There is a possibility of increased problems for ethanol. It is unavoidable
in many places though. Because it contains alcohol it attracts water. It
is suggested that you not leave it in the tanks for extended periods. You
should check the water separator more frequently.

So I just bought a new boat, and am very much a newbie. The biggest
shock is being told I must stay away from reformulated gas with
ethanol. Yikes. Is that possible to do in Washington State without
paying an extra $1/gallon using Marina gas? By using it, am I really
destroying the engine, or is it more-- "just check the fuel lines and
system more often" kinda thing? Are there land based gas station
brands that don't use ethanol? I read a previous thread that
mentioned that this is not a problem with engines after '87, but my
'04 manual clearly states to avoid using fuel mixed with Ethanol.
