Superjet impeller removal, PLEASE HELP ME !!!

[manu]

I am trying to remove the stock impeller from my 05 Superjet. I tried to heat the impeller with a torch, and using an adjustable wrench but the impeller won't move!! It tried both way hitting the adjustable wrench with a hammer, and now I don't know what to do !
I went to Lowes and Home Depot with my pump to try to boxed wrench that will fit the impeller but nothing is big enough Do you know what wrench size do I need, so I can order it on the web. Also wich way should I turn to remove the impeller, red or blue arrow ?
Please help, give me any advice you have.
Thanks

Yes, I was already aware of this write up. The pb is that my stock impeller is not the same than the on in the write up. The impeller tool does not fit in my stock impeller. Also the wrench that I need to remove the impeller is bigger than 26mm, but I don't know what is the exact size. I would like to know the size needed so I can order a wrench on the web.

i use a large crescent wrench. if i have to i will use a cheater pipe on the wrench.

it will go, its thread locked on, just use a large all 16ths wrench, and turn, dont bend the shaft though, because it is so far from the pump, somethimes heating the impeller will do the trick, just keep it turning so the thread lock doesnt reset its self, possibly vise it closer to the pump, i keep spare drive shafts for removing purposes....this is my 2cents on this

Also people say that I have to turn clockwise to remove it. But clockwise depend wich way you look at it ! Can somebody look at the picture and tell me if it is the red or blue arrow.

Thanks!

Blue to loosen it.

AARGHH!! I can't remove it! I give up! :frown:
Anybody in Clearwater, FL area can do it for me if I bring you my pump ??

Is it blue? I thought it would be red, because when your prop spins itz counter clockwise, so therefore when the pump is spinning your prop keeps itself tight...
Correct me if I'm wrong..

Have you tried spraying some pb blaster on it, or soaking it in wd40??

Don't concentrate on the prop, instead look at the shaft.
It's the shaft that sets the prop into motion twisting inside the props hub.

Blue it is.

I have taken a stubborn prop to the local Yamaha dealer before, the mechanic had a 6 foot cheater bar and did it for free.

Definately use some heat. The stock prop is cast alloy so if you get it hot enough, it will expand enough to crack the threadlock that is on it.

I use a normal heat gun and rest it against the hub of the prop. Turn the prop around every few minutes so you get some nice even heat, then have a go at removing.

If you are looking down the long end of the shaft (non pump side) the prop will have to be turned clockwise to remove.

I was finally able to remove the impeller. Here is how I did it...
I removed a big bar from the closet and I stuck the cresent wrench inside one end. The impeller got loose right away without effort !

Today, I went to the beach to try out my newly installed Solas Concord 13/17 and Worx WR201 intake grate and I was impressed. I can feel a lot more power and the ski is easyer to manever.

Pardon my ignorance, but is it threaded to the drivshaft or splined like the Kawi's.

 

[Matt_E]

Threaded onto the driveshaft.

 

[Crab]

Not to knock Yamaha ( I will own one soon), but Kawi's are way easier.
