horsepower. The good news, however, is that only amounts to between 10 and 15 pounds, depending upon the engine. Four-stroke engines cost more, also, but the improved technology may be well worth it.

If you’re totally weight and price conscious, you’ll want a two-stroke engine. But, if you think you can lose the weight elsewhere, a clean, quiet four-stroke without the hassle of mixing fuel could be the answer. In fact, Mercury/ Mariner’s newest six-horse four-stroke engines are actually 18 pounds lighter than their older two-stroke equivalents–a testament to the benefits of improved design and technology.

Environmental regulations are pushing manufacturers towards four-strokes as well. Four-strokes meet emission control standards, and US Environmental Protection Agency regulations mandate that new outboard and personal watercraft engines reduce engine hydrocarbon emissions by 75 percent by 2006. Environmentally conscious sailors should look for either a C.A.R.B. (California Air Resources Board) “very-low” or “ultra-low” designator, or a specification indicating 2006 EPA compliance.

How Much Horsepower Do You Need?

The amount of power you’ll need depends on several key factors. The first consideration is the weight of your boat. The second is the boat’s wetted surface. Full-keel boats not only weigh more but also have more surface area to push through the water. My rule of thumb here is to start with a two-horsepower engine for small centerboard and keelboats less than 1,000 pounds, and add one horsepower for every 1,000 pounds of displacement. For more exact, albeit complex formulae, I suggest The Propeller Handbook by Dave Gerr (McGraw-Hill 2001).

Compare your boat’s dimensions against what existing classes have found to work; for example, a Melges 24 at 1,650 pounds is typically rigged with a three-horsepower short-shaft engine, while a J/80 at 2,900 pounds can still squeak by with a long-shaft, three-horsepower engine. A 1,790 pound J/22, on the other hand, typically uses a four-horsepower long-shaft engine. On the larger end of boats using outboards, you’ll find the outboard version of the J/29, at 6,000 pounds, requires a 7.5-horsepower long-shaft engine.

If you are intending to do some cruising, or even long deliveries to regattas, an option that’s available on some engines is a high-thrust propeller. On larger boats, this option can save weight over a bigger engine and really make a difference when trying to punch through a strong tide or headwind. High-thrust props cost more and are less fuel efficient–but they can save weight and give you more power.

Once you’ve determined how big an engine you’ll need, the next step is to begin comparing features in the given horsepower range you’ve selected. There are nine manufacturers included in our roundup, but some of their brands are identical products with different labeling. In the smaller sizes, the Mercury and Mariner brands are identical. As for the Nissan and Tohatsu engines, Tohatsu builds them all. Yamaha, Suzuki, and Honda all offer competitive products as well, but they’re all independent brands.

What to Look For in Lightweight Outboard Motors

In the small engine sizes, specific features to look for can be reduced to several key items. For some, having an integral fuel tank will be important. The smallest engines have integral tanks that hold only a quart or two of fuel–good enough for an hour or two of operation. No manufacturer lists fuel consumption because the size boat the engine is pushing and the wind and wave conditions vary widely. Compare the size of the tanks, and whether you can attach a remote tank for longer trips. The extra weight and space of a separate fuel tank will be a burden on smaller ultra-light boats.

The availability of long- and short-shaft versions in the horsepower size you need is also important. Honda for example offers 20 and 25-inch transom height (long or short shaft) right down to their smallest BF2 (two-horsepower) model. Mercury and Mariner only offer a 15-inch short-shaft version on their 3.3- and 2.5-horsepower engines. Shaft length is measured from the top of the bracket to the tip of the shaft–make sure your shaft is long enough to position the propeller and cooling water intake deep enough below the waterline to avoid cavitation when the boat pitches through waves.

Other specifications that are worth comparing are whether the engine is equipped with a simple forward and neutral gearshift or if the unit has a full functioning forward-neutral-reverse gear unit. If you’re going to be doing long deliveries to regattas, or in the larger sizes for a racer/cruiser configuration, consider whether or not a charging system is part of the engine package, and if so, it’s output. Will it be adequate to keep your battery recharged and power things like a tiller pilot and running lights? Also, on the larger engines check to see if electric starting is available, or offered as a standard feature. Having it can be the difference between pain and pleasure.

If you are racing in a strict one-design group, check any class rules that apply to outboard engines. Issues related to brackets, storage of the engine and/or alternative weight might be issues, so be sure to check with your class before making any final decision.

Your boats speed and handling depend directly on the outboard engine used to power it. Additionally, an outboard engine affects both safety and performance. Knowing what to ask when buying an engine from Yamaha, Mercury, Honda, or another manufacturer is critical.

An outboard motor is attached to the transom and hangs outside the back of the vessel so that the propeller is submerged. From there, it can be tilted forward on a pivot to lift the entire motor out of the water. A handle is attached to the top of the outboard motor so that you can use the direction of the propeller to steer the boat.

You should always get an outboard motor with the maximum horsepower your boat is rated for. Remember that horsepower equals performance. How high you can go depends on what kind of boat you have. For example, inflatable boats average between 9 and 25 HP, while pontoon vessels can go as high as 300 HP, depending on the model.

Older outboard motors are generally carburetor-driven and require a special oil to be premixed with the gas before its added to the tank. The oil provides lubrication as the fuel is used. Contemporary outboard motors with carburetors keep the oil separate, offering a cleaner exhaust.

In electronic fuel injection, a computer introduces a precise amount of fuel into the outboards air intake manifold. This controls the amount of fuel/air vapor entering the chamber, enhances engine power, and lessens pollution. With Direct Injection, also called Electronic Direct Fuel Injection, an exact amount of fuel is injected directly into the cylinder under high pressure. Only air is introduced through the outboards air intake.

A two-stroke, or two-cycle, outboard motor completes the power cycle with two strokes. The first draws air and fuel into the combustion chamber and creates compression. The second stroke ignites and exhausts. The two-stroke outboard engine is lighter, with more power for the same size, and offers better acceleration. It is favored for smaller, lighter boats, like dinghies.

A four-stroke, or four-cycle, engine uses four strokes to complete the cycle. The first draws fuel and air into the combustion chamber. The second compresses the fuel-air mixture. The third ignites the fuel-air mixture and generates power. The fourth and final stroke expels the exhaust. Four-stroke engines, although large and heavy, offer more torque and better fuel economy. It is a good choice for bigger, heavier boats.

Everything We Know About Yamaha's Hydrogen Outboard Engine

Ben Speciale, President of Yamaha's U.S. Marine Business Unit, confirmed Yamaha's commitment to attaining carbon neutrality of its operations by 2035 and its products by 2050. Speciale went on to say, "We believe hydrogen is a viable method of achieving these goals," at the unveiling of the Yamaha Motor Corporation, U.S.A. hydrogen-powered outboard engine in Miami, Florida, on February 14, 2024. With that announcement, Yamaha joins other companies working on hydrogen-powered vehicles .

Yamaha's hydrogen-powered outboard engine, dubbed the H2, is part of a prototype project announced in December of 2023 that includes fuel system engineering by Roush CleanTech, part of the same organization as Roush Racing, and a modified 26-foot boat built by Regulator Marine. Joan Maxwell, President of Regulator Marine, said the project is important for testing hydrogen as an outboard engine fuel source, explaining, "If we don't look for a new source, we won't find a new source."

The H2's hydrogen fuel system requires large hydrogen storage tanks, one of the cons associated with hydrogen-powered vehicles , which the boat's hull must accommodate. Maxwell admits the Hydrogen tanks are larger than she envisioned at first, occupying valuable space in the prototype hull that typically houses fish boxes and marine head facilities.

Roush's Matt Van Benschoten, Vice President of Advance Engineering, said, "Yamaha is trying to determine if hydrogen can successfully be used in this market." In support of the prototype, scheduled to begin testing during the summer of 2024, Roush is providing the design and integration of the hydrogen fuel system, as well as safety analysis.

Yamaha's H2 outboard engine

Yamaha's H2 hydrogen-powered outboard engine uses hydrogen instead of gasoline in its combustion chambers. While this technology is a departure from the systems found in hydrogen fuel-cell vehicles (HFCV) driving the streets of California, it's more like the internal combustion engine we're accustomed to rather than battery electric vehicle (BEV) power.

The H2 hydrogen outboard is a derivative of Yamaha's XTO Offshore outboard engines. The XTO Offshore outboard's 5.6-liter V8 gasoline-engine produces up to 450 horsepower, making it one of the most powerful Yamaha boat motors ever made . Hydrogen's low volumetric energy density means the H2 will produce slightly less horsepower than the XTO Offshore using the same 5.6-liter displacement.

Examples from Cummins, a reputable diesel engine innovator, demonstrate the loss of power by comparing horsepower ratings of two 6.7-liter internal combustion engines, one gasoline powered and the other using hydrogen. The gasoline-powered Cummins 6.7-liter is rated at up to 325 horsepower compared to the hydrogen version with its 290-horsepower rating.

If the 10-percent power loss of the Cummins example is seen in the H2 outboard, it could still produce in excess of 400 horsepower. That output would put it in the ranks as one of the most powerful outboard boat engines available and with zero carbon emissions.
