I have a force 150 that runs my 18ft cobra 47mph at 5400rpms, which is the peak of my recommended rpm range. I am adding boyesen power reeds which will add 100-300 rpms. Should I upgrade to a 23p prop? I heard the 20p 4 blade is equivalent to a 22p 3 blade. I pull alot of skiers, wakeboarders, and tubers. Which prop will do what and which is the better choice for me?
