This Cruisair/Dometic P3000BXT Seawater Pump came as a spare with a boat I bought in 2008. I put it on a shelf in my garage and forgot about it when I sold the boat. We're downsizing now, so it's gotta go. I've tested it on the bench and it works as it should. 3000gph rating and the motor runs with either 110/220VAC. The pump has an inlet size of 1 1/4" FPT and an outlet size of 1" FPT. They retail new for ~$1500.
