951 carb jetting?
Just changed my impeller from stock to a solas concord 15/20(new wear ring too) and now it's alot better for cruising but it won't rev past 6400rpm on the counter. Taking the stock air box off and replacing with filters.... What size jets should I be looking at fitting?? Any help appreciated
Ski is doing 56.4 on gps at these revs with r&d grate

The reason why your revs are way down is the 15/20 is too tall a prop to push(needs repitching)in a stock boat and the R@D intake grate pulls too much water into the pump and loads it too much which keeps revs down.The stock grate is better for rec riding.
Accelerator pump inactive.
95 low speed jets open 1.5 turn's
165 high speed jets both closed
2.0mm Needle and seat
spring rate to achieve 20 psi pop off (usually black one)most people dont use this one !
If Accelerator pumps are ACTIVE
Same set up as above but 87.5 low speed jets open 1.5 turn's.
Low speed jets
refer to the pop off chart to get the psi pop off.

+1 on SURFnTURF's recommendations....
He re-jetted my ski after he sourced Pro K's and outer wears for it and it was a day and night difference.
