Have Riva S3 kit on 04RXP...Which is best prop/pitch to use for Closed course racing?
I have the true Riva stage 3 kit, have some issues with bottom end with my 15/19R skat-trak. sounds like cavitation.Slow out of the hole, im gonna double check for any air leaks in pump area..was curious if anyone has had luck with a certain prop or pitch for better bottom end. I have tried different rings from 83mm - 81mm in the venturi, not much difference for bottom power.I also have my solas stage 2 prop, has anyone tried that prop with the S3 setup?Thanks for the help.

Do you have a SS wear ring? If not you may want to check the condition of it. I would think that the 3 blade would be the best for CC racing because I hear it has the best acceleration and better hookup than the 4 blades.

I would think the 15/19r would be best for racing. A solas 15/20 seems to be better for top speed in some cases.

All these guys are right. 15/19r is great for the stuff you want

Definitely check out your wear ring and if you've got plastic do the upgrade to stainless AND get the solid front motor mount. This may be a bit expensive to do (almost $400) but will save you performance and future hassles.
