10% ethanol fuel mixture....needs stabil???

[dolphinsfan1966]

I've been told recently that if you run a 10% blend gasoline/ethanol you need to add stabil to the fuel to ensure the engine doesn't go bad....such as the rubber parts in the carb reed valves etc etc etc.

I Just bought this ski and want to ensure it lasts a while, have any of you guys had a problem with the ethanol?
