21 inch pitch,dam that sounds like a big pitch to me,I have a 150 black max and my prop is 15 x17 and that's perfect ,maybe I'm missing something.
Steplift20, you are correct, could only get about 4500 rpm out of 21 pitch. Tried 15 x 17 this weekend. Lots better, 5300 or 5400 top end now and of course better holeshot. Running cooler too.
