CJ7Rob, call Ken at PropGods. Some guys have the exact same boat/engine setup but do different things and need more or less of something in trade for that sweet spot. Ken guides you through questions and suggests. Good return policy.
Also, Fishtales, I do definitely get more lift. With the 3 blades I trimmed the motors out a decent amount, now it's just a small amount they seem to almost suck the boat up out of the wate. I'm sure this improves hole shot too, but I don't really notice hole shot, maybe a second or two, but not what I care about too much except in a fully loaded boat situation. And I do get the same WOT RPM as before, because if not you may be overloading the engines with too large of pitch or diameter. My speed is actually the same at WOT, although my GPMi has gone down 0.1
The other things I notice is my speed/rpm on plane can be lower due to the lift, AND my sweet spot for fuel/rpm/speed is about 2kts lower. But these are both desireable for me in the PNW with the gray days and gray logs and square waves. I'd prefer the sweet spot to be 25-28kts, not 30+.
But hey. It's all a compromise.
