I recently bought a new fuel injected outboard motor for my new boat. The service manager advised me to put a fuel additive in the gas tank. He said the alcohol in the gas starts to separate out almost immediately. When it does, it attacks the fuel lines and seals in the engine. An additive keeps the alcohol from separating. For a few dollars, I can add less than 1/4 cup of additive to my three gal. fuel tank and prevent all of these problems. E
Try to find E10, or ethanol-free gasoline for your boat:
