    the impeller pump was not turning
    The hardest part of replacing the impeller for most folks is getting to the pump. Now since your pump was not turning, you either need to take yours apart and rebuild or buy new. If I had your engine serial it could be verified, but figuring you have Merc part number 46-8M0118068
