Alright, made it work. A guy at church works on boats and he showed me where the impeller was.
And Geoff Howell---I show up at the San Vicente parking lot at 9:00 p.m. Sunday night to describe my plight. Geoff says "I just had my impeller replaced and the old one is in the trash at my house." So he and Blake Hughes scare it up, I install and Monday was saved! Pretty cool and definitely will not be forgotten.
