I intended to use this to use as a deck wash down pump, but my plans have changed. This is a heavy duty commercial grade pump, well suited for bait well, wash down or bilge pump duty. I have misplaced two of the three screws for the cover plate, but they are a common size. Has a new impeller, and includes two additional new impellers along with hose barb adapters. This unit sells for over $350 new - see link for more details.
