I don't think you'll gain much in the way of RPM's from raising with the Turbo prop. I have the same prop 25P, with a hydraulic jack 12" setback, runs the same as you describe, but RPMS are low as well. Doesn't matter where the motor is up and down for the most part, and I can run up to 1 inch below the pad. I have a worked 26P Trophy Plus, which I can pull more RPMS out of.

On second thought you might gain a little, since you are 10" behind the boat, the last 2 inches seems to make a big difference on this hull as far as getting into cleaner water.

Hope this helps.
