I just updated the wiki but figured I add my recent experience here.
I noticed yesterday there was no water pumping out of the exhaust. Quick check of the impeller and it looked fine. I cleaned the strainer, pulled the hoses and all seemed clear yet it still wouldn't pump. I popped in an old globe blue impeller and all was well. Did I miss something? Slightly worn profile w/ cover plate groves the cause? Seems like I would still be getting some water as I primed the lines, etc.
Doing some head scratching at home today with what looked like a perfectly good impeller I noticed the metal portion that is keyed to the shaft was more or less free spinning inside the rubber impeller itself. Poor design I would say as it looks like more of a friction fit between the metal and the rubber.
Anyway... a simple heads up when doing an impeller check as I'm sure I'm not the first or the last w/ this issue.
