Kawasaki 440/550 hull extensions come out an extra 5/8″ to grab the water for longer for a reduction in porpoising and increases the rear grip. These improve the overall handling of the ski. These are a direct replacement of the badly-designed OEM caps that fill with water and sand.

Sold with pre-molded rear exhaust hole for those with this outlet configuration.

  • This product fits: Kawasaki 440 / 550 (all years)

    Less porpoising, easier to get the bow to settle down when going over boat wakes, looks cool. Super easy install.
    Thanks guys!
