I have a 2001 - 2575 RL-2 25’toons powered with a mercury 90 horsepower 4 stroke. Came to me used w a Black Max 14 inch 13, pitch. 3 blade prop and has run great for the last four years. Had some prop damage & need a new Prop. The online Mercury prop finder, based upon the engine, size of the pontoon, load et cetera I should be using an 11 pitch. Most pontoon forums/online resources suggest higher pitches 13/15/19 etcetera? The engine plate indicates maximum RPM of 6000 with wide open throttle between 5,000-5,500. In most cases I never reach the 5000 to 5500 RPM's with the 13 pitch prop. With 2 of us on the boat wide open, my depth finder speedometer, we probably do 20 to 22 knots. Wondering if I should replace with another 13 pitch prop, drop down to 11 pitch as the mercury prop Finder suggests, or even go to a higher pitch?. #CONFUSED.
