Speed newbie ultra 300x
I want to push the speed limits on my Ultra 300x this summer. Any suggestions on impeller or a basic mod to do so?
Plan to use it in open water this May, but most of my use last summer was lakes, towing skiiers, kids. I can switch back an impeller before towing if necessary (unclear at this point if I'd risk hurting machine with a speed impeller on it while towing)
Any thoughts muchos appreciatos !

Many choose to install the SCOM. Personally, I do not feel it is neccessary if the the Ski is just being ridden recreationally (i.e., you will use alot more fuel).
My reccommendation is to just leave it stock and enjoy it the way it is. This Ski provides alot of "thril" just the way it is. JB

Buying a new impeller w/o a SCOM won't give you much if any more speed. Like JB said, it gives plenty of thrill the way it is. For towing, the stock setup does just fine. Buying a new impeller alone would probably just be a waste of money. To see much of an improvement, get the SCOM and a 14/21 pitch impeller. But do realize, each mod comes with some sort of sacrifice.

Thanks a lot guys. What is SCOM?
ive seen footage of peeps catching 106mph on an ultra 300x like mine but I am sure there are mods made.
any idea how they achieve those crazy speeds?

Just FYI, this will void your warranty.
Like dave said, 106 is kmh even though that would be badass.

You can actually purchase the SCOM from the forums online store also and in doing so get a 10% discount on select Riva and R&D parts including the SCOM using the coupon code GREENHULK
Here is the link to the Riva SCOM
Here is the R&D SCOM
If you would like the Impeller also here is the one I would recommend

Thanks a lot you guys. Might go the SCOM upgrade route.
Ha....wow...106Kph not mph. Bet you're right !
Do love this machine.
