I took the boat out last sun, and it was running ok with a 3 RPM loss at WOT. As the day went I lost all power and had to idle back to the ramp. I was able to do alittle trouble shooting today and found something that might be helpful. I removed the choke body and fond that the needle valve set was backed off about three turns. After re-securing seat boat runs as well as expected. Strange fix hope it helps someone.

Ya I replaced the fuel filter fuel line and installed a new choke body or upper carb. gasket. Don't want any more fuel problems this year.
