I think you should pick up the Eastwoods cylinder head porting kit and clean up all those gnarly dings in the stator...

They work really well on the aluminum parts and you just toss em when you're done.

Do you have a puller? I would pull the impeller and just give it a real close inspection. The entering side is where the water enters the impeller and the leading edges are very delicate.

yeah I've got boxes of cartridge rolls I use to do a lot of cylinder head work,  the leading edge most definitely needs to be cleaned up the rocks ate the edge up pretty good,  I was most worried about the vibration so I hope that's gone.
