How to Find the Best Outboard Motor for Your Budget

Latest posts by Juan Alexander (see all)

    Boats come in different sizes and models, but all rely on an outboard to deliver speed and seamless travel. The outboard engines keep evolving to meet different boat needs over time, with some falling out of favor and newer models pushing the boundaries of what seemed to be impossible. 

    The outboard motor engines’ changes are so far-reaching that we no longer discuss whether you need a two-stroke engine or a four-stroke engine. The changes in the outboard motor engines have created fundamental differences that make it necessary to analyze each engine on its specs to come out with a clear favorite given their features.

    Among the changes, we’ve noticed the emergence of low fuel consumption and alternative fuel outboards, joystick steering, and the increase in horsepower, with some models pushing the envelope beyond the 400 limits.

    The difference in Water Engines

    There are mainly three types of engines used to powerboats over water, inboards, outboards, and the sterndrive. The engines are classified depending on their location of the boat or whether they are involved in both propulsion and steering.

    An outboard motor is a self-contained unit used to both power and steers the boat installed on the outside of the boat on the transom. You often have to move the entire engine to steer the boat; it is achieved using the tiller on small boats or a steering wheel on large boats.

    Inboard engines are placed under the deck and are out of sight. They are modified for use underwater by powering a drive shaft connected to a prop. D-Drive inboards are located under the center of the boat, while V-Drive D-drive is situated under the transom.

    The sterndrive is a combination of both the inboard and outboard hence referred to as inboard/outboards (I/O). The engine is usually at the back of the boat while the drive unit is fixed below the swim deck.

    Why Do You Need an Outboard Motor?

    the Best Outboard Motor

    Sterndrives and inboards seem to be clear winners when you need some water play as they outboard google up the transom space you could use for swimming.

    But as far as it goes, outboard has a few advantages over stern drives and inboards, and You will be surprised how much you miss one when you decide based on single merit. Here are the benefits of an Inboard:

    Performance to weight ratio

    Outboards used to have low performance compared to stern drives, but the emergence of high power outboard motors has evened the odds while putting outboards at par with sterndrives.

    Both sterndrives and outboards have different horsepower options, so in determining performance, you do not rely on the engine’s raw power rather the performance to weight ratio.

    When comparing a 400HP outboard and a 400HP sterndrive, you realize that the sterndrive weighs hundreds of pounds more than an outboard motor. When it comes to performance and handling, the lighter outboard is better as it goes out faster.

    Fuel efficiency

    The extra pound that a stern drive adds to more weight the water engine has to carry on a cruise. As the weight increases, it leads to more fuel consumption in gallons per hour. When minimizing fuel consumption on a motor outboard, it is better to choose a modern four-stroke outboard that is often more fuel-efficient compared to a two-stroke engine outboard.

    The outboard tends to have higher RPMs at cruising speeds, yet they still truce the stern drives at fuel efficiency. The oil efficiency is more evident when you use your boat for frequent rides.


    Sterndrive engines use a marinized automotive block that makes them extremely sensitive to cold. Due to this risk, the engines require an extensive winterization process to eliminate the risks of freezing. Combining these two factors implies shorter boating seasons.

    Winterization must only be done by a qualified marine mechanic since it is highly technical and complicated. The process means that you need more preparations and have your boat ready for spring. In addition to winterization, you have to always remain cautious when using sterndrive engines by protecting them from freezing temperatures. That often means cold nights force you to take your boat earlier than usual.

    In contrast, outboard engines have a straightforward winterization process which means most owners can perform the winterization process efficiently. Simple winterization means that you can start cruising immediately in spring.

    The ability to tilt the outboard means you can drain the water to make the water engine less prone to freezing, allowing you to extend the boating season.


    Only outboards can be tilted due to their location on the boat. Sterndrive engines are located under the boat, making it impossible to tilt them. Due to the outboard motor tilting, you can shift the propeller or the entire engine and drive it out of the water.

    Tilting enables you to navigate shallow waters as you can lift the engine to reduce damage. You can also protect your outboard from saltwater corrosion and marine growth by tilting the outboard when it is not in use. As we noted earlier, tilting enables you to drain water from the water engine to keep the engine from freezing overnight, options that are not possible with inboards and stern board.


    Outboards, inboards, and sterndrives have completely different designs, which means their buying price is different.

    It is worth noting that all the water engines used to have competitive prices but the Environmental Protection Agency (EPA) made rules that force the sterndrive to have catalytic converters like car engines which caused their prices to shoot while the outboard motor remained the same.

    What Factors Should You Consider When Buying An Outboard Motor?

    Best Outboard Motor

    There are different types of outboard motors, and the choice of what to buy has to be made in such a way that is systematic and gives the most value to the user. Here are the most important characteristics to consider when purchasing an outboard motor:

    Fuel Efficiency

    Outboards depend on fuel to give you good cruises, an outboard that consumes more than its fair share of fuel is bound to get you into trouble. When all other factors are equal, a four-cylinder engine consumes less fuel than a six-cylinder engine.

    The heavier the outboard motor, the more they contribute to the fuel consumption. The fuel consumption also has to be relative to the size and the weight of the boat. Any fuel saving will quickly go out the window when you overburden a four-cylinder engine with a huge boat.

    The outboard has to work extremely hard and requires more fuel making a six-cylinder outboard more effective.

    The Boat’s Hull

    Big outboard engines have more power than their much smaller counterparts; however, they need more space at the hull and are more suited for large boats. Older boat models are designed for the smaller two-stroke engine; hence overburden with a four-stroke engine might be counterproductive.

    A rule of thumb is always to stay twenty to forty pounds of the intended motor weight when choosing a four-stroke engine. You have to keep in mind that lighter outboards create less draft; hence work best when planning to fish in shallow water.


    There is a lot of craze about the horsepower as higher horsepower outboard motor engine models get released each year. You have to keep in mind, however, that a high horsepower engine is not necessarily good; hence you need to know your cruising speed, boat capacity, and fuel consumption of the outboard and appropriate boat size.

    Small boats such as sailboats, dinghies, or canoes should never exceed 10 horsepower. In contrast, long and light boats, say 10 to 15 feet made from aluminum or fiberglass, need moderate horsepower to go up to 20 horsepower.

    Boats ranging from 15 to 25 feet need a bit more power, such as 75 to 90 horsepower, for recreational activities around the shore. However, you can aim for significant horsepower up to 300 HP when you need to travel further at high speed.

    The same goes for boats over 25 feet long that have an optimum horsepower of 200 to 300, but extra speed and power imply exceeding these limits.

    Fuel Injection

    Best Outboard Motor

    The fuel injection is how fuel is introduced into the combustible units of the outboard engine. There are three main fuel injections with different efficiencies. A direct fuel injection deposits the fuel directly into the engine cylinders for efficient and reliable performance.

    Electronic fuel injection relies on an electric system to control fuel and airflow into the system. The carbureted fuel injection system is the least expensive to buy but costly in the long run.

    Instead of a system controlling air and fuel into the engine cylinders, a gadget controls fuel and airflow into the cylinder. The carbureted injections last when it comes to fuel efficiency.

    The Price

    After considering all the other properties, it is safe to ensure that your budget fits the desired outboard. Luckily there are numerous outboards with different prices that have relatively the same specs.  It would be best if you were not too economical to give your boat an outboard with either low power or a short lifespan. However, you must ensure that the cash you pay is reasonable.

    Alternative fuels

    Outboards do not use the same kind of fuel, and you can consider the relative advantages of the fuel types when purchasing the board. Most two-stroke outboard engines use a mixture of the oil-fuel mixture. Those that use an ethanol mixture have the effect of the ethanol dissolving horse and causing leakage.

    The LPG fuel outboards cause less environmental impact though they are still considered exotic and less viable. The electric outboard motor is coming of age, having high horsepower but going for shorter periods.


    A side-by-side comparison of a six-cylinder motor and a four-cylinder motor with the same horsepower reveals that a six-cylinder model has more significant displacement. The greater displacement means a six-cylinder will consistently outperform a four-cylinder.

    The six-cylinder has higher and a broad range RPMs; hence it is a top priority; you should choose a six-cylinder motor all the time.

    7 Best Outboard Motors

    There is a myriad of factors to be considered when picking an outboard. Getting an outboard that checks all the right boxes takes lots of research and testing to ensure you get a high-quality product fit for your specific kind of boat.

    Here is a complete list of the best outboard motor engines that would perform optimally in most conditions. The factors included in determining the best outboards include the level of ingenuity, the ability to withstand varying conditions, and raw power.

    How to maintain an Outboard Engine

    Outboards play a crucial role in making sure you can enjoy your day in the water rather than struggling to row your boat over a large stretch of the sea. You can improve their life of service by ensuring you follow a strict outboard motor maintenance regimen.

    The crucial detail is to keep the motor clean after every outing. You can use these tips to ensure your outboard engine lasts by using the following cleaning tips.

    Flush the engine after every outing

    The task of ensuring that your outboard motor is clean should be done after every trip. You have to develop the habit of flushing the engine, whether on a freshwater adventure or a saltwater outing.

    You can have an old motor design; you should buy a set of flushing “earmuffs” since the new models already have mounts. Connect a garden hose and turn on the water pump to flush the engine.

    Check the water pump to ensure it has a good flow

    While flushing the motor, carefully put your finger into the water stream, leaving the motor since it should be warm, not hot. If the stream output is weak, then there is debris in the outflow tube.

    If the flow is obstructed, switch off the engine and insert a small piece of wire into the tube and work it back and forth. Restart the engine again to confirm output. If the output is still the same, you need a new water impeller.

    Disconnect the fuel line if the boat needs to be stored

    When preparing your boat for long-term storage, disconnect the fuel line. Do this only after burning all oil in the carburetor to stop gumming up.

    If the flow is obstructed, switch off the engine and insert a small piece of wire into the tube and work it back and forth. Restart the engine again to confirm output. If the output is still the same, you need a new water impeller.

    Turn off key and clean mechanical components

    To ensure all moving parts remain fixed during cleaning, turn off the key or battery for electric outboard engines. You should then spray all moving parts with anti-corrosive

    Regular maintenance Tips

    Best Outboard Motor

    Replace the outboard engines and spark plugs whenever necessary. Since the spark plugs do not have a predetermined shelf life, you have to watch out for the plugs if the engine has high fuel quantities and doesn’t rev up regularly.

    You can use a spark tester to confirm the defects. It is safe to replace the spark plugs together with the wire associated with them.

    Make sure the fuel has no water. Water in an engine can lead to malfunction and damage components like spark plugs. Avoid using ethanol as a fuel additive to dissolve gaskets, seal, and hose leading to water intake.

    Use fresh oil at all times as outboard motors are extremely sensitive to impurities or grime. You have to ensure you only use the recommended fuel type of your engine manufacturer. It is common for a two-stroke engine to use oil and gas mixtures, while a four-stroke uses regular gas.

    Make sure all other parts are properly by checking the tank vent aspirate properly and the fuel tanks for signs of corrosion or damage. Ensure the fuel line properly fits and does not have any leaks or damage.

    Frequently Asked Questions

    After going through the different outboards in the market, you could still have some lingering questions. We have compiled a list of the most asked questions on the internet about outboards.

    Question: How often should you flush your outboard motor?

    Answer: Regularly flushing the outboards with fresh water is key to maintaining any outboard, whether in freshwater or saltwater. Most experts and manufacturers recommend a freshwater flush after every use to clear the passage of debris, saltwater residue, and scales that accumulate and restrict vital cooling water flow to the engine.

    Question: Why are outboard motors so unreliable?

    Answer: Most boat engines become unreliable after use due to poor maintenance. Some engines are indeed less reliable than others, but the most underlying issue among the outboards is low-quality materials, ill-maintenance, and overuse.

    Question: Does my fuel filter need to be replaced often?

    Answer: It is recommended that you replace the fuel filter for your tiller after 100 hours of operation or every three months.

    Question: How long should an Outboard last?

    Answer: The lifetime of an outboard is typically 1500 hours of operation when following the general guidelines. However, the longevity of a model can be anything from five years to 10 years. The outboard’s warranty is a crucial predictor of how long it should last.

    Question: Which is better: 2-stroke or 4-stroke outboard motor?

    Answer: An outboard’s efficiency is beyond the type of engine, but on a side-to-side comparison, each engine has the relative merits that make it a suitable choice for an outboard. Four-stroke engines have higher fuel economy, are quiet, have more torque and speed, while two-stroke engines tend to be light and accelerate faster.


    An overboard can give you a great experience at sea by helping you cruise, fish, and haul goods over a water body with relative ease. Only the most versatile engine can work on multiple boat sizes and depths. If you have a large boat, it is an excellent choice to get a four-stroke overboard.

    The best outboard that can be handy for anyone considering the costs and compatibility with a boat is the Honda  BF250. The engine offers high flexibility and control to the user and many technologies that make it practical for everyday use and sturdy in the most challenging conditions.
