Were are looking at buying a 1991 Bayliner capri 20 foot cuddy cabin. The boat is in good shape but what concerns me is the 120 HP Force outboard. The seller states the motor was rebuilt (pistons, rings, etc) last year and runs good now. He did not say why it was rebuilt but there was three extra prop for it in a storage compartment (would this have anything to do with it). We are going to test drive it in a few days and any information would be appreciated since I have heard varying stories on this kind of motor. Thanks
