  • HELP!! cant get my boat to plain out

    I have a 1986 venturer 150 mercury motor and my motor runs fine when its out of water with ear muffs.. But when i put it in water it starts fine but when i turn up the throttle it bogs down and i cant get the boat to plain out.. I have changed 1 of the spark plugs and cleaned the carbs with the spray, needing to know what i can do to get my boat to plain out and run right!! Thanks

    Sounds like a fuel delivery problem.Probably running lean.Running on muffs doesn't mean much except it does run.After being sure its running on all cylinders I would rebuild the carb(s).and fuel pump.

      I agree, its not getting fuel and/or not firing on all the cylinders.

        I would ask this question in the Mercury forum.Not really a prop issue,unless hub spun.
