And I've been on two boats with yamahas that broke down offshore. So what? Maintenance is required on every outboard, especially one that is 14 years old.

I was on 3 Yamaha powered boats last week and they all have major engine problems. Triple F350s with power heads corroding internally and a blown lower unit, an F300 with a thrust bearing on its way out requiring power head replacement and an F150 whose owner neglected valve train service and will require power head replacement. What should that tell me about Yamaha?

Well, just heard back from the mechanic on what the problem is. Apparently the liner on the inside of the fuel hose came undone in little pieces and was scattered throughout the fuel system. After doing a little research, this looks to be a pretty common problem on Mercury motors.

Sounds like you got the issue resolved. Ethanol destroying the inner lining of fuel line if not a brand specific issue. Mercury is not the only brand who suffers from the devestating effects of ethanol. Just this year alone we have replaced fuel lines and cleaned fuel systems on Mercury, Suzuki, Yamaha, Tohatsu, Johnson/Evinrude, Honda, and even some sterndrives. Several had "ethanol resistant" fuel line, but still failed and required replacement.
