looks like mine

 

I contacted vortech and sent them the pics. The guy I was talking with stated he's never seen one that pitted before. It would cost roughly $500 for complete service including impellar replacement. If a lot of their impellars are like that . . . I don't know. I thought these guys were suposed to be good. I sent a reply to his initial respons, so I'll patiently await his reply.

 

Did it come from the factory like that, or did it get that way over time?
