Our spa motor is very sick (A.O. Smith Century Two-Speed Spa Motor). I'd like to replace it however, I'm not sure exactly what type, model, size, etc. need. I have spoken to a repair tech but he said it is no longer available and has been of little help (I live in a small town so my options are quite limited). I have included (attached) a photo of the existing details. Is this or something similar available and if so where could I locate such?
