I have a 24ft Thompson HT and did mount a 8 hp motor on it. I tied it to outdrive for steering. But the big problem with that boat is that they set so high out of the water that they are extreamly hard to raise and lower just from a reach factor. I just ended up taking it off and went back to trolling with big motor as I had always done. Taking it off made a major difference for me running on plane that I noticed right away. Not trying to scar you just what I ran into.
