Boat Fueling 101
Knowing the right type of fuel for your boat is a big step of boat fuel 101! Always be very careful to add the appropriate fuel to your boat.


DO read your boat’s owner manual.

Every boat has different fueling requirements, and it’s crucial to understand yours. Your boat’s manual will explain how much fuel it can hold, where the fuel tank is located, and any other essential fueling instructions.

DO use the correct fuel.

How you fuel your boat will vary a bit depending on what type of boat it is, and what sort of power system it has. Using the wrong fuel can cause significant damage to your boat’s engine. Always use the type of fuel that your boat’s manual recommends. Some boats require specific types of fuel, such as ethanol-free. Failing to use the right fuel will void your boat’s warranty and may lead to costly repairs.

DO fill up before departing.

It’s important to fill up your boat’s fuel tank before departing on a trip, rather than waiting until you’re already out on the water. This ensures that you won’t run out of fuel and get stranded. It’s also important to fill up your boat’s tank completely, as leaving air space at the top of the tank can lead to the buildup of condensation, which can damage the engine.

DO use a proper fuel nozzle.

Some boats have unique fuel fill systems that require a specific nozzle. Using a nozzle that’s the wrong size or shape can cause fuel to spill and damage your boat or cause a fire. Always use the fuel nozzle that’s designed to work with your boat.

DO keep fire extinguishers nearby.

Accidents can happen, even with the best of intentions. That’s why it’s essential to have a fire extinguisher on hand while fueling your boat. Make sure you know how to use it before you need it.

DON’T overfill the tank.

Overfilling the tank can cause fuel to spill, leading to damage to your boat or someone’s injury. Always fill the tank slowly and stop when the fuel reaches the fill line or automatic shut-off.

DON’T smoke or use any other open flame.

Smoking is a major fire risk when fueling your boat. Never smoke or use any other open flame on your boat, especially when fueling.

DON’T fill up in a hurry.

Fueling your boat isn’t a race. Always take the time to fill your boat’s tank slowly and carefully. Rushing the process can lead to accidents and damage your boat. Once you’re done, close the tank tightly and check for any drips. If there’s any fuel on the side of your boat, wipe it up with an absorbent pad and dispose of the pad properly.


Fueling your boat may seem like a simple task, but it’s one that requires careful attention to detail and a commitment to safety. Whether you’re a seasoned boater or just starting out, fueling your boat is ome  s of the most important and recurring aspects of owning and operating a vessel. Which is why following this fueling rule of thumb is so important. Each precaution has a good reason behind it, and is centered around keeping you, your passengers, and your boat safe.
