How to Improve Your Engine’s Fuel Efficiency

to save money on every trip

Fuel is one of the biggest operating expenses for any boat owner. Whether you’re out on the water for leisure, fishing, or work, improving the efficiency of your outboard engine not only helps you save money it also extends the life of your motor and reduces your environmental impact.

 

Keep Your Engine in Top Condition

Adjust the Trim for Better Navigation

A well-maintained engine consumes less fuel and performs better. Regular maintenance is key.

✔ Change the oil and filters regularly.
✔ Check the spark plugs and ignition system.
✔ Clean or replace the air filter.
✔ Inspect the fuel injection or carburetor system.

Engine trim the angle of the motor relative to the hull has a direct impact on fuel consumption. An improperly trimmed engine creates drag and forces the motor to work harder, burning more fuel.

✔ Adjust the trim according to speed and water conditions.
✔ Avoid excessive bow rise or dipping.
✔ Use automatic trim if your engine is equipped with it.

Control the weight and

the load distribution

Excess weight or uneven load distribution increases engine strain. Reducing unnecessary weight can make a big difference in fuel consumption.

✔ Remove equipment, tools, or accessories you don’t use.
✔ Distribute weight evenly on board to avoid the boat listing or sitting lower on one side.
✔ Consider the number of passengers and their placement.

Cruise at optimal speed

Many boaters accelerate more than necessary, not realizing that the most efficient point is at cruising speed.

✔ Every engine has a “sweet spot” (ideal RPM range) for peak performance.
✔ Check your engine’s manual or consult a technician to find that range.
✔ Maintain a steady speed whenever possible.

Use the right propeller

and quality fuel

The propeller is a key part of the propulsion system. A poorly sized propeller can increase fuel consumption by 10% or more.

✔ Make sure you have the right pitch for your boat and typical load.
✔ Avoid using damaged or deformed propellers.
✔ Consult with experts to evaluate whether your current prop is the best fit.

It may seem obvious, but using clean, high-quality fuel improves engine performance.

✔ Avoid mixing fuels or using old gasoline.
✔ Store fuel in clean tanks, away from direct sunlight.
✔ Use marine-grade fuel additives if necessary.

Don’t let excessive fuel consumption limit your adventures on the water.
