I'm a marine technology expert with a passion for all things related to the sea. I've spent years studying and working with various types of boats and their propulsion systems, which has given me a deep understanding of the different types of fuel used in boats and how they work.
Boats, much like other vehicles, require fuel to operate their engines. The type of fuel used in boats can vary greatly depending on the engine type, the size of the boat, and the intended use of the vessel. Here's a detailed look at the common types of fuel used in boats:
Gasoline Engines
Gasoline engines are commonly found in smaller boats and personal watercraft. They are lightweight and relatively inexpensive compared to diesel engines. Gasoline, or petrol as it's known outside of North America, is a hydrocarbon fuel that is derived from crude oil. It's a volatile fuel, which means it evaporates easily and can ignite quickly. This makes it suitable for high-revving engines that require quick combustion.
Diesel Engines
Diesel engines are more common in larger boats and commercial vessels due to their durability, fuel efficiency, and low-end torque. Diesel fuel is also derived from crude oil but has a higher energy content than gasoline. It's less volatile, which makes it safer to handle and store on a boat. Diesel engines operate on a different principle than gasoline engines, using compression ignition rather than spark ignition.
Alternative Fuels
As the world moves towards more sustainable and environmentally friendly practices, alternative fuels are becoming more prevalent in the marine industry. These include:
- Ethanol: An alcohol-based fuel that can be blended with gasoline. It's renewable and burns cleaner than traditional gasoline.
- Biodiesel: Made from vegetable oils or animal fats, biodiesel is a renewable fuel that can be used in diesel engines with little to no modification.
- LNG (Liquefied Natural Gas): LNG is becoming popular for larger vessels due to its lower emissions compared to diesel.
- Electric Propulsion: Electric boats are powered by batteries, which can be charged from the grid or through regenerative braking systems. They are emission-free at the point of use and are becoming more common in smaller boats and ferries.
Fuel Consumption and Efficiency
Both gasoline and diesel engines use about **0.6 pound of fuel per horsepower per hour**. This is a general figure and can vary based on engine efficiency and operating conditions. Diesel fuel, on average, contains about 140,000 BTUs per gallon, which is approximately 10 percent more energy than the same volume of gasoline. This higher energy content contributes to diesel engines' better fuel efficiency.
Where Does the Fuel Go?
When fuel is consumed in an engine, it undergoes a combustion process. The chemical energy stored in the fuel is converted into mechanical energy that powers the boat. Here's a brief overview of what happens:
1. Combustion: The fuel is mixed with air and ignited, creating a small explosion that pushes a piston or a turbine.
2. Power Transfer: The mechanical energy from the pistons or turbine is transferred to the crankshaft, which turns the propeller and moves the boat.
3. Exhaust: The combustion process produces exhaust gases, which are released into the atmosphere. Modern engines are designed to minimize harmful emissions.
4. Heat: Some of the energy is lost as heat during the combustion process and through the engine's cooling system.
In summary, the choice of fuel for a boat depends on various factors including engine type, boat size, and environmental considerations. While gasoline and diesel remain the most common fuels, alternative fuels and electric propulsion are gaining ground as the marine industry evolves towards more sustainable solutions.

Your engine uses the fuel you purchase in several ways.
