Does anyone know anything about the "Ultimate" wear rings they show at Hi-TechPerformance.com? In the pictures they are orange, which makes me think that they're some kind plastic, maybe Teflon or something like that. I'm just curious, personally I use the bronze ones. Just want to see what you guys think or know about them.

I will never use anything but the Ultimate wear ring. As long as you never run them dry, they work!!

I hear this a lot, but I am relatively new to jet boats. What exactly is "hole shot"?

That makes much more sense now. I thought it was how smoothly the water flowed through the pump.
Thanks man.



Lots of helpful info here. But my question still hasn't been answered. What are they made of? Plastic? Why are they orange?

I'm not actually in the market to buy one right now. I have a brand new bronze one right now. I just saw a picture of one today and got curious about them, so I started this thread. But, next time I need a new ring I will probably get one. They act like an actual wear ring, right? The ring gets worn down instead of the impeller, right? Because I just run an aluminum impeller. Now I know more about them so I'm not as weary about buying one, thanks everyone. But keep it going, every little bit I can find out about them helps.

They are Polyurethane, RUBBER, not plastic. You know what bowling balls ans roller-skate/skateboard wheels are made of? Polyurethane.

Been running them for 19 years now (first one still sealed very well after 16 years, replaced it when replaced the Al. impeller with bronze).

I also have no plans to run anything else.

At least it has got out that people figured it out not to run it dry or else. rondane
You had to find this out the hard way, didn't ya.

I on the other hansd listened when Duane told me to NEVER run it dry, even for a few seconds.


HawianJet, you will net ever find a tighter seal than a UWR, because all metal wear rings are spaced away from the metal impeller some distance, while the UWR literally rubs against it, making a nearly 0-clearance fit, with far less contact friction than any 2 pieces of metal.

Even though it may look similar to plastic, there is no plastic content in the Ultimate Wear Ring. It is made out of upper echelon urethane polymers that have been vacuum boiled, baked at a controlled temp for a period of time, and them ran through a cyrogenic anile process. This process produces a product that has no measurable cofficient of friction to water, as metal wear rings do. This allows the pump to spin freely and use more HP for thrust. This product also produces a much better seal than metal does. It is also a very abraision resistant material.

To an extent, yes. On Aluminum, both will wear somewhat. The thing is, get a little grit in there occasionally (a bunch of sand will still not do you ANY good) and the wear ring is basically "self-healing". The scoring in it "dents" the material more than "cuts" it, and it then presses back out to normal position, thereby somewhat "repairing" the damage from some sand.

That's more like it! This is the information I was looking for! I am very familiar with polyurethane in skate board wheels, roller coaster wheels, ect. It is a great material, hard but also flexible. A couple of months ago I parted out one of my extra pumps, and the impeller and bronze ring that I pulled out of it were completely F'd up, the impeller was worn so thin that it had a crack going almost all the way around the base. You guys got me sold on the UWR next time I replace my wear ring. Although now might also be a good time to do it since my pump is completely disassembled. But at $124 a pop, I don't know, seems a little high for basically a giant skate board wheel. I just bought a Barry Grant Demon carb, so that's a little high at this time.

Thanks everyone for all the information. Keep it up. Need all the help I can get.

Ummmmmmm,
Why do you like them then????
didnt know i had to explain in detail.i like the s.o.b.s;)that says enough.


i have found with them they get eat up with little grooves if you get dirt,chat,sand ect.pretty quick,but they still seal very well.and the plus side is it doesnt affect the surface of the impeller wear ring land.it still looks new and the wear ring takes the abuse.

i have run mine dry out of the water.put my garden hose in the pump and ran it,the only signs i have found is alittle burn marks hear and there.not sayong you should try this i just like to fire my boat up once and awhile out of the water.:)hand

I run one and will NEVER go back to a normal wearing. I gained a killer holeshot and it was too easy to install. I dont miss pounding in the old style wearings.

i've ran all types, and i personally like bronze. i can't tell any difference in holeshot between a nice fitting shouldered bronze and a u.w.r.. i've gotta get a bigger impellor soon and i'll prob buy a u.w.r. for the simple fact they are a straight ass breeze to install and set clearence on. i'm currently runnin a fresh standard bronze ring on a b-cut and have no holeshot cavitation issues, as soon as the boat has a set, it goes.
