Thread: Impeller question?
07-25-2013, 10:22 PM #1
So I have a 14/19 in my ski now and even in the 90 deg water i am on the stock limiter, i have repitched 4mm and its still at 8150-8200 rpm. I have a 15/20r impeller i could put on it but i dont want to be over propped. What do you guys think. should i throw it on and de pitch it as needed?
4in front intake
mod water box
3in rear exhaust
modified ride plate.
14/19 at the moment.

Your not ready for the 15/20 then (maybe in the winter). Keep adding pitch to that 14/19 to get you off the limiter... your close with it!

Yes still on the stock nozzle. I'm gonna throw it on and see where the rpm is at

So I never got it answered. But how many mm can you pitch the prop before it becomes inefficient?
