Correct prop pitch

[wrench]

you might want to check your engine height first as if it's too low you will lose RPMs there.

We came in third in the blend off....it was a fun night.

Is the prop you have now aluminum? If so, just changing to a SS prop will add RPM. I agree with most of the other posts....a 15 x 15 SS prop (not cupped) should get you where you want to be.

going to stainless will drop rpm, it will have less slippage age more rotating mass therefor putting more load on the motor. adding cups will cause it to drop even more
