Boat runs great for 30 minutes then i feel it's running on 80% power. Funny thing is that when it's running poorly, I can push trim up or down and the motor gains RPMs. If I turn it off and let it sit for only a minute or 2,it runs well again for a short while. I'm confused as to whether it is a fuel or electrical issue. I run the blowers at all times. Started at the end of last year and has been bugging me since.
To date I have replaced plugs ,wires, rotor and distributor cap. Replaced coil, trim and starter relays as well as looked for any unplugged wires.
I have replaced fuel filter/ water seperator, fuel line from tank as well as the anti siphon valve. I even wrapped the metal fuel lines with a foam tubing to help keep fuel from vaporizing. I even blew out the vent line from tank ( overflow line )
Please help
