Had a chance to put one of Norris's UHMW wear rings to the test last week. I was extremely impressed. A huge improvement in boat performance is realized with the first hit of the throttle. The boat turns much better ( I didn't think it would as it is a 16 deg bttm). It comes out of the hole quickly, and stays on plane at a much lower RPM. The product delivers on every thing as claimed. Norris is excellent to deal with , his turnaround time quick, and his product delivers as claimed, I'm sure it is the best money you can spend on a Sportjet. I had the wear ring installed because of an endorsement from another member of this forum and I highly recommend others give it a go. |

Do you ever get a chance to grind gravel with it......though I'm not suggesting that should be the goal? _________________ 17' Firefish Frenzy, 200 opti, 8 degree rock chewin' bottom. Fishin' Extreme

I've done a bit of gravel and sand through mine and haven't noticed any drop in performance as of yet. They really do make a difference on hole shot and handling of the boat.
I would suggest you get one Skinny with all the gravel you pump through yours The difference on turns will make you smile too. |

I don't know why there was so much controversy over this, I did the UHMW wear ring in both a 16' and 18' boat with 240's and it is an improvement over the stainless. They last a long time with plenty of trash pumped. The sportjets leave something to be desired though, I'll never go back to them. |

Hi Taiga;
Could you elaborate a little on the sport jet comment?
I'm thinking of selling the big boat and getting into something smaller.
Sport jet was kinda on my list.
Thanks

Depends on your boating style I guess, I found that the little pumps did not perform adequate for longer trips with the boat loaded and packing lots of fuel and gear, and the boats are typically smaller to begin with limiting space also. They are fine for going out with the family for a few hours though or playing. The 240 is a great engine, the optimax I would be wary of due to the oil requirements and cost. |

I have used the wear ring in my boat for the last two seasons and have gone on trips exceeding 200 miles with Duane Longfellow of RLS marine, and would recommend this wear ring to anyone running a sport jet. Better fuel mileage and less wear. Boat loaded with cheese, beer, peanut butter and crown. Probably going to add one to baby bud, I am tired of changing them in and out for racing.
Cheers to all,

I haqve to agree that Norris is top notch and his product increases performance.
I got a uhmw ring from Norris in May and the performance notice has been dramatic to say the least. I haven't posted a review on it because i haven't run my boat in the gravel as much as normal. I do know that i put 50 hrs on the insert and the motor is still hard to turn over out of the water on a hot day. That tells me the tolerances are still pretty good! stick the back end in the water and it loosens up. I have worn out 1 stainless insert with this boat and the stainless never had the performance this insert has no matter how tight i could get the tolerances on the stainless. _________________ Did anybody see that rock? |

Thanks for the input guys
I don't mean this to be a controversy, some are still skeptical so these first hand user reports are ones that I prefer if I'm going to use this product in the future.
Sounds like it has some duration pumping dirt..........that's what I'm looking for . _________________ 17' Firefish Frenzy, 200 opti, 8 degree rock chewin' bottom. Fishin' Extreme

Just to let you know we make them for the outboard jets also with even better results as you can shim them right to zero clearance. A 200 won't even spin out on take off. Norris and I have been working on this together. _________________ Right on Jesse, we got 256 rocks so far. Only 50 million more to go!!!!!! |

Yeah Dipper, I hear Ya!
The smaller boat is a little more forgiving.
It's not hard to become committed with the bigger boat.
Although Ive been places where it was no wider than my boat.
Great fishing and hunting boat but getting too big for this old fart

Thanks for all the good reviews on this product I wish that Mercury would look at this and make it a after market part then you racers could run in your boats
as far as gravel and sand goes we have a fellow here that I just took his pump apart and there is NO one that pumps more gravel and sand thru a pump than this guy does for all who knows him his name is Calvin Mcinnis
on the hour meter it shows 179 hrs and that is what this wear ring has one it as I put it in when the boat was brand new I measured the tolerance and it is now 35 thou. when I put it in it was 7 thou. a brand new
wear ring and impeller is has a clearance of 30 to 50 thou. depends on the housing and casting
and also one more note the water holes did not smear shut lol
for more info contact me at norkar@telus.net
lets go boating

Norris, is the current 35 thou clearance from impeller wear or does the UHMW wear, or is it a combination of the two? And how do you tighten it back up, new liner with smaller ID or build up the impeller?
Thanks. |

Just checked it and the wear ring wore about .010 and the trailing edge of the impeller was about .020 but the leading edge was only .005. We will just build up the impeller and cut the wear ring slightly larger (.020) and he will be back to new condition (.003-.005). Not bad for 187 hrs of abuse. _________________ Right on Jesse, we got 256 rocks so far. Only 50 million more to go!!!!!! |
