Boat wont start after it warms up

[burwell.aj]

I just bought my first boat a week ago and took it out this past weekend. It is an 86 skier, it runs great except for once it warms if i kill the engine it doesnt want to start back up if i sit and float for a half hour or so it will. I can jump it across the cylinoid and it will fire right back up, i also put a new cylinoid on it. Anyone have any ideas what could be wrong?

Thanks

sounds like an auxiliary fuel pump may be the answer.

im pretty sure i have mechanical fuel pump. the boat wont even turn over if i try to use the key.

My friend had an 86' ski nautique with the same problem. We never did figure it out, good luck. It could actually be a relay but you'll have to trace all the wires for the ignition, lot's of work but it can be done..
