The Jabsco Wakeboard Ballast Puppy is designed to pump water into Wakeboard Liquid Ballast Tanks and when reversed will also pump water out of them. It has a flow rate of 540 gallons per hour, so it can fill most ballast tanks in about five minutes. It is equipped with a Run-Dry Protection Device to automatically shut-off the pump and protect the impeller from run-dry damage should the pump be mistakenly left on after the Ballast Tank is empty. The Ballast Puppy also features ignition protetion which allows the use of this pump in the engine compartment unlike its less expensive cousin the Simer Pump. This is the same pump used to fill and drain OEM ballast sytems in Mastercraft Wakeboard Boats, 2009 Supra Wakeboard Boats, 2009 Moomba Wakeboard Boats, Correct Craft Wakeboard boats and Centurion Wakeboard Boats.
