Boat mechanics at the Lake of the Ozarks say ethanol will melt gaskets and hoses on boats more than five years old.
That statement is BULL! With one exception. Some mid 1990s Mercs have a TSB out that advises changing the check valves in the fuel pump because the new gas causes the ends of the rubber valve to curl up. No melting of rubber! And no melting of gaskets! Next time you are out look around. There are a lot of old motors still purring along and ethanol has been out a long time now in Va., well over 5 years. But don't take just my word for that. Go to iBoats.com and ask there. Over 100,000 members.
