Hello all I love reading these forums here on BBC. Although this isn't regarding my motor on my bass boat I do have a question to ask. I purchased a 1992 D75 75hp from an individual and it doesn't seem to have as much power as I thought it would. I put it on a 20 ft pontoon. It will run approx 15mph...so I started thinking. Maybe it has the wrong prop on it. So what prop would you all suggest for this motor? Thanks for the help and suggestions...
