I just put an AA stainless impeller into my boat. The pump is a dominator. I set the clearance from the trailing edge of the wear ring and the leading edge of the impeller to .025. I noticed when I ran the boat today, that there was some noise coming from the pump.
What should the wear ring clearance be between the wear ring surface and the impeller? I cant see any visible signs of rubbing anywhere, and the impeller spins free by hand.
I cut the impeller down from a 9.25 to an AA. Could it be possible that I have to balance this again?
Thanks for the help, Ryan
