Stroked my 420's to 496, TRS drives. Runs 65 with the 21P props @ 5600. I'm going to try the 23P Mirage Plus and hope for 67-68. I might also try the 22P Bravo One for better cruising speed and give up a little top end. Sounds like our boats are running about the same power. Good luck, let us know your numbers.

Don't waste a lot of summer worrying about experimenting. Call BBLADES. He has a bad habbit of getting it right the first time. :coolcowboy:
