Whether for use in a new ballast system, or to replace a failed factory pump, the Attwood Tsunami 800 is a fantastic choice.

The Attwood Tsunami 800GPH centrifugal aerator ballast pump is a dependable, long-lasting, compact and inexpensive aerator style wakeboard ballast pump. The low price, reliable reputation, and speedy 800GPH speed rating make this wakeboard ballast pump one of our best sellers. And thanks to the replaceable cartridge motor design, if the pump does fail, simply install a new cartridge, and you essentially have a brand new pump. Compared to expensive reversible pumps that need to be completely replaced if they fail, the Attwood Tsunami 800 is a great value.

For flexibility, we allow you to choose from the following discharge fittings based on the best option for your application. Please note that no discharge connection is included with the pump, so you will need one of the below adapters.

This pump is a direct replacement for the ballast pumps used on all Malibu wakeboard boats, and the drain pumps used on Centurion, Supra and Moomba wakeboard boats during the mid-2000s. For durability, the housing is made of rugged fiberglass and mineral-filled polymer that will easily withstand a pounding in rough water and is resistant to chemicals and petroleum.

With 3/4" NPSM inlet and 1-3/8" UNF outlet threads, this pump can be adapted to fit most applications with the various fittings we offer, but will most commonly be used in a system that utilizes 3/4" hose and connections.
