I have a yamaha wavejammer that started really nice on the trailer, but as soon as I put it in the water it quit and won't start. It has good spark\compression,and being that it ran good, never got used and died after being bounced around I tend to think fuel problem,but it appears to draw fuel through the filter when cranked.I have a long winter to fix it but it sure would help if someone could point me in the right direction.
