Can some one with a Force book help me? I have a 120 Force outboard, that is on a 18.6 Bayliner 1989 model center console. I dont know what size and pitch that it need, but I bought it used. and the original prop that was on there has been changed one time ,I wanted to replace the prop that's on the motor right now, but Iboat cant tell me either. please do help with the suggested RPM also..thanks all

Re: prop size and pitch

5000 - 5500 rpm, lightly loaded.

get all the numbers off the prop and post them, on the prop forum.
