I totally agree with Bob. My Yamaha manual says the same as his Merc. Also, my Honda 4 stoke can also tolerate 10% ethanol. I'd be careful of adding the "dry gas" that was mentioned earlier in the posts. Methanol is a very corrosive alcohol and is hard on the rubber gaskets, etc in your fuel system. Not bad, if you're going through a lot of gas quickly, but for long term things isoproanol (iso propyl alcohol) is much better. Seafoam is dam expensive to run with every tank of gas (my boat needs about two bottles @$9 a pop, per tank of gas), but it works to cure some short-term problems like uneven idiling, etc. During the winters and for long term storage I do use Stabil in my tanks of ALL my engines (chain saw, wood splitter, weedeater, lawn mowers, snowmobile, boat engines, etc.).
