Re: '84 Mercury 50HP lower unit installation.
Hello all,<br /> This is my second time here and since the information was very very helpful last time, I am posting my most recent boat battle. <br /> I acquired an '84 Mercury 50 last season with the lower unit already removed. I replaced the water pump and now am attempting to install the lower unit. I got it to go in yesterday all the way up to approximatley 1/16 of an inch out. It won't mate to the motor. Now, on the spline in the front of the lower unit there is a round looking washer type piece. Now, I was wondering which way that piece goes into the motor. It looks as if the part is like a gear stoppage piece or something. I do have a book I got from the library, but I think because of the year, it is very vague. The lower unit in the book is not exactly like mine. So I don't know what that piece is exactly. Please help. Thanks,<br /> GreatSouthBay
