When to replace wear ring?

[cobrajoe]

When held up to a bright light and looking thru the impeller housing assembly I can see on average a 1/32 inch gap around most of the 3 impeller blades and the wear ring.

Is this okay or is it a little to worn out and should be replaced (wear ring)?

Also if it does need replacing should I get OEM or I've seen one that is plastic but the inside is lined with stainless steel ?
It's sold thru Dennis Kirk and marketed for people that use their skis in salt water (which I do).

Thank You,
Joseph

Why would stainless steel be beter in saltwater than rubber/fiberglass?

I use oem wear rings.

I'm not sure myself, thats why I was asking.
I've seen it mentioned on several websites.
Must be some reason or they wouldn't be selling them. My guess is as good as yours at this point. [img]smile.gif[/img]

Here's one link

My manual says to check it with a feeler gauge. It says no more than .040

Well, for one thing, they say it will only fit into 140mm aluminum pumps, which takes away the stainless steel option for any sea doo pump made after 1995.

I really don't see any advantage for them anyway, especially in salt water.

You don’t say anything about you’re ski cavatating. I just replaced my wear ring, because of a cavitation issue. Wow what a difference, I don’t think my 99XPL has ever hooked up the way it does now. I’ve also noticed a top speed gain. My wear ring was really bad; I had no doubt it needed changing.

I can see an advantage in stainless steel in a plastic pump, It holds the thing round. In a alloy pump, the stock wear ring is better, They dont get the yamaha pump blisters and the corrosion growing behind them acts like an auto clearance adjuster! [ [img]smile.gif[/img] ]
