    Wrench for top of outdrive

    Does anyone know where I can get a wrench to fit the star-shaped bolts that hold the small square cover in place on the top of my (Mercruiser Alpha I) outdrive? Looks like a 3/8" 12-point socket might fit but in that size all I can readily find is 6-point sockets and I'm not even sure the...

    plastic tube at impeller pump outlet

    Above the pump in my (Alpha I) stern drive there's a short (4") plastic tube which fits into the outlet on the stern drive water pump and (when the lower unit is fitted to the upper unit) fits over a smaller diameter copper or brass tube in the upper unit. There seems to be no seal between the...
