    Do you mean Solas DF 13/22R? If so, I should have mine some time this week.

    Updates to follow.

    Solas has had those props listed for awhile now as recommendations. But, as far as i know they don't exist in real life.

    Jerry and shobiz had the gpr 14/20 dynafly's drilled/tapped by Riva/skat out to accept the larger sho drive shaft and re-pitched to 14/21.

    His results are somewhere in his build up thread. I believe he picked up some speed top end. But, he was spinning it out of the hole. Then again he's also pushing 350+hp.

    He has since moved up to a 158mm pump and possibly now a 160mm. He's the person you want to talk to about the props.

    I think most of us are using the 13/24-13/25 R&D/skat props on the powershot/10-11lb wheel setups.

    Solas has released the 13/22r(tommy measured it as 13/21) It seems like a good prop for a stage 1. But, i don't think it has enough trailing edge for a stage 2.

    I'd be interested to see it re-pitched to 13/24 and run on a stage 2 ski compared to the skat props.

    I'm running the DF 13/22R with all of the Stage 1 mods minus a Ride plate. I'm going to try out a R&D rideplate modified by Jim for speed and possibly the new Riva adjustable nozzle. For next spring, I plan on upgrading to a B1 wheel, Riva cooler and Riva ECU (crossing fingers). At that point, I will probably get my 13/22 re-pitched instead of buying another one.

    I need someone llighter to ride my ski, as I still think mine is a turd with all of the stage 1 mods. It goes faster by the GPS but doesn't feel faster to me.

    I think that the riva adjustable reduction nozzle is going to be very helpful for this....since its such a pain to change the prop...

    I'm not sure if those are shipping yet. As far as I know, the only one on the market is the 13/22R DF sold by Riva. I have the 13/22r but haven't installed it yet since it probably won't be enough pitch for my setup until I get the adjustable nozzle...hopefully next week.

    Thumbs up prop testing 15/22R

    The riva 13/22r which I have checks 13/21 on my three gauges. With a air filter mod, exhaust mod, and the ribbon removed and a sleeve instaled to replace the ribbon( Stage 1) I saw 7720 rpm's in 90+ degree air temp (out of box prop) . I re pitched my prop to a true 13/22r and now on a 95+ degree day I am turning 7620. which should give me a little room to go a few more rpm's when the temps get lower and the humidity get down from the 90%+ it was when I tested. IMO this is a much better impeller than the oem one. While this prop is has not gotten enough pitch for a ski with a aftermarket boost wheel on the SC it sure works good with the general mods ( intake, air filter, exhaust) I also gained 1-1.5 mph compaired to my re pitched oem impeller under the same rpm's and riding conditions. These ski's (SHO,FZR,FZS) to get the best performance from them the impeller pitch " MUST" be matched to the modifications you make to your ski to get the rpm's correct. If you miss the correct rpm's by 200 or more high or low your results will be very dissapointing to you! I hope this information will help you! Tommy Jordan

    Yes these are available!... and there a few out there---
    As soon as i get a chance, I will measure both impellers ( EXACTLY ) and see what we come up with.

    The title of this post didnt mention the RIVA 13/22.... just want to keep the post on track about the 14/21 & 15/22
