Outboard Motor Buying Guide


While sticking within your budget, it’s always good to consider all the other aspects. For instance, thinking about the long-term impact is crucial to arriving at the ideal outboard motor that meets your preferences. Some of the factors you need to look at include:

The Size of Your Boat

Checking and confirming your boat size is not only a good consideration but it’s also vital. If you get the measurements wrong, it can result in a string of problems. For example, if your boat is bigger than what the outboard can handle, the motor will overwork itself and wear away fast.

This could end up creating potential safety issues with the boat’s plane. On the other hand, a large motor fitted on a small boat can burn the spark plugs and cause overheating.

Outboard Motor Type

When buying an outboard you can either choose a 2-stroke or a 4-stroke. This depends mostly on your boating lifestyle and expectations. For instance, you need a 2-stroke motor if you like taking your boat on occasional fishing trips. It’s light, affordable, and easy to repair.

Alternatively, opt for a 4-stroke motor if your expectation is power-packed performance. The main difference between the two is that 4-stroke motors function on gas alone while a 2-stroke works with a mixture of both gas and oil.

Type of Fuel Injection

There are 3 different fuel injection systems for outboard motors. They can either use a carbureted system, Electronic Fuel Injection (EFI), or Direct Fuel Injection (DFI). How they operate makes the difference.

  • A carburated system which is the oldest lags behind EFI and DFI alternatives in terms of fuel economy. The model relies on the airflow and fuel amount that enters the engine
  • DFI systems are precise. They inject fuel right into the engine cylinders
  • EFI models control the air and fuel using electronic systems

Among the 3 types, carbureted systems are the cheapest. However, both DFI and EFI come out as far better choices when you weigh in all the qualities.

Fuel Efficiency

A 3-cylinder is going to use less fuel than a 4-cylinder engine. The less weight a motor has to move contributes to fuel efficiency. However, a professional boater might look at it from a different perspective.

When you put a small motor in a big boat, the fuel savings you get with the 3-cylinder will now have to work extra hard. As a result, it will require more fuel to operate. This is when purchasing a 4-cylinder becomes the smarter decision.

The Horsepower

Get the right horsepower for your boat if you want optimal performance from your outboard motor. You need to ask yourself a few questions before determining how much horsepower you need. They include:

  • How fast do you want to ride?
  • How much are you concerned about fuel?
  • How many passengers do you intend to carry?

Next, you need to factor in the size of your boat, after answering the questions.

Small Boats

These include dinghies, sailboats, and canoes. A maximum of 10 horsepower is enough for lake boating and smaller bodies of water.

Long and Light Boats

Long boats are usually around 10 to 15 feet. For example, the 10-foot and 15-foot aluminum or fiberglass boats don’t need a ton of horsepower to get going. For a decent amount of power, you’ll only need 15 to 20 horsepower.

Boats Ranging 15 To 25 Feet

Most recreational boats including coastal vessels used for activities such as fishing or cruising in the ocean fall into this category. Take note 75 – 90 horsepower provides enough power to do recreational activities along the shore. However, if you prefer traveling far and faster, then you need more horsepower. AT this point, think in the range of 300 horsepower or more.

Boats Over 25 Feet

Boats of this size perform well with 2 outboard motors ranging from 200 – 300 horsepower. A single outboard is not ideal. The extra power enables you to make a quick comeback after going for some distance. If you are into fishing, this is something you don’t want to miss.

Hull Capacity

Before deciding on your ideal choice, ensure that your boat’s hull can handle the weight. If you have an older boat, you can attest to this. It’s the case if the boat was designed for the old school 2-stroke motors. Today’s outboard motors are heavier and bigger.

When choosing a 4-stroke motor, you should aim at staying within 20 to 40 pounds of your original motor’s weight. Something you need to remember is that a lighter motor creates less draft.


Outboard Motor

After buying an outboard, you need to take care of it if you want to get the most value for your money. Regular maintenance prolongs your motor’s lifespan. Here are some maintenance tips for your motor.

  • Always check for any signs of water in the fuel
  • Check the fuel tank to ensure no corrosion or damage
  • Ensure that you periodically inspect the primer bulb and fuel line for any signs of wear and tear. This helps prevent leaks and the formation of weak spots

What To Do After Every Boat Ride

If you want your outboard to serve you for years, ensure you follow the following instructions.

  • You need to flush out your engine after a ride with your watercraft. It doesn’t matter whether you’ve spent the whole day in a freshwater lake or not
  • As you flush, check the water flow in the water pump. Disconnect the fuel line and burn out all the fuel in the carburetor once the flushing is complete
  • Observe the engine cowling to confirm whether there are any signs of leakage. Ensure you consult a certified marine technician or mechanic if you find one
  • Next, wipe down all the parts and spray an anti-corrosive coating. A lubricant should then be applied to all the moving parts
  • Finally, cover your engine with a canvas or plastic material
