Thanks for the update. My boat is still at the marina. Glad I still have my old boat, otherwise this summer would have been a total washout.

So far we've installed a sparate fuel tank no fix, changed out the power pack no fix. Changed the VRO pump no fix. Not sure what is next.

Symptoms are still same. Runs very strong when starting out and while under power. After shut off for 15 minutes after 15 seconds after restarting the engine breaks up and no power. Next morning runs fine.
It acts as if the chokle gets stuck on.
I'm also thinking it could be the cylinder cut out switch going bad?

When it gets fixed I'll post it.
