I've got it powered with a 1987 Yamaha Pro V-150. Runs Great. When I bought the boat, the Yami came with the boat, only problem, it had a 20" shaft. 25" transom! I bought a 5" lower unit extension from Bay Manufacturing in Ohio. It works great. I had the power head rebuilt and I ran it about 30 or 40 days last year without a hitch. Also came with a prop made for a 40' Donzi!! I didn't pick up on that one til I sea trialed it after some work. Didn't have a single working gauge in the console. Lots of holes though.
Man, have I got stories on this boat. Its also my first boat that I redid.
