Kawasaki 650 SX 650 X2 Jet-Ski Pro Watercraft Pump Stuffer

Brand new Pro Watercraft pump stuffer.

It fits all Kawasaki 650 SX X2 Jet-Ski models.

If you want to have an edge when racing, then here you go.

Pump stuffers are simple to install and gain 2+ mph.

To achieve this gain, the stuffer fills in the air pocket in the pump tunnel created while riding your ski. The air pocket is created by 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.
