JABSCO BALLAST PUPPY PUMP SELF-PRIMING .5" NPT 9 GPM W/REVERSING SWITCH. The 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 9 gallons per minute, so it can fill most ballast tanks in about five minutes. It is equipped with a Run-Dry Protection Device (patent pending) 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.
Adds approx 80lbs (36kgs) of ballast per minute
Reversible to both fill and empty tanks
Simple design means fewer wearing parts.
