I have a 63 merc 65hp 4cyl outboard. I was told by a union mechanic that I didnt need to winterize the motor, just to leave it down and start it to make sure all the water was out, unfortunetly he was the only one I talked to about it, anyways the gear oil was never drained. I started it and was getting it ready for summer when I noticed it wasnt shifting into gear, I looked at the prop, It was sticking out it seemed like, so I took it off and realized that thers a nut holding in an aluminum housing in there, the aluminum housing is broken and pushed past the nut (this was a real disappointment,I just put in a new floor,carepet,lights,etc...)I have a whole parts motor as well but the upper part of the lower unit is out in that, I was wondering if you need any special tools to take that apart or if you know exactly what to do with it, I dont want to mess it up any worse. <br /> Thanks,Dennis
