Rock through impeller
Long story short...Had a rock go through my impeller and lodge in exhaust vains(happened at low rpm..just off idle) not much "damage" to rock..LOL ..was able to pry it out and then fish it out with a coat hanger. Checked the intake side...small "ding" on one of the impeller blades (wear rings seams OK..original) NOTE ..going to replace ring in off season(original). Noticed I am a bit down on top end..and am bouncing a bit off limiter out of the hole..(7,600 rpm) Very slight vibration at top end.. Question.....possible bend blade on impeller?? Better to replace..or have impeller repaired (and impeller blades reset?) Cheers

That does sound impeller related.
Either replace it or have it reworked.
Change the wear ring at the same time.

Repair it for $80-100. Done like new
edit: OEM plastic rings are garbage. Collect holes and gouges too easily. Go stainless. I just bought the Solas SS from Impros for $100. Very nice piece....just as nice as the $200 SS Riva. So for $200 your impeller is like new and you'll have SS ring. Not bad

Damn you got lucky. I had a rock get sucked up and caused this.

The pros: lasts forever and never gets holes and chunks taken out of it. Worst you'll see is some scratching. My first one has been great for about 260-280hrs. Keeps its tight clearance even after some damage. If you don't want damage to the impeller, the key isn't to buy OEM wear rings....instead, the key is to just not suck shit up. But at least with SS, you'll only have to repair your impeller, not repair your impeller PLUS replace the wear ring.
Cons: can't think of any
OEM ring: always loosing chunks and/or accumulates deep scars - loosing that tight clearance.

Wear Ring...... Been thinking of stainless....But....as have heard and being an Ex Boat owner... Aluminum prop....hit rock.... prop gets dusted...... Stainless Prop... it don't bend....soooo the rest of the lower end drive train takes a s**t kicking!
So with the OEM plastic ring.....it takes it .......not the rest of the inards.
Just my logic about it....

I ride in the desert. I've sucked rocks twice in 300hrs (with and without a SS ring). To this day, I just don't see enough risk/reason to NOT buy SS rings

Ride in the desert......Hmmmmm... that sand must be tough on the pump!! LOL (jk)
Thanks for the info..... Me thinks I will lean towards the SS ring..
