Other reason I've heard for removing impeller is to avoid it taking a 'set' from sitting in the same position all winter. Somewhere, sometime I read that you should do this if leaving the boat for longer than 2 weeks! It's pretty rare that we are not on our boat at least every two weeks even in winter, but if I were setting my boat on the hard for the winter, I probably would remove the impeller.
