Great news! The new 4 blade impeller for the 2021 RXP-X is now available.

Isn't that backwards?

It seems every few months a new magical impeller gets announced with lots of hype and then reality kicks in. Stock '21+ impeller seems to be winning no matter whats thrown at it.

I have lots of hype sitting on my bench. I have both of the new four blades and need to try sometime...but I did try the 15/25r 159 3 blade. It was impressive. It it got me another 2mph over my perfectly trued/balanced/race finished 19 PX impeller that skat did for me. I basically told them make this thing perfect and they did. I was already pushing 8700ish rpm and that put me up in the 8900 rpm range on a custom stage 4 setup. I don't really want to run that high rpm...but it was faster. My ski is bone stock again but with no limiter so i'm curious where it will be with that prop rpm wise...soon as this cold FL weather goes away I'll find out.

That's a 4 blade no?

I had impros pitch me a 15/21 into 15/24 and can't say I saw much difference. Maybe I'll give it another try before I sell this ski.

98% sure it's a 3 blade, not sure why i'm questioning it all of a sudden, been a while since i messed with it. They compare it someone to the 13/18 3 blade but better top speed yet similar acceleration, which less good then the 161 stock impeller. I couldn't really tell difference in but dyno, I'd have to run them back to back with the vbox. I'm mostly going to keep using it, I do want to try the 2 new four blades I have. All the people I know going real fast seem to be running 159 props. I always worry about the stuffing but It didn't stuff around 86-87 dash with the that prop...so I guess i'm good

I'll take that 2% bet

Dang..I'm now 2% sure, I think you are correct from the not great pics I came up with. Not sure why i was so sure it was a 3 blade. Weird thing is it isn't in the 2022 Solas catalog. Special thing I guess Riva and Solas developed.

Yeah those 15/25’s are 4 blade. I was using one most of last season

What was your experience? Ski/rpm/ top speed?

Does the 2021+ impeller the same of a Solas 4 blade or they are different ?

GTR.85 dash@9100. Switched to a Sxx-14/19 and now 82 dash@8400. Gonna go with a bigger wheel.

Those numbers look a little weird, 15/25 at that RPM should be faster and curious as to your setup to be able to spin it that high. Is your GTR a 4Tec or Ace motor?
