I inherited a '71 65 HP Merc, 4 cyliner. Great engine. It runs like a dream. The only problem I have with it, is that it is a heavy son-of-a-gun and my back isn't what it used to be. I know ---"buy a new one" Unfortunately, that isn't in the cards. I've seen new aftermarket tilt and trim units, but I don't care to spend $500 on this old motor. I've browsed around on e-bay and there's no shortage of tilt and trims from fellas parting out their old motors. I'm wondering how difficult it would be to make something like that work with my old beast. I'm reasonably handy. I'm comfortable taking the motor off the transom and removing all the control cables. And where would a guy get info on which Mercury tilt and trims would be compatible with this motor? For instance, the last time I checked e-bay, there was a T&T from an '87 85 hp.
