7 Fuel Efficiency Tips for Boaters

Boating is about freedom—the thrill of open water, the sound of the engine humming, and the joy of a perfect day spent under the sun. But every boater knows one thing: fuel is one of the biggest expenses of ownership. Rising fuel costs and inefficiencies can quickly turn an enjoyable outing into a costly trip.

The good news? With a few smart habits and upgrades, you can significantly reduce fuel consumption while improving performance. At WOT Marine, known as the best boat shop in San Diego, we’ve helped countless boaters save money and maximize every drop of fuel. Here are our top seven tips for improving fuel efficiency.

1. Keep Your Hull Clean

A dirty hull creates drag, which forces your engine to work harder and burn more fuel. Even a thin layer of algae or barnacles can increase resistance dramatically.

Tip: Schedule regular cleanings and inspections, especially if your boat sits in the water for extended periods. A smooth hull means less drag and better efficiency.

If buildup has already caused performance issues, trust WOT Marine for expert boat repairs in San Diego—we’ll make sure your vessel runs like new.

2. Optimize Your Propeller

Your propeller has a direct impact on how efficiently your engine converts fuel into forward motion. The wrong size, pitch, or condition can waste energy, lower speed, and guzzle fuel.

Tip: Inspect your prop regularly for damage and consider upgrading to a prop matched specifically to your vessel and boating style.

Our team specializes in precision tuning and propeller upgrades, helping customers get the most from their engines. Pairing the right prop with one of the best boat repowers in San Diego is a game-changer for fuel efficiency.

3. Lighten the Load

Excess weight equals extra drag. Many boaters unknowingly carry unnecessary items—extra gear, outdated supplies, or waterlogged materials—that bog down performance.

Tip: Do a seasonal “spring cleaning” of your boat. Keep only what you need onboard and store or discard excess gear. You’ll be surprised how much fuel efficiency improves when your vessel isn’t weighed down.

4. Maintain Your Engine Regularly

Nothing hurts fuel economy like a poorly maintained engine. Dirty fuel filters, worn spark plugs, or clogged injectors all make your motor less efficient.

Tip: Stick to a strict maintenance schedule. Oil changes, filter replacements, and regular diagnostics are essential to keeping your engine running at peak efficiency.

At WOT Marine, we take pride in being the go-to team for boat repairs in San Diego, offering preventative care and precision service that saves you money at the pump.

5. Watch Your Speed and Trim

Boats, like cars, have an optimal cruising speed for fuel economy. Pushing beyond that “sweet spot” burns significantly more fuel. Likewise, improper trim settings can create drag that wastes energy.

Tip: Learn your boat’s most efficient RPM range and stick to it whenever possible. Adjust trim tabs to balance your boat and reduce resistance. Small changes in speed and trim can add up to big savings over time.

6. Invest in a Repower

If your engine is outdated or inefficient, no amount of cleaning or adjusting will fully solve the problem. Repowering your boat with a new, modern engine is one of the smartest long-term ways to improve fuel efficiency.

Today’s outboards are lighter, cleaner, and significantly more efficient than older models. Repowering can reduce fuel consumption by up to 30%—and deliver more horsepower while doing it.

At WOT Marine, we’re known for providing the best boat repowers in San Diego, helping boaters upgrade to engines that save fuel, cut emissions, and improve overall performance.

7. Plan Smarter Trips

Fuel efficiency isn’t only about your boat—it’s also about how you use it. Constantly idling, unnecessary detours, or running at full throttle for extended periods all eat into fuel economy.

Tip: Use modern GPS and chartplotters to plan the most direct, efficient routes. Combine shorter trips into one outing when possible, and avoid extended idling. Smarter planning means less fuel wasted and more time enjoying the water.

Improving fuel efficiency isn’t just about saving money—it also extends the life of your engine and reduces environmental impact. Efficient boats require fewer boat repairs in San Diego, perform more reliably, and leave you with extra cash to spend on the adventures you truly enjoy.
