I took the engine mounted fuel filter off of my 1989 130 hp yamaha and there was some water in the bottom of the bowl. I also have a spin on type fuel water seperator that i am going replace. I am an auto mechanic and we put alcohol in tanks that have a little water in them, about a quart to 20 gallons. do you know if this will be ok in an oil injected outboard? I sure hate to drain a 100 gallon tank that is full.
