I have a boat built in 1978. Last year I trailered my boat down to VA for a several weeks while I was on contract work. Because of ethanol I encountered a major problem. According to the marine mechanic, I had a fibreglas tank with a rubber membrane. The ethanol softened the rubber and the rubber was melting. So he says. I had to put in a new metal gas tank. replace all the rubber gas lines, and replace all the gaskets in the carbureator to newer materials. About $4000 later, I am hearing I am still not out of danger? Ethanol breaks down after a month?
Rubberguy. Care to comment on why ethanol is breaking down old rubber?
Or did I get taken by an unscrupulus mechanic?
