Hi,
I have a 2002 24' Tracker "Party Barge 240" pontoon boat with a 2002 Mercury (Tracker) 90 HP outboard. Current prop is 15" pitch, approx. 13-1/4" or 13-1/2" diameter, aluminum. At W.O.T with just me on the boat, the tach reads 5500 RPM. With the family (4-6 people) and "stuff" on board, the tach reads 5100 RPM at W.O.T. The recommended range for the motor is 5000-5500 RPM.
I would like to replace the aluminum prop with a stainless. Will the change in material affect the RPM any? In other words, should I buy the same pitch (15) and diameter in stainless or would I need to get something different?
Also, any recommendations on stainless props (brands, models, etc)?
Thanks for any help you can give!
