While replacing the impeller on the motor, I noticed the impeller plate was modified. Where the shaft goes through, the plate is "dimpled" downward around the shaft. It looks like it was purposefully done, but I don't know why. I was ready to pound it back flat, but maybe it was done to increase water flow or something. Any ideas???
