    Yes Bill, I believe you are correct….Marineengine.com was no help, they referred me to a breakdown for a standard 9.9…. I wish I had an OMC listing for water pump kits but don’t…Will call marineengine….D
    This engine is a conglomeration of old and new….New style 9.9-15 powerhead bolted to an old style 10hp style midsection/gearcase with some sort of an adapter to mate the new style powerhead to the old style midsection. The question is what diameter driveshaft was used….Will continue to investigate….D
