If you have any question about the operation or maintenance of your outboard motor, please consult a Yamaha dealer. [. . . ] As gasoline has changed, the amount of additives such as aromatics and oxygenates has increased. These additives are important for the engines in passenger cars, but they can have detrimental effects in marine engines, because of increased deposits in the combustion chamber. When enough deposits collect, piston rings begin sticking. Performance drops and engine wear increases dramatically. While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free Fuel Additive has repeatedly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring-land area, and fuel system components. Follow product labeling for use instructions. 1. Gasoline Replace the fuel tank cap and close tightly. Shake the fuel tank to mix the fuel thoroughly. Make sure that the oil and gasoline are mixed.
