This is great deal on a BRAND NEW Pro Watercraft Pump Stuffer
It fits all 440-550 Stand up Jet-Ski Models
If want to have an edge when racing, then here you go
Pump Stuffers are simple to install and gain 2+mph
To acheive this gain, the stuffer fills in the air pocket in the pump tunnel created while riding your ski. The air pocket is created with a 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.
