I wonder how hot it must have got...

I had the same problem with 1 of my Sedra 9000. The impeller has what seems to be a rubber membrane over the magnet and if it develops a leak the salt water gets into the iron of the magnet and it rusts immediately. As it rusts it expands ever so slightly and then seizes within the impeller housing. I ruined the impeller trying to get it out of the housing but once out the housing seemed OK. I then bought a new impeller from OA ($50 - $60) and everything was fine.
