my current prop is a SS vengeance 19P 14D. At WOT and 5000 RPM's gps speed is 49MPH at optimum trim. I have a deck boat (fairly heavy). Engine is a 5.0L MPI mercruiser with 1.47 gear ratio. Mfr recommended rpms (4600-5000 rpm) When its time to replace the prop I'd like to hit that 50MPH mark, What brand and size prop should I buy?
