I'm removing water pump prior to installing new water pump kit. Have done this 3 or 4 times previous. This time impeller won't release from shaft. Instructions say, turn shaft counterclockwise to unlock impeller key. Turning shaft and jamming impeller doesn't release. Infact can't really turn shaft while holding impeller.
Only difference this time is: Prior to operating season, I took gear case to very experienced local dealer for pressure and vacuum test.Invoice indicates no leaks, but water pump was raised to replace lower gasket....Thanks

Just bump the impeller one way , then the other way with screw driver and hammer. It will come loose on the key.
