I have 15*24 Hill signature eagle 4 on 300pm sportmaster, 23ft deep V.
Rpm max 5800 75mph, propshaft above 1.5 inch ( more higher - loose water pressure) , 10.5 inch setback, quite high trim, on low loaded boat.

What pitches of promax and bravo 1 xs should I try to gain rpm and speed with low and medium load weight?
