Ok, here's the scoop. I have a 16 ft carlson cvx outboard that I would like to convert to Z drive since I have a boat and a hot little SBC laying around. What I don't have is a drive. I know where I can get a complete alpha leg, gimble mount plate, pump and cylinders. I'll be needing steering and gosh knows what else. Question is,,,,,,should everything thing I get be for the alpha of that model (pre, gen1, gen 2) like steering ram and bellhousing? I know the uppers and lowers have to be the same make.
