From time to time I use ethanol in both 2 cycle engines on our 15' Smokercraft when ethanol free gas isn't available, with no ill effects. But I take some additional precautions, which were recommended by the outboard shop that serviced both engines.

I had the carbs on both outboards rebuilt with ethanol tolerant seals (After the 15 HP kickers carb plugged up that is!!)

* Disconnect the fuel lines on both engines and run the outboard until the residual fuel is burned out after each use.

* I never leave the fuel in the tanks for more than a month.

* Removable tanks should be stored out of direct sunlight so the fuel isn't constantly heated and then cooled.

* If you're not going to use the engine for a while, dump the remaining fuel into a car or lawn mower and use it up.
