Anyone try a Twin Drive Impeller System?

[Quinc]

"
The new Twin Drive technology is here. Skat-Trak introduces its newest innovation in impeller technology for PWC. The main Drive and Inducer impellers will increase the performance of your watercraft weather you have a stock PWC or a full-blown super stock racer. Adding blade surface area to your impeller will increase acceleration performance. Pre loading the inlet with the inducer impeller may increase top speed. The combination of the Twin Drive will give you performance gains across the board. Still the industry leader in PWC impeller and jet pump systems, Skat-Trak is always one step ahead of the competition.

They've had similar impellers for a while for the bigger couches.
I'd like to know what watercraft weather this will improve; less rain? warmer winters?...

Blake had one in his first freak. I don't think it really did anything.

I saw a similar set at World Finals a few years back. They said it was mainly for couch's too. I haven't heard anything about a stand up application but secrets are short lived in our small family, since its been out for a while, if it worked, I'm sure it would be all the rage

They use those in couches for Flyboards and they work awesome.

^^yea ive only heard them really being used with flyboard applications

all the jet sprint boats use multi stage pumps. so much more efficient.

I seem to remember Taylor Curtis trying one a couple years ago (and putting it up for sale REALLY fast).

So those extra blades help keep the stress on the driveline lower at slower speeds for the couches or something? How does a prop like this work and what for? lol

 

[fast superjet chase]

They work great in a 1100 sxr helps slow the bottom end hit down and keeps it hooked up in the rough

You'd think it would help, but maybe they hurt bottom end for stand ups due to the extra work required to spin more blades? More surface area/mass = more friction = more work to spin. It says it increases acceleration though, probably due to higher pressure. I guess it depends on if the higher pressure out weighs the higher friction. Somebody try one and tell us!

i heard main problem was weight
