Re: Yanmar 3gm stops at random underway!

Had similar symptoms on a Volvo. Turned out my emergency fuel shutoff had been inadvertently nearly closed causing a fuel delivery problem. Engine would start and after a few seconds sputter and die. Wait a minute or two and she started well, then again died. Thought it was a plugged filter, but occurred even after changing filters. Took a while to diagnose, but opening the valve fully resolved the issue.

Re: Yanmar 3gm stops at random underway!

How did a gallon of water get into the fuel tank? I guess in dry So California that would never happen. How did you end up finding out? Do you have a fuel/water glass seperator?
