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.

159 or 161mm ?

161

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

It doesn't work like that.

[jeff24680]

So explain how it works? I am not familiar with the complete picture of impellers. The OEM is 4 blades, I have an extra OEM one that I want to send out for work. If I pitch it to match this one which is also 4 blades why shouldn't results be similar?

Does the actual shape of the blades come into play? Educate me!

Blade shape, blade cup, blade over lap, blade thickness and obviously pitch(angle of blade) all play major roles. Along with diameter of prop, their are really ALOT of variables.

This is good info. Makes my choice tougher, but good info.

If I purchase this can I pick it up at Mudbug?
