Wondering what best prop pitch would be to maximize speed when pulling a skier or tube. Have a 2003 90 horse 2 stroke on a 21' Misty Harbor pontoon. Gear ratio is 2.33. Current prop is 14 x 13 but damaged. WOT is about 5800 (should be around 5500 or a little less I think but may be due to damaged prop). Top speed is about 24-26 and around 23 with 150lb skier. Have looked at Black Max Extra Cup - wondering if extra cup really solves some cavitation issues. Partial to aluminum versus stainless and 3 blade versus 4 but could be swayed. Have done the calculator and it says 13 or 14 pitch but really would like some feedback on tradeoffs of power versus speed. Thanks for any input.
