hey Mark have talked with you and you seem like a straight shooter . just trying to keep it real . plastic has some merits but nosed up against a log with the intake bumping on the bottom , from my first hand experience of the uhmw liner I have to disagree with you on it outlasting a ss liner and I am willing to provide a ss for the test .

yea we'd have to find someone crazy enough to want to thrash their pump . notice I said I'd supply ss liner and a impeller not the boat

Claude , input shafts have snapped without having to go against a ss stator vane . don't know if there was a run of bad shafts , but there has been more than one in our area break . plenty of customers happy the results of welded stators , if their not they are free to decide what is best for their needs .

it great to hear from everyone on this topic , so Hamilton , why then do they use UHMW skii's on your sled , why not SS and your slide rails should be SS also , and all grain elevators use UHMW in the grain shoots , it is because of the wear factor , we had steel skii's and you put UHMW on them , hahaha , for comparison that a sand blaster and add water and see if you can sand blast a piece of UHMW , good luck , now do the same with steel , the sand will cut it in half , I owned a sandblasting company and i hated it when i had to blast anything that had plastic ,

so u want to take a SS liner against my plastic , ok first set the tolerance at 2-3 thou. and lets see what happens , try it first and see if the motor will even start , without welding the impeller to the housing , u know under cavitation the impeller will expand up to 5-10 thou. ( and that came from Mercury R.D department ) thats why SS is run at such high tolerances compared to plastic , there no heat build up with UHMW , and if so it just wears not seizes ,
UHMW has it's place and it is for bette performance top end and holeshot and mid range , so if u are out there just to pump gravel and wreck stuff stay with your SS ,
i think most people want performance ,

shallow I have already seen how your uhmw wear ring lasts with what would be pretty normal use for the average adventure riverboater . not even talking about the extreme guys , and it's pretty much the same results as has been reported here . why would I set clearance at .003" , I already found that .015 was the minimum 15 yrs ago when I first started making ss sport jet liners . have also found that a tight clearance isn't necessary if your impeller has the right leading edge on it . the hi-skew impeller has shown that hands down the best improvement for the sport -jet because its got so much area on the bite getting flow volume up . sure your uhmw will produce at little more pressure at top rpm with .003 , whats it worth a mph maybe unless it's a 240 in a little step-tec ? and how long does it stay .003" Ok so you made a typo on 1500 rings done, why don't you correct it ?

I don't think we are going to settle the stainless vs Teflon wear ring debate. I will be running a stainless ring this year but I have a stator that looks like the one diggin posted so I was debating on a stainless insert since it's pretty thrashed any way. It seems like a stronger option than the sabre teeth, a lot more money too but more convenient. Any one try different nozzles? 16' lynx not exactly a race boat but a little performance wouldn't hurt.

yes it was around 1500 hrs, combined with testing , i looked back and have made over 400 wear rings out of UHMW, i agree high skew is a great improvement , and when u add that to a uhmw ring it works pretty dam good , i know in the racing world they used them one race and then said it was not fair for the stocker housing, as uhmw was quite abit faster and better hole shot , , thats all i know

I've ran the stock, UHMW, stainless, here is what I found.....
Stock sucks, UHMW is a great improvement for anything except rocks, although I never sent it back in for reshaping with the impeller so I can't comment on whether I tore up the impeller or the wear ring was wore. I should send it back to Shallowman to have it looked at again....
Went stainless and have put many hours on it, sent it in to have the wear ring redone and impeller redone at the same time. Impeller was worn stainless insert was smoothed out, no replacement necessary.
Just for the record I'm running a high skew impeller also.

The UHMW was good on the hole shot and lots of extra push but I found that it wore or my impeller wore to fast for my liking.

That being said I was completely surprised how much of a difference just building up the impeller made after 50 hrs on the boat of what I thought was pretty easy running.....

yep u are very right when using uhmw the impeller will wear out faster then the uhmw , when running stainless on both , we all know that the when two metals of the same material are together they will wear out both equally ( they fight each other ) , so your over all cost goes up as u have to build up both , impeller and wear ring or run over size impeller and that is bad as if u ever need to put a stock impeller in on the river somewhere u will have problems ,
thanks for your input ,
