I can't speak for the Crossfire but I have been warned by two marina's not to use gas with any ethanol in it in an outboard. They say the ethanol draws moisture and can ruin your engine. They recommend that if you have it in your tank that you completely use it all up in two weeks or less. They posted some pictures that show some nasty deposits they claim were caused by the ethanol. They showed pictures of a caramel like deposit at the bottom of a gas tank. Of course they sell ethanol free gas. I'm a little skeptical of their motives. What do you guy's think?

I would assume if the above is true it wouldn't be doing our cars much good either.

We have always used gas from the station in our previous boat a 5 liter V8, and would haul gas down the dock to save money. The marina charges about 40 to 50 cents more but it's ethanol free. If you use station gas they recommend that you use Stabil gas stabilizer. The cost of driving to the station and the cost of the Stabil costs more than just filling up at the marina.
