Need to replace Carbon Ring?
I had a fit getting my drive shaft out, to get my engine aligned to the pump, I had to pretty much take out the engine.
Well anyway, I got it out then i knocked off the Support ring with a hammer cause rust or corrosion or something seized it.
I got looking at my carbon ring seal and saw a piece of it was chipped off.
And it was wearing very odd, probly due to me not aligning the engine and trying to ride it.
Well the ring is $54 and the support ring is $47, The support ring I have to measure to see if i bent it while trying to get it off. but i have a carbon ring from the gtx hull i took the engine from, I want to put this one on because it looks alot better and I don't want to buy a new one, at least now, with a lil anti seize, I can take my drive shaft out normally.
And If I did buy the SS wear ring, will that stop the plastic pumps from flexing? cause my wear ring is getting eaten alive, well could be from the alignment issue.
Note: This engine was taken out of a 03 supercharged hull and droped into a 02 GTX hull, it is the 02 pump assem and drive shaft but all engine components are the 03's.

I wouldn't do squat to the "plastic" 4 tec pump.. POS imo.
Either get the 04+ alum pump housing or just reuse
what you've got and replace the wear rings regularly.
Don't throw good money away to try to band aide a shitty part.

If I find one cheap I'll get it, but for now, i need to get it working right without it.
You would think there would be a better way to seal the hull than this...
like a sealed bearing?

sea doo used to use sealed bearings, others still do. they are available aftermarket also and can be retrofitted. carbon seal/accordion boot is alot cheaper to manufacture.
and the biggest reason they dont use a bearing seal is it needs constant maintenance, need to grease almost every ride, or it goes bad and is expensive and dificult to repair.
carbon seal is low maintenance and usually holds up for many hrs/yrs without problems. and is cheeper easier to repair when it does go bad.

i think if you fix your alignment / seal / driveline issues, your pump will stop chewing up wear rings so fast.
keep an eye out for an aluminum pump, it is the best solution for you.
by the time you buy a SS wear ring, you are more than halfway to an aluminum pump.
plus the SS ring wont work in your ski anyways.
a good setup driveline should not burn out a wear ring for 40-60 hrs. especially if you dont do WOT donuts all day long. it flexes under heavy load. if you are easy on throttle application, it will last.

what if you took the sealed bearing and put it in teh boot?
then there will be no strain on it by it trying to keep the drive shaft still from being mounted solid to the hull.
It will just go along for the ride, idk if i can find one that can handle high rpms. my luck ill try it and have the bearing come apart and then my engine will die for some reason and ill sink.

well I got it aligned today, got to late to try and put it back together, but I got looking at it and it was way off, just as you said, I did notice that the boot was vibrateing while it was running on the flush hose, i didnt think nothing of it at the time.
I made a red circle where the support ring was riding on the carbon seal, it was way off. I think the put more shims, I couldnt see without a flash light.

You might want to use a little Nevr Seize on the drive shaft when you install it. Just don't get any on the carbon seal... Ron
