I have zero verification of this but stories always said that the MP/Solas three stage impellars were thinner than Kodiak impellars. I know they are about half the price so we all bought them. Never measured against a Kodiak however. I wonder if that would be the case with this impellar also. I know that Solas certainly knows how to make an impellar so I would expect it to work well. The price certainly is right.

So I contacted Marine Power and asked whether they have any performance stats for their impeller. Their answer: "Eric Shurman at Wetever has the most experience with this impeller 208-790-3222." I wonder if Mr. Shurman realizes that he is Marine Power's tech support and sales staff? Maybe I should have phrased the question differently, like "How did Marine Power come to the conclusion that this impeller is worth selling?"

I heard those guys are at WET EVER and there customers dont know about performance. Nobody is trying to copy/build boats that perform like the one's from there previously by employer.

They are fairly new and don't think they have been run in a ton of boats.. i know a guy that was running it in his 6.2 DI and worked really well with no nozzle insert. 4100 wot. They seem to be close in comparison to a 4.0 and seem to hook up really well. My other friend is testing one in his boat right now with his supercharged
6.0 liter and it seemed to work pretty well without a nozzle insert..4400 wot similiar numbers to a 4.0 with a nozzle insert. He is still doing some testing with it. I have had one in my hands and it is much lighter than a hamilton impeller. he could not run the 4.0 without the nozzle insert as it blew out bad. I will be testing in my boat with 6.2 DI soon. Prob not the impeller for an LSA but who knows at this point. I will post more after a little more testing is done. seems like a really nice impeller.

I hear only good about Wet Ever. But this response from Marine Power is difficult to digest. Like if I contacted Ford and asked them about their F-350, and their response was "Ask Mr. X who doesn't work for Ford. He knows all about the F-350." That just wouldn't make any sense.

Right, Hope you would not call Kentucky where the Ford F350 is assembled, I would assume you would call a dealer that sells F350's. http://marinepowerusa.com/dealers-distributors/ So they sent you to there dealer for info. :Drink:

But... so far as I'm aware, I can only buy a new Ford from a dealer, who mostly supplies information provided by the manufacturer. Like sales brochures, and maybe specialized tech information they received from the manufacturer.

In the case of the impeller, I can buy it directly from Marine Power via their website (that competes directly with their dealers), but apparently they have no information to supply. They have no sales brochure or tech information? However, there must be some basis for the design, and surely somebody from Marine Power or Solas tested it? Or do they offload this responsibility entirely onto each dealer?

Personally I would want to talk to the guys who had a hand in designing/testing it. I think it would be awesome to pick up the phone and talk to a Ford engineer in R&D.

That’s all subjective. When it comes to impellers wide open rpm on a known engine is reallly the only way to compare impellers to one another.

What is your wide open rpm?

4500-4600.
More importantly it doesn't cavitate and stays hooked up out of the hole.

Ok so I tested the 6.2 DI hooked up to all three impellers at the lake .. no white water yet.. here is what they did for me.
the 3.4t slipped /blewout from a dead stop and from 1500 to 2000 . I had to get off throttle and back in it.. once it hooked up it ran strong 4300 wot and 47mph
the 4.0t slipped from a dead stop but didn't blow completely out. It ran 4000 wot and 45 mph
the solas impeller didn't slip at all from a dead stop. hooked up completely 4150 to 4200 wot at 45 mph
3.4 t cruise was 3100 to 3200 3/4 tank of fuel and 2 200 lb guys and a 70 lb lab plus all my regular crap..
4.0 t cruise was around 3000 same
solas cruise was around 3000 same
no nozzle insert 22ft hcm 3000ft elevation
solas was a clear winner for me with my setup. white water next.

Does Solas make a 3.4 impeller?

That is superior information.

We hope for wonderful white water results. When I added an inducer to my Berkeley setup I was hopeful it might help a little bit. Instead it was miraculous. I could park myself in the worst froth, punch it, and no problems.

Visually, is there a general difference between the Solas and Hamiltons?

As of now they only make the (turbo impeller ) Which seems to be right in the middle of 3.4t and 4.0 t . loose a little rpm or gain a little at wot but the big thing is the slipping or blow out to me. I believe it will do good in white water as the guys that I know that have tried it were very pleased. Good to have options ..
Here are a couple of pics of the solas and a 3.4t. Solas is quite a bit lighter also. :Drink:

The main difference I see is the Solas leading edge is more perpendicular to the flow. And the lower blade is maybe a bit longer.
