"Gasohol"
Alcohol will separate from the gasoline during winter storage. This separation lowers the effective octane rating of the fuel. While most cars dont have fiberglass fuel tanks, some boats do. The alcohol reacts with the glass and causes contamination and damages the tanks. Bad stuff will be going to the carb, check those fuel filters closely! Could this also be a problem with 'fuel cells'?

Alcohol sucks up water like a sponge! Leaving the tank half full is inviting trouble, fill it up. Of course that leaves you with a full tank of 'ultra low octane' come summer time. Perhaps the timing should be backed off for that first tank of 'spring driving weather'?

The boating community is just starting to wake up and smell the coffee on this issue, which will become more pronounced as alcohol is here to stay.
