I'm officially a fanatic! Great site, guys. I'm looking for an outdrive, upper and lower unit for my 1977 Fiberform, and as I'm looking at these units on Ebay, etc, they're for anywhere from 1970-80' and they're from 120-230, and the outdrives all look the same as far as gear sproket, mounting, casing. I'm wondering if somebody can tell me if I can put a 120 on a 175; or if any of these things are interchangeable. Also need to find one of these animals, if anybody has an idea about where to get one. THANKS!
