I was told to put another thread up in this here as my boat (16' Evan-john v4 jet) is an over grown jet ski. Well ya okay i'll buy that. But I'm looking for a name to a part that was cracked on mine. My book tells VERY little about jets. Its a grey alum pump of some sort bolted to the engine, almost looks like a water pump but is huge. Sits below the engine, right on top of the transmission(drive shaft for the jet prop. any help would be great and if you know of a salvage place great too. I wish I could give pictures but my piece is gone.
