This adapter converts the proprietary 1-3/8″ threaded connection on Attwood’s MK2 800GPH Tsunami aerator wakeboard ballast pump to a 3/4″ hose barb connection.

This fitting solves the biggest problem with the Attwood 800GPH Tsunami pump; it allows for connection of 3/4″ hose to the inlet thread on the pump, making it much easier to use this high capacity pump in an automated wakeboard ballast system. This elbow will also include the black O ring standard with every purchase to make a water tight connection.
