Even more than the gas in your car, the gas in your boat needs special care to keep your engine running at peak performance. Gasoline begins to go bad within about two weeks. When left untreated, some of the fuel components begin to oxidize and form a gum-like substance. The substance settles in fuel lines and tanks, carburetors and injectors. When you try to burn this fuel, deposits can form in the combustion chamber. Over time, these deposits build up and reduce your engine’s performance.
