    OMC exhaust flapper alternative.

    They were omc yes. Tried two different types. Nothing fits. I want to do center risers but not sure how to make the conversion. Like what elbows I need and all that.

    OMC exhaust flapper alternative.

    What if I stick one of these on the back of the boat where the exhaust bellow goes. Renken you said home made. I've never seen these below the water line. Guess I'd just have to try it out and see how it behaves when I'm stopped.

    Alpha One Gen 2 impeller delete question

    My closed system is aftermarket. So you think the crank style impeller could pull enough water up through the drive to keep everything cool?

    1993 omc cobra 4.3L

    This is a mechanical fuel pump. It only pumps when the engine is turning. Take the fuel line off the carb and put a little bucket under it. Crank it a bit. If no fuel comes out then take off the pump. These older pumps are easy to rebuild. Take it apart and check the little black diaphragms...
