Sr Gibson, look at the leading edges of your impeller blades... it's been chewing on something there can be no doubt about it! Something was without a doubt sucked into that jetpump and went thru the pump, the leading edges of the impeller are all beat up the rubber nosecone is even torn up. I don't know what it was or when it was in there, but it was in there and made a mess of things. This is not a factory defect issue, it doesn't fall within the warranty. I don't think it was a rock or even a bunch of rocks they wouldn't have torn the rubber nosecone up like that, it almost had to be wood a branch got in there and was wrapped around the shaft briefly (tearing the rubber nose cone up) then shredded and spit out the back IMO. That impeller looks like it's seen a hundred or more hours of service, not 8!
If the machine was never sold to anybody else and returned before hour 1 on the hourmeter, and the dealership does not test drive the units they get in for sale this seems obvious to me, then there's not much else one can say except you unfortunately sucked something into and thru that pump. Eeeek!
The wear ring didn't damage the impeller blades and rubber nosecone, something foreign did all that damage and it was probably partly wrapped around the shaft for a brief time due to the nosecone damage.
You were the only 1 to drive it I guess? Did ANYBODY else take it for a spin at ANY time during the 8 hours you had it running? Anybody at all? This aught to have made some racket for sure!
The dealership and BRP are sooooo not going to warranty that. I can't see any way to blame them having seen the pics of the inside of that jet pump. Sorry. :-(
