" I pulled my lower unit on my recently purchased motor to find the impeller is rust locked/frozen to the shaft. Any secrets or suggestions? I'm using penetrating oil and light taps to the shaft and impeller collar; I've tapped it down lightly to maybe break the rust bond; I've braced a screw-driver under the impeller collar in a pry attempt. I'm reluctant to try heat before the impeller is 'cut away', may also try to find a nut-splitter - just grabbing for straws? (I know - straws won't work either???).

The irony to this drama is that I was told the water pump was broken - needed repair - so no water was being pumped out. However, the impeller appears to be almost new, pliable with no signs of damage. I did find the shaft O-ring about halfway down the shaft however - so probably was dragged out of place when last re-assembled.

Thanks, Cray L "
 
Cray .... The cure is to cut

Cray .... The cure is to cut away the rubber impeller on one side to a point whereas you can use a chisel to cut/split the metal portion of the hub. It can then be slipped off the shaft.

" Thanks for the info, Joe. I wasn't sure of how hard the impeller collar was, so I had some apprehension about damaging the main-shaft bearings. I'll do that first thing in the AM.
Take Care,
