The main problem with ethanol in marine use is that alcohol attracts
water. So if your boat sits in the water at a marina I would avoid
anything with ethanol. If you are trailering then I would recomend
either leaving the tank as empty as possible or keeping it full. A
half full tank will collect the most water because the fuel will expand
and contract with temp changes and you have a lot of space for humid
air to be in the tank.

I've got a 1979 Silverton with Chrylser M360B engines and Carter 4bbls. The
gas tank is aluminum, so that shouldn't be a problem. The fuel hoses can be
replaced easily enough. However, has anyone had experience or know whether
engines this old will run OK on 10% ethanol fuel? Will I have to mod the
carbs?
