Looking for some help. I have an 83 Forester Pro Bass 162 with a 1985 Mariner 115hp (Tower of power inline 6cly). The RPM meter when it does work flirts around 3800 rpm at full throttle. Th boat is only 16.2 feet long and even with just myself in the boat, I can only get it up to 39mph on a calm day. The prop has a few nicks in it but is in decent shape no major chips taken out or anything. My question is this. I feel like i should be getting more speed out of this boat. It does have a hydrofoil on it white helps my hole shots. I tried taking it off and couldn't even get the boat to go over 33mph. When full throttle in most boats, you can trim up the motor and find the sweet spot where it rides smoother and a little faster. With this boat, trim al the way down at hole shot, once on plane the trim doesn't help in fact actually seems to almost hurt the boats speed when trimming up. Im currently looking at a jack plate to try and get less drag out on take off and hopefully after fine tuning, a better top end speed. Does anyone have a similar set up (boat wise) as i do and if so what your numbers looking like for speed and RPM? Any and all help is appreciated! -Sam
