Recently puchased a "new to me" tri-hull. It has a 1971 merc 165 outdrive ser. # 3080452. I was planning to start and run it here soon just to make sure everything is in check before i go spendin money to redo the boat. Was going to change gear oil today and after alittle looking i realized it has no drain for the od. It has the top vent plug but absolutely no drain anywhere. I belive it to be a pre-alpha has the rounded cav. plate and the lifting hole on top. Does anybody have any ideas. Im used to always seeing to plugs on em
