In the boat by myself yesterday, I was @ 47-48mph at just under 5000 rpm at WOT. Crusinge speed at 3600 rpm was 30mph.
Wondering if I would be happier going to a 21 inch?

hi Paul
Sounds like you were somewhat lucky with that one.. As for a switch to a 21" prop; you will likely lose your hole shot & low end punch, your WOT rpms will drop by about 400 and you might gain 2-3 mph on your top end. If you do a lot of tubing / wakeboarding or skiing, its my opinion you wont like the change. If you are simply a cruiser then the change makes sense. Personally & if the finances can afford it, i like the idea of having 2 props using one for each type of boating.
I went from a 3 blade - 21" to a 4 blade - 20" SS and am getting similar numbers (48-49 mph at 4900 WOT rpms) with the bonus of gaining some considerable low & mid range punch on my boat. I keep the 21" around as a spare now.
