New Impros Hooker Impeller for Yamaha

[IMPROS]

We've been working on a new impeller for our Freestyle riders on a Yamaha SJ and Blaster and came up with this one.

We call her the "Hooker" because she "hooks up" so well.
Designed around maximizing pump efficiency and bottom end, this is a new radial edge design, large hub (75mm), and is set back 7mm (4mm further than we can go with a small hub impeller).
Pitch options are:
9/15 (for anything from a stock 701 to a strong limited set up)
10/16 (for the more healthy version of a limited with porting, big carbs, etc)
11/17 (for maximum hook up and added HP)

Here's a couple amateur shots by me of the new Hooker...

Designed with a nice steep root angle to load the pump well. Some might say they sound too low and may spin, or burn outta the hole, but the other geometric changes made to the Hooker reduce the chance of spinning.

They are designed for Freestyle, and Freeriding, although some of our riders are using them for closed course racing as well with great results. To give you an idea of the load on the engine, the 9/15 loads similar to the custom Solas 13/15 that we do. Further set-back increases the pump efficiency, along with the larger hub and blade length. I'm really happy with how this impeller works compared to the other popular repitched versions that have become so popular. Don't get me wrong, they work excellent, this one just works better, and gives the ski more "pop".

Retail price is $249.99, and comes with an impeller tool and nose seal.

looks/sounds sweet... need any more test subjects? :wavey:

I'll definately put this at the top of my list when it comes time to change my impeller this summer.

damn I would love to get one of these but I have a gift certificate for a prop from skat-trak.

Will you give trade in value on one of your 13/15 cutback solas props?

 

[waterfreak]

any suggestion for a o8 sj with a 5mm lamey stroker?

 

[IMPROS]

King, if you're interested, PM or email me and we can work it out with the cert. you have...

All impellers have a value here. Depending on the condition, we can definately apply credit toward another impeller. We take trades all the time.

[IMPROS]

What else are you running on your 08? Pipe, carbs, ignition? Do you have it together yet and tested with the stock impeller? Let me know. I'd probably go 10/16, but let me know ok.

Dave... I just sent in my impeller to be re conditioned... but now since I see that you take trades, I might see what this hooker is all about.

Make sure you call me after it gets here and remind me what you're thinking about doing. Our turnaround time has been 1-2 days, so it would be best to try to catch it while it's here...
Thanks

I got mine today. i went with the 11/17. only rode it for 5 mintues. but i definitly noticed it down bottom. i was launching alot more off of my set up wakes. there is no slip or hesitation at all. I will comment more after tomorrows ridign. great product. we all know dave is a pleasure to work with. thanks dave for getting it to me for the weeked like you said. thanks again, Mike

 

[Big Kahuna]

Dave, are you manufacturing these yourself, or taking a Solas or Skat and modifiying?

 

[Mouthfulloflake]

IM curious about that too ^^^^

also, how do the pitches correlate to a solas concord 13/16?

I still like my 12/15 you made me a few years back, pitch wise, I guess that would be similar to the 9/15 hooker?

can you pitch them any lower than 9/15 or is it even needed?

There ya go.

 

[Mouthfulloflake]

I read that.

it also says its similar in pump loading to a 13/15.

I run a 12/15, so I was asking about going even lower.

thanks though!

Hey guys,
We're not a foundry, so we're having them investment cast to our specifications. Blade length, pitch, positioning in the pump is all done in the manufacturing process rather than altering one after the fact, and specific to what we determined after relentless testing against our most popular Yamaha impellers. I'm very happy with how they're working. We still sell the popular Skats and Solas Yamaha impellers, but I do like these better in almost all cases.

If you like the 12/15, the 9/15 will produce better "pop", and load the pump better. It's set back further, and the pitch and hub design give it a much better, responsive feel.
The 13/16 Concord or Freeride is similar in load to the 10/16 Hooker.

We can go lower than the 9/15, but we kept it here, becuase it's a great pitch for even a stock 701.

Thanks
David

Thanks Dave.

thats really a cool concept, making them as you wish, instead of altering after the fact.

There is always something to spend money on!!!!
Very tempting.
