For the record -- and for all the other people who may read this thread in the future -- I'm very doubtful that the pump actually DID run for years wired 240V, but supplied 120V. As far as I know, with most pool motors, this is not possible.

I'd guess that somewhere in the assembly and repair process, some wiring got switched around.
