I tested the new Solas 15/20R today
After hearing all the great numbers people were getting with the Riva Stage 2 kit I decided to test that prop.
The magic didn't work for me. I was only able to turn 8050 RPM's at 71 mph.
How are these skis with the Riva Stage 2 kit getting speeds of 75+ with this impeller? I want to know where the magic is

hulk what impeller are u running now? we just got our stage 2 kit its all most done and we will see about the 15/20R. u lost alot of rpms with it to big to turn or what?

I think the reason why Riva is using that prop is to bring the RPMs down below 8200 since they use the stock ECU with their stage 2 setup.

im running a repitched 14/19 impeller. Yes, the 15/20 killed my RPM's and speed.

It's also worth mentioning that the acceleration was not near as strong with the 15/20.

Could it be you get more top speed around 8000 since that is where the horsepower is ? With the ecu wouldn't it be running the ski at lower horsepower but better acceleration at the lows and mid's

Riva told me that they decided on the 15/20R after having reps from Solas meet at their FL test lake and try every different pitch known to man. This prop performed the best with THEIR Stage 2 Kit. Changing any of the parts in the kit might make for a new ball game. However with all the mods the Hulk has, you would think he would be able to turn it at a higher RPM than he got. His worked Solas 14/19 was done by PPG (right?)...so no one actualy knows what the pitch is at now....probably including them.
Everyone who uses the 15/20R with the full Stage 2 kit seems to be happy with the performance.

Told ya Jerry, Mark told me the 15-20 is too tall for our set up. Stage 3 people have to stick with the 14-19 set up.

Ok!!! Let me get this strait!!!
Riva states the 15/20 will do 75@ 8000-8100.
So if jerry is turning the same Rpm he sould be going the same speed.
I have the same prop on Andreas RXP. All I got was 74@ 8400.
This is a mistery
