    Yup that’s the same case I have. I think you’re right about the grommet. There wasn’t one in there when I got the motor so it must have been lost and no one replaced it. I ordered one today and will hopefully have it Friday and test it out. New water pump parts are on the way with a new housing that has the anti cavitation plate on it which mine does not have.

    Do you think the grommet has to be flush with the lower unit or is there a gap between the water channel and grommet?
