Just wondering what props / pitch etc people are using. Using mercury's prop program to try and get best fit. So far I've tried Bravo 22 pitch 4 blade - cavitates a bit when getting out of hole 3500 rpm at 40 mph, 5084rpm at max 57 mph. The new Enertia Eco 23 pitch - cavitates a lot overreving engines / almost unable to get onto plane but once up goes fine 3200rpm at 40mph, 4000rpm at 50mph, 4354rpm at 59mph - these props are obviously too high pitch. Rev 4 19 pitch (my old props), no cavitation and 4050rpm at 40mph, 5200rpm at 54mph - so assuming pitch is too low.
Engines/Drives are new Bravo 1 300hp x 2, max revs around 5200.
I'm thinking to try Enertia Eco 21 and Rev 4 21. But has anybody got any other suggestions? One thing I'm surprised about is the props cavitating if the pitch is too high? - is this usual? Drives are full way down at this point...
Thanks
