PROWATERCRAFT PUMP STUFFER FOR KAWASAKI 440/550
Our Intake Pump Stuffers are simple to install and gain 2+ MPH affordably.
To achieve this gain, our stuffer fills in the air pocket in the pump tunnel created while riding your ski.
The air pocket is created with the concave surface of the pump tunnel while water is rushing over. This action drags water and creates cavitation making you lose power and drive. When you install this pump stuffer, you will see more drive and feel more ‘sucked down’ to the water.
