Sorrry, the most obvious thing is operator error.
I know to lubricate everything inside the pump real good (a lesson learned), and with this pump/impeller blade direction doesn't matter because it works in either direction...but I did check that the blades were orientated correctly. Seacock was always open. Something happened alright, but it's a mystery to me what it was.
