EVERYONE loves to replace their wear ring because it's a "wear item" as I see noted all the time.
Yes, BRP typically uses a plastic wear ring. Regardless of the reason (there are many claims out there why that is), they can wear out over time.
Rocks, shells, sand, etc. Anything that goes through the pump will go in between the impeller and the wear ring. The impeller is made of stainless steel, the wear ring is made of plastic. The plastic can therefore be gauged, scratched, etc.
If you run your boat in shallow water with lots of pebbles (first of all, stop that, 3ft or more is recommended), then it's more likely you'll wear that ring out faster than most. A SINGLE rock sucking event can be reason to replace your wear ring. Many times, rocks will just go through the impeller. You may hear a short duration rattle and suddenly it stops. A sure sign you sucked a rock up but spit it out.
OK, so, when should you replace it? Well, when it's worn! The service manual indicates that when the gap between the impeller and the wear ring exceeds 0.35 mm (0.0138 in), it's time to replace it. This assumes it's not your impeller that's damaged. A new wear ring with good condition impeller should have a gap of 0 mm to 0.23 mm (0 in to .009 in).
Those gaps are very small because that clearance is what creates the right amount of pump pressure which accelerates your boat. If the gap is too big because of a gauge or scratches, then your boat doesn't create the same pressure. If that's the case, you can suffer loss of acceleration, loss of top speed and poor fuel economy.
My boat is a 2015 model. It's currently 2025 when I'm writing this. I have NEVER needed to replace the wear ring. Why? Because I'm very careful in shallow water and I'm very lucky that my waterways are pristine with no debris. I've lost zero top speed or acceleration. It does not "just wear" normally. It wears because you suck up stuff regularly or a one time event.
Wear rings are very cheap to replace. So if you're in doubt, just replace it. Look up Sea-Doo wear ring replacement videos. There are tons on YouTube.
