If you’re like most boat owners, you’re always looking for ways to save money. One way to do that is to increase your boat’s fuel efficiency, especially with current gasoline prices. In this article, we’ll show you how to do just that.

The Basics of Boat Fuel Efficiency

Boat owners often overlook boat fuel efficiency but it is a crucial aspect to consider if you want to save money and extend the life of your boat. You can do a few basic things to increase your boat’s fuel efficiency.

First, make sure your boat is properly tuned. A well-tuned engine will use less fuel and produce less pollution. You should also check your boat’s propeller regularly to ensure it is in good condition. A damaged or bent propeller can cause your engine to work harder and use more fuel.

Second, be mindful of your speed when you’re out on the water. Faster speeds use more fuel, so try to maintain a steady speed rather than constantly accelerating and decelerating. If you’re looking to save even more fuel, consider investing in a trolling motor. Trolling motors are designed for slow, steady speeds and can help you save a significant amount of fuel over time.

Finally, keep an eye on your weight. extra weight will make your boat less efficient and use more fuel. So, if you’re carrying around extra gear that you don’t need, leave it at home.

By following these simple tips, you can improve your boat’s fuel efficiency and save money in the long run.

Top Tips to Improve Your Boat’s Fuel Efficiency

  1. Keep your boat well-maintained and clean. A well-tuned engine will run more efficiently and use less fuel.
  2. Plan your trips carefully. Make sure you know where you’re going and how long you’ll be out so you can avoid wasting fuel by idling or running in circles.
  3. Slow down! Cruising at lower speeds uses less fuel than running at full throttle.
  4. Use the wind to your advantage. If there’s a good breeze, let Mother Nature do some of the work and save some fuel in the process.
  5. Trim your boat properly. An unbalanced or improperly trimmed boat is less efficient and will use more fuel than one that’s been trimmed correctly.
  6. Reduce drag on your boat. Anything that causes drag, such as an open hatch or tow line, will increase fuel consumption.
  7. Don’t overload your boat. A heavier boat uses more fuel than a lighter one, so keep it as light as possible without sacrificing safety.
  8. Use the right kind of oil for your engine type. The wrong oil can cause increased friction and lead to higher fuel consumption.

Monitor Your Boat’s Fuel Usage

One way to increase your boat’s fuel efficiency is to monitor your boat’s fuel usage. You can do this by keeping track of how much fuel you use over time. This will help you to identify patterns in your fuel usage and make adjustments accordingly. Additionally, you can use a fuel consumption calculator to estimate your boat’s fuel usage. By monitoring your boat’s fuel usage, you can make changes to improve your boat’s fuel efficiency.

Use the Right Type of Fuel

If you want your boat to be fuel-efficient, you need to make sure you’re using the right type of fuel. There are two main types of fuel that boats use: gas and diesel. Gas is typically cheaper than diesel, but it’s also less efficient. Diesel, on the other hand, is more expensive but it’s also more efficient. So, if you’re looking to save money on fuel, you should use diesel.

Another way to make your boat more fuel-efficient is to use a lower octane fuel. Octane is a measure of a fuel’s ability to resist “knocking” or “pinging” during combustion, and it’s also a measure of a fuel’s ability to resist pre-ignition and “knocking” or “pinging” during combustion. The higher the octane rating, the more resistant the fuel is to knocking. However, higher octane fuels are also more expensive. So, if you’re looking to save money on fuel, you should use a lower octane fuel.

Finally, you can also improve your boat’s fuel efficiency by making sure that your boat is properly maintained. This includes things like regularly checking your boat’s engine oil level and changing

Store Your Boat’s Fuel Properly

One of the best ways to ensure your boat’s fuel efficiency is to store your fuel properly. Over time, fuel can degrade and become less effective, so it’s important to store it in a cool, dark place. You can also add stabilizers to your fuel to help it last longer. Additionally, make sure you’re using the correct grade of fuel for your boat. Using a lower grade than recommended can actually decrease your boat’s fuel efficiency.

Maintain Your Boat Regularly

If you want to increase your boat’s fuel efficiency, one of the best things you can do is to maintain it regularly. This means keeping the hull and engine clean, as well as making sure all the moving parts are well-lubricated. You should also check your boat’s bottom for any growth that could be affecting its performance. By taking good care of your boat, you’ll not only improve its fuel efficiency but also its overall performance and longevity.


Increasing your boat’s fuel efficiency is a great way to save money and help the environment. You can do a few simple things to make your boat more fuel-efficient, such as keeping the hull clean and free of debris, using the right oil for your engine, and avoiding excessive speeds. By following these tips, you’ll be able to enjoy your time on the water while also doing your part to protect our planet.
