Thought I'd share a picture of the wear rings I made for a customer this week.

Spring is around the corner, don't let a plastic grooved up ring slow you down!

Rebuildable aluminum ring lasts forever, and you don't have to beat it in or out.  ;D

Tom,  Received the new wear ring yesterday.  Installed immediately, it fit like a glove, a snug fit with a little pressure on two sides. Can't wait to install the pump and give her a run. \./8

Thanks, John

Am based in Alaska with 5 mokais. Going through plastic sleeves each trip. Factory seems hesitant to offer aluminum sleeves due to concern over the possible damage to blades. Your thoughts please?

I've sold hundreds of my aluminum wear rings, and have used them exclusively in my boats since I started making them. No damage to the blades have been seen or reported to date as a result. Just a savings of never having to buy a wear ring again. Pay $28 a pop for two weeks worth of use, or get mine and it will last forever only needing to be resurfaced with JB Marine Epoxy when needed. The wear ring comes with the first package of JB Marine, which will last at least 10 times to resurface. Pays for itself and then some.  \./8

Hello Boris,
Under certain conditions, blades can be damaged with either ring.  I used the factory rings for years and now the aluminum.  Aluminum is much better and cheaper.  No real world difference regarding danger to blades.

Still in catch-up mode...
What exactly is the mechanism that wears the wear ring?
Are the pump blades grinding on it, or is it debris that gets sucked in and wedges itself between the blades and the ring?

The blades do not touch the ring, the tighter the clearance though the more efficient the impeller will be. The wear occurs when sand, mud etc.. pass through and wedges in that clearance like you described. If you are in clean water and never suck up anything, then no wear ring would wear out.

How can you tell it's time to re surface or replace the wear ring ?

You should never need to replace the one I make, part of the reason I came up with it, resurface when you notice a loss of speed or an increase in rpm that isn't debris related. By sight you would notice a groove forming in the ring where the impeller spins. Watch my video on resurfacing to see how that's done. http://www.improvingyourmokai.com/index.php/topic,200.0.html
