Hard to tell for sure by photos, it also appears that the Solas has a smaller wizard cone on the entry to the turbo-inducer. If true, it would mean more blade surface area to grab water for the main blade.

What ever happened to Hammyman? He was warning us all about counterfeit impellers as I recall... hunter_134) Oh, that's right Hamilton jet outed him as a counterfeit... :Laugh1: They look good! I'd try one out :Drink:

Haha, I remember him!! He was telling me how I shouldn't have my 4.0t tightened up and repitched, and the stock impeller was just fine for my boat, even tho my stock impeller would rabidly froth at WOT without the boat moving :/

(Yup, as I bear witness, you did) :p

Would have been interesting to see how this Solas impeller would have done in my boat prior to the Scott swap, tho I still would have wanted at least a 4.0 pitch.

Anybody know how long this impeller has been available? My guess is quite a while, but that's just a guess.

I think they showed up last summer. So not very long. Saw one in Clarkston in late July. I don't think they had been available very long before that.

I ran the impeller in a little white water today over at king hill. I had 4 people, dog and couple of coolers and 3/4 tank of fuel. It worked great.. didn't notice any cavitation in what little white water there is over there. I didn't run peg leg as the flow was only around 7k. Maybe next week if flows come up. We did play around in pilgrim some in the rollers and hooked up great every time. The push felt just like the 4.0t but with 150 more rpm and no slip. stock nozzle.
My friend had one in his supercharged 6.0 today also and said it was working great. no nozzle insert also.

Hello everyone from Russia!

I am also working on a 212T 3.4Kw impeller, I want to scale and adapt it for my water jets. I printed a model with wax, now I want to cast it from metal and give it to my guys for testing with HJ213, the original is scanned, the CAD model is made and increased by% shrinkage of the metal in the mold, the casters have to do ...

I've had one from Eric since last fall but was unable to get any testing done until this spring.
My setup 23ft Bentz 440 raptor have run 2.9t, 3.4t stock and jetco grates, and currently have a nozzle I can change inserts from 103mm to 107mm. My nozzle without inserts is 111mm
1st test setup MP inpeller with a stock nozzle full of fuel 7 people 1 cooler and a dog. Dead stop take off hooked up without any slip stayed hooked up all the way to 4050rpm
2nd test same setup stopping in frothy WW as close to stopping as I could. Again full throttle, hooked up without slipping and stayed hooked up, I could stay at WOT due to climbing up out of the rapid. But never slipped out. RPM 4000
3rd test headed down river 12 people 5 dogs and 1 cooler. Taking off in smooth water no rapids or WW. It took me a while to get on plane but once I did it held. Had to run at 3600 or so to stay WOT was 3950rpm
4th test put my nozzle back on and ran it without any inserts. Stock Nozzle is 108 to 109 depending on who's nozzle you measure. My nozzle without any inserts measured 111.5mm. This test was done on a different day without as many people and about 1/2 tank of fuel. From a dead stop with 3 people 1 dog and a cooler it shot out of hole no spin out and ran to 4050 rpm. I did not get to any WW that day due to time constraints.

Initial impression: This impeller appears to solve my spinning out problem when taking off and appears to negate spinning out in WW. My 3.4t with the stock nozzle still spun out and my top end RPM not much different. With inserts and my stock 3.4t I was able to get rid of the spin out but the boat was not as impressive out of the hole and it didn't appear to be able to carry as big of a load. MY 2.9t spun out all over the place by my top RPM settled in at 4300 or so. I believe with this new impeller and either going with the stock nozzle or my nozzle without inserts my boat is running much better. I'm very happy with it. I did not pay attention or take my GPS to figure out top speed. My concern for my application was being able to pack a load and stay hooked up from a stop and in WW which this setup did. The next time I get to the river I till experiment with my inserts and track top speed with the gps. All testing was done in hells canyon between the landing and rush creek.

That is superb info. I will try, though probably not until after the primary boating season.

Hey Linehand,
Any additional information would be much appreciated. My LSA/212 does pretty good with a 4.1 impeller with WOT about 4500 in hell’s canyon. Real heavy loads can be troublesome and oddly enough light loads too. There’s like a sweet spot for weight, and it seems like the sweet spot must give the pump a teeny bit of additional water loading pressure or something. Forgive me if you already shared this information and I missed it. Thanks

-size and make of boat?
-loading?
-elevation?
-any other pump work?

Update on the solas impeller... Ran the salmon yesterday at around 17500. Performance was awesome in all aspects of the river. It hooked up every time. Very happy with the performance. I know another guy that changed out a 4.2 to a solas and he really knows boats as he owns a major boat shop. He is running a
built 454 with 550 ft lbs of torque and says it is working great and no nozzle insert. (stock nozzle). No blow out .

The Solas is a around a 3.4T. Quite a difference compared to a 4.2. Do you know what his WOT is now?

He said that his wot is 4400 on the salmon. I am not sure what it was with the 4.2 but he had to run a nozzle insert.. (103mm) I believe. I tried a 3.4t and a 4.0t in my boat and I felt the solas was closer to the 4.0t . Solas was about 100 to 150 rpms higher than the 4.0 which felt better in my boat. You could prob. call WWM Repair and talk to Bill about the solas. Maybe solas will come out with another impeller with a little more pitch to run with the supercharged motors.
