Plastic vs Stainless Wear Rings

[rgardner928]

So I learned today that they now make or have been making stainless wear rings.

Anyone have them? Seams like a great investment as you would never have to ever replace a wear ring again. But if the blade rubs, with plastic it can shave it down to fit. With stainless, its not a good outcome.

Also if you ever had to replace it. I'm sure its almost impossible to.

Can someone give feedback on stainless wear rings.

Most other PWC's use stainless wear rings but they have their issues also.
The stainless:
They typically have an aluminum housing and when used in saltwater the galvanic corrosion between the two cause the stainless to swell and contact the impeller damaging both. If a rock gets in it usually takes out both.
They can't touch the impeller.
They can last longer if nothing goes through them.
The Plastic/rubber:
Aren't affected by corrosion.
They can trim to fit the impeller.
They can allow things to pass through without damage.

I actually prefer the OEM seadoo ones and just replace them as needed and my impellers have been fine too.

Yep, I'm not warm on the idea of stainless b/c the impeller clearance isn't going to be as tight. It's not often you have to replace a wear ring unless there's something going through your pump, like rocks, sand, beer cans, nails and lumber?

I'm under the assumption the diameter isn't adjustable.
