Impellers other than factory but factory pitch, Which to buy?

[jcyamaharider]

I am looking to replace my impellers with a different brand because frankly the OEM ones are not meeting my expectations. Only 70 hours of use and they are already wore down to out of spec tolerance due to sand or whatever other reason. I know they are probably the best as @swatski has done extensive testing, but I am looking for impellers that are more durable. I had solas on my last boat that I purchased from impros and i loved them. What I don't want to do is buy impellers and then have to take them out for re pitching. I have heard of a couple of people having to do this and I can't have the down time. So what have you purchased and how did it work. High altitude is not an issue for us.

TIA

I'm in Mo and still want to try the 6cw=r1321-01-00 on our '18 242x

 

[jcyamaharider]

That one will still wear away like the factory ones I have. I am looking for more material. I may just go ahead and buy another stock set for right now. Looks like we will not be river boating anyways.

Watching.
Personally, I still want to try the 6CW (which is the single engine OEM), I actually have one sitting on the shelf there is just never good time to do it, plus I'm really okay right now as far as performance.
I would not go back to Solas unless you try it out first and tell us what you think. They are good for speed, but not much else - in my experience. Skats are great as far as support - the company guy (Glenn?) is super helpful, and passionate about impellers. But that means sending those back and forth.

Hah, yes - if it is about sturdiness the OEMs lose every time, they are flimsy no doubt.
Except they don't tend to explode as 1.8 Solas do! lol

I am in this predicament myself at the moment. Although I don't think my OEM are worn out of spec, but I am st high altitude and I think I'm going to need a little more low end push to get up on plane with the transom bag strapped to my arse...

@Williamsone46 reported better performance for the 242X and +700 RPM at this altitude.

Both of which I think I can use. The crappy part is, when I called my dealer about them today he didn't seem to accommodating to me when discussing the 6cw's as an option... he more or less just told me to call Impros. I just dot want to go with solas from Impros because the dealer is to busy to accommodate me.

I know folks are using the Luck 13 cones too, but something is telling me to start with the impellers first. I'm just thinking that $600 is a lot to spend in cones, when the impeller choice may be the bigger factor... maybe I'm wrong???

I'm thinking of contacting Impros tomorrow to see what they have to say or offer.

Sorry I don't have more helpful advice to contribute to your question @jcyamaharider.

I am still on the fence, and for what it is worth I am already running L13 pump cones so I would agree that impellers would be the better choice right now. I may give imports a shout tomorrow.

 

[SamCF]

Ask Glenn about a custom twin prop.

@jcyamaharider, maybe I'll end up with a spare pair of near pristine stock impellers?

 

[swatski]

Ask Glenn about a custom twin prop.

Well, not in the N/As...
There were at least two guys who ran those and loved them, one is using them for flyboarding, the other for ocean crossings in Hawaii - both report epic thrust and hole shot, but abysmal top speed.
With SC engines it is different.

I talked to Glenn at Impros and I'm a little bit torn. He's mentioned that from what I described, as far as my RPMs and elevation, he doubts my impellers were ever pitched for altitude. Which he says is unusual due to the fact he's been pitching impellers 50 at a time for my dealer for the past 8 years... but he doesn't know what boats they've been putting them on and was unaware if they were putting the 6cw's from the 190's on the 242x boats.
So, he's willing to hook me up with some elevation pitched 6cw's for $385 each, he'd also be very interested in the feedback on their performance. All that said, he thinks pitching my stock impellers appropriately might be extremely helpful too and save me several hundred dollars. So...? I'm curious, I just don't know if I'm $770 dollars curious...
Glenn is awesome either way.

The guy is knowledgable and passionate. He is not cheap but he does what he says. And he does not cut any corners, his reworked impelelrs meet all tolerances.
I may do some testing with him on the 6CWs later in the season, so let's keep in touch about this project.
It may even be helpful to you - I think I have a pretty good idea now of altitude differences having just done some 50 awesome hours on LP!
(mostly WOT, lol)

And therein lies the challenge! Hard to find a good "all around" impeller or your taking hole-shot over top end or vice versa. Where is that magical silver bullet?

 

[jcyamaharider]

What I am looking for is just a regular impeller that will not wear out of tolerance by just boating in our sand rich river. Those 6CW impellers are $196 each on yamaha sports plaza. I may try those and I have a lead on some Solas impellers I can try.

Yeah, I trust him to get me good results whatever the case. The one report on use of the 6cw on the 242X was positive, and their reasoning was altitude and added weight of the X features... so that's really the route I want to explore... also I can keep running my stock impellers all the while, which might make the added costs worthwhile?

Apparently they're one of the only options for impellers with that type of overlap. He did tell me that there was a Solas option, but it was for a larger diameter. They'd grind it to fit and then have a fair amount of pitching to do from there.

The answer for @jcyamaharider may be a combination of Solas impellers of whatever flavor you think will meet your needs and stainless wear rings.

Right on!
To make everything shine a slightly different pitch on STRB and PORT are also required...

At the end if my past experience is any guide, unless one is really into this for the sake of it, it may be that a new OEM at $200 every now and then is the way to go (at no elevation/sea level).

So, I pulled the trigger on a pair of 6cw's I figured it was worth it to keep my stock imps to use while Glenn does his thing rather than be without for any period of time. So, we'll see how this goes... ? I'll be sure to report.

I'm at 3000ft and had to order OEM replacements for my AR240 today. Would I be better off changing the order to the 6CW's. Primary goal being top speed.

Edit - I havent even taken the boat out on the water yet, I bought it last week and took it to Yamaha for inspection and they suggested replacement.

It's a bit unknown, but my guess would be not if you're looking for top speed. Top speed will probably best be obtained thru re-pitched OEM and possibly the addition of the Lucky 13 cones. Solas impellers may trump the OEM in attaining top speed.

I'll let everyone know what the 6cw's do for me at 4,500 ft if I every manage to get a hold of Glenn at Impros again... he took my order info a week ago and said he would get it rolling but I didn't have my card with me at the time to pay him. I've tried numerous times to get thru since. So I'm hoping he's ordered them and is just waiting for them to come in prior to contacting me again...?

Must be busy with the transition? Glenn (Perry) that used to be at tech@skat-trak.com apparently bought out David of the original Impros. Which would not be bad since I've heard he actually trained David guy in the first place.

Keep us posted! IIRC Glenn likes to talk over the phone more than answering emails, lol.
