Jabsco Xylem Puppy Pump Impeller(52403):

This green impeller is the latest generation wakeboard ballast impeller from Jabsco, designed specifically for use in all Jabsco 18220 Ballast Puppy pumps. This is the OEM impeller for MasterCraft, Correct Craft (Air Nautique), Supra, Moomba, Yamaha, Centurion, and others.

If you've been having problems with your system draining or filling correctly, or if water is leaking into or out of the tanks or bags while the pumps are turned off, replacing your existing impeller will solve all your problems. The green compound impeller is also a replacement for the now discontinued black and yellow compound impellers, so if you're replacing one of those older impellers, this is the part you want.

Impellers are wear components, so over time the efficiency of the pump will be reduced as the impeller wears down. That means your wakeboard ballast system will take longer to fill and drain than it did when new. Replacing a damaged or worn-out impeller will restore the speed and functionality of your Jabsco Ballast Puppy pump to like new condition.
