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

[Green Hulk]

This has been in the works for quite some time and these are now in stock for immediate shipping and offered at a discounted price in the GreenHulk Store.
I’m told that this new design gives a 2 mph increase over a stock pitched impeller, plus better acceleration and hookup. This was designed specifically for use with the 2021+ RXP-X. We will know soon how well it works on other 300 Models, such as the RXT-X and older RXP-X skis.

Stay tuned to the GreenHulk Garage YouTube channel as we will be doing a back to back to back test on our 2021 RXP-X with our V-box equipment comparing the stock, 13/18 and this new 13/15 4 blade impeller.

Just got a 13/16. Maybe it will be my winter prop...

I guess Dino was right. Damn 2mph that is a significant improvement over stock which doesn't suck.

Might want to mention it is a Solas impeller.

Looks like I may pitch my extra stock impeller based off this. 4 blades, check.

The current GH store Stage 1 kit lists a Solas 13/18. Will this new 4 blade replace the 13/18 in the kit?
I guess if the new prop is a 13/15, in order to go faster, the RPMs will be higher. What is the RPM target of this new prop and are you still running the 8500 tune?

A 13/15 4 blade should turn similar rpms to a 13/18 3 blade
