I have a 5hp Mercury outboard on my 192 that is having trouble running; I think related to fuel that has been in the tank since the winter. I did put stabilizer in the fuel but I suspect it's bad anyway. Question is; how do I go about getting rid of the fuel in the 1 gal internal tank and the 2 gal fuel can in the cockpit locker?This may be a stupid question, but how and where can I dispose of gasoline in a safe an clean way?
