Our intake pump stuffers for the Kawaski 440 / 550  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.
What You Need to Know:
Silicone is not included. We sell our tested High-Quality RTV Silicone. Use of any other type of silicone, adhesive, etc. will void the warranty.
Our silicone requires about 24 hours to cure. Using the product before the cure time will void the warranty.
This product will need to be checked a couple times each season. Failure to inspect the stuffer seal may result in damage to your impeller, pump, or more.
Some aftermarket intake grates (top loaders specifically) will decrease speed or performance.
Note: The slit on these is cut by hand, so each one is a little different. If you’d like a cleaner or more custom look, you can also order it without the slit and cut it exactly how you like.
