Do the sniff test, if it smells like kerosine get rid of it as you can. if it smells like gas use it a lawn mower or carbed cars as stated. Sealed gas for 2 years should not be written off. If you plan on leaving gas in a boat for extended periods of time invest in Sta-bil. it will hold gas quality for longer than that. I would be more concerned about the fuel in the carb AND fuel lines,fuel pump and filter! MLAOI'm in northern Los Angeles County (Santa Clarita), looking for a place to get rid of the 2+ year old gas in my boat.
