Re: prop

If you go with a 23 pitch it should drop it down to about 5000. I believe a 4 blade will drop it down further, as my Pro Pulse composite did that after running a 3 blade for a while.

Re: prop

Guylain<br />To bring RPMs down 800 rpms you need to go up 4 inches in pitch. This will give you more speed and fuel mileage but a little slower hole shot. Did someone put in a bigger motor?? Reason I ask is normally they change the outdrive gearing to keep pitch in the 17 to 21 range. A 25 pitch may be a little harder to find.
