Ran the boat for the first time last week. Ran great for the first 1/2 hour, then would not run above 3000 rpm. Choke the motor and it would run.. so i think fuel pumps. Swap them out same thing today except 4000 rpms and choke does nothing. What next? fuel filter, maybe tank vent?

If will run with choke on then it's dirty carbs, need to remove and clean carbs.

after i replaced the fuel pumps the choke actually killed the motor.
