Boats use the same gas as cars do; the only difference between the boats and car’s gas is the price. A gas at a gas station is a bit cheaper compared to the gas at the marina due to supply and demand. But the big boats (ships) use some different fuels depending on the engine design and type.
What grade of gas is best for a boat?
All current outboard, sterndrive and inboard gasoline engines are designed to operate safely on fuel with no more than 10 percent ethanol (known as E10), and under no circumstance should fuel with more than 10 percent ethanol (such as E15 or E85) be used in a marine engine.
