I had a 150 Force before going to a 150 E-tec. A 120 should push your boat but not at any great speed. Mine ran great until coming into the harbour and shifting it into reverse. It would stall and I could not get it started again. Not a great time for your motor to stall. You can get most parts for them but I would not go to any great cost trying to rebuild it. I sold my 1999 150 Force last year for $800. If you can afford more, I would say stay away from the Force. Billy Mac
