Meh...I just put the pump back in and inspected the shoe and grate. The stator really doesn't look any worse than it did last year, so I doubt I am getting major cav there.
The grate has some dings, but no damage incurred from that log that I can see.
The pump shoe has a piece missing between grate and plate, on one side, about 1 inch wide. Not much worse than it was before, but a little bit.
I caulked it up with black silicone. Plus, I sealed the midshaft carrier - which wasn't sealed at all before.
I'll put it back in the water tomorrow and see how she does.
