How muck to pitch??
Comming back from my 1st ride of the season.
Air temp 80', water 44'. no speed recorded as I don't have a gps.
Over the winter I have done the following mods to my gtx 215...
x charger, 42# injectors, 15/20r prop, bypassed resonnator.
At holeshot, I'm all over the limiter and only at 3/4 throttle, but at 30 mph and going WOT it jumps at 7700 and climbs up.
So I need to pitch my prop but what do I start with... 1 or 2 mm??

Sounds like you are cavitating on holeshot.
What are your rpm's at WOT at top speed ????

Didn't had a chance to try it at top speed but looks like I lost some (going with speedo) compared to last year (stock). 60 mph at 7700-7800rpm

Well... Took the pump appart to start pitching and maybee found some of my problem, found out the hose for the opas to be unpluged... was wondering why my ski felt more agressive on sharp turns, think I know why since the paddle stayed down acting like a rudder. Probably that caused me to loose a bit of top speed as well. Will se with new pitch maybee this afternoon.
