Hey everybody. Dont kill me on this post, be aware I have very little knowledge about outboard motors. So I recently bought a fishing boat that came with a nice Mariner 90hp. Runs great and has power trim. However I was able to pick up a nice running 1971 Johnson 125hp and controls for $100. It does not have power trim. I have searched for what power trim will work on this motor and have failed in my search. I was hoping my Mariner power trim would work but from the looks of it, they are not compatible. So can someone point me in the right direction of what I can use? I have looked at the cmc units, but if I could use a johnson unit Id like to. Also it appears that I might need a mounting plate for the transom for this motor? The Mariner and the Johnson hardware looks completely different. If I were to go with a cmc unit do those mount right to the boat and the motor right to the cmc or is there something else I need?
