this is on a 79 Sea Star with a 350 engine. Its an OMC Stern Drive model #982141 serial # W190665. Can anyone tell me what I need to look for to find parts. The man who owns it said he was told that it broke a shaft and its still torn apart but I couldnt see anything wrong. The only thing I saw was some wear at the rear where everything bolts to the boat, where the motor joins the outer unit.
