I am looking at turning a 19' Bayliner bowrider into a fishing machine. My friend doing the work has offered me the following engine choices to go with it.<br /> 1995 Yamaha 90HP<br /> 1990 Yamaha 115HP<br /> 1989 Force 125HP<br /><br />I also use the boat parttime for skiing and tubing so I need takeoff power as well. The 90HP is like brand new but the boat is rated for 140hp and I think this would be underpowered. I am not sure about the 115HP as it is going to be rebuilt and the Force is in excellent shape, but I heard that it's HP rating is done at the powerhead whereas the Yamahas are taken at the prop. Plus I see lots of repair questions on the Force. I could also pick up a 100HP Mercury with one of those outboard plates but the cost is prohibitive $3400. cdn.<br />Any suggestions?
