This is actually my first encounter… heated with MAP gas and 3ft breaker bar. What do I do?! This is an FX-1 pump so I’m trying to salvage what I can. Unfortunately this impeller wasn’t bad before it spread out, just an old Skat-Trak 19-24 but take a look at my tool and the impeller… HELP!

Righty loosey, Lefty tighty?

I would weld something to the impeller to get ahold of it to turn. If you do it nicely you could probably even salvage the impeller. Then heat it a lot and then heat it more.

brapperdoodle · 2025-09-09T18:53:18-0400

Yep, it’s left hand thread like normal so I was pushing the correct direction for removal. Yeah I bet welding a large nut to it would be a good option! Unfortunately the inside of the impeller is pretty much stripped so I don’t know how much salvaging there will be

I just did this which, unknowingly, what @mikesx recommended.

Heat it hot. Spray PB Blaster into it.
Repeat.
Repeat.
Leave it alone and the next day it will come off easy peasy.

How to Remove 1994 SN SJ Drive Shaft?

I actually might have a sample bearing you could just have laying in the tool box yet

I have also had luck with heating, allowing to cool, then heating again, and repeating.

I had a wavejammer that ate rocks in a prior life, I took a skinny wheel and sliced it up to remove it from the shaft, but it was a soft aluminum one, might take quite a few wheels to get though that stainless one.

I have had a few on Seadoos that became permeantly attached , they ended up at the scrap yard .

So Brapp, what’s the job? Bearing replacement? Why you kicking this house of cards down the rabbit hole?

this is what i have done.

I like your style. Is that a Maxxx 1 piece ti pump?

mrfist9 · 2025-09-10T09:13:07-0400

That impeller tool is the worst. I'm borrowing my buddies currently which is the tool welded to a wrench

You honestly just need it in a vise, with a tool that doesn't warp and endless leverage

Watcon has a hardened extended one. A must have for 1 piece pumps.

Yes 160/83 maxx.

155’s are harder to unthread than 144’s, I gotta believe 160/165’s are even tougher yet. The rotational mass keeps going up on the same size thread! Do you have the Ti shaft ?

mikesx · 2025-09-10T10:28:09-0400

Sorry for the thread derail Brapp. If your goal is to salvage/reuse pump, shaft and prop I’d try taking a 5/8 threaded SS rod coupler ( outside flats 7/8) , bore the ID so it just slips over the shaft splines. Round off one end of it and slide the other end into the prop and weld it permanent. And give it a PB Blaster quench immediately after. At least you’ll have an external hex to work with that you can leave on the prop like the stock SJ props.

brapperdoodle · 2025-09-10T10:44:54-0400

Well, it’s hard to explain why I needed to remove this prop but I wanted my FX-1 pump back that was currently in another ski and this was the pump for that other ski. I wanted the impeller for my pump so I had to take it off to make that happen haha Ideally I will be able to salvage the driveshaft and housing but we will just have to see! I guess when I get the impeller off we will see if it’s salvageable? I bet not lol

Otherwise I will just buy the @waxhead pump conversion for the FX-1 and be done with this lil’ fella

Yeah those 122 pumps are sleeping beasts! If they’re working leave em be, other than that , I wouldn’t waste much time on it. The juice isn’t worth the squeeze with 122’s…
