Sea-Doo RXT-X 255 Stage 1 Kit (2008 - 2009)


excl. tax plus shipping


This modification delivers the maximum level of performance (+6mph) through easily installed air intake and pump enhancements. No internal engine modifications are required.

  • RIVA Performance Power Filter Kit is installed. Power Filter provides greatly improved acceleration and a 150~200rpm increase by replacing restrictive stock intake system. Features a large 3" diameter intake duct and oversized K&N filter element that feeds your Supercharger with a steady diet of cool air. Installs quickly and securely using a silicone coupler and sturdy bracket.
  • R&D Aquavein Intake Grate is installed. This intake grate greatly reduces prop spin and cavitation while delivering enhanced acceleration and 2mph additional top-speed. Deep side rails and R&D's patented Aquavein technology improve straight-line stability and handling.
  • Solas 'R'-Series Concord Impeller is a special performance impeller offered exclusively by RIVA and RIVA authorized dealers. This impeller is specifically pitched for our Stage 1 RXT-X package using a pitch block to ensure accuracy. Billet impeller cone is included.
  • RIVA 2° Pump Wedge is installed. 2° wedge trims up your pump nozzle raising the bow of your craft for less drag substantially improving top-speed. Features a double-sided lip to retain silicone sealant and prevent cavitation.
  • RIVA VTS Extension Rod is installed. Allows maximum "nozzle down" adjustment after installation of RIVA Pump Wedge. Necessary with Stage I modification to trim bow down off the line while providing maximum top speed advantage when trimmed up.
  • RIVA Pro-Series Reduction Nozzle is installed. Replaces original 87mm reduction nozzle allowing nozzle exit diameter to be easily changed via interchangeable ring system. Includes three stainless steel rings in graduated sizes (81, 82 & 83mm) to compliment the impeller pitch in varying conditions maximizing top speed and performance.
  • RIVA O.P.A.S. Competition Kit is installed. Kit provides more predictable handling characteristics while still retaining the off-throttle steering benefits of the O.P.A.S. by preventing the fins from dropping when pump is out of the water in choppy conditions.

NOTE:Use of premium octane pump fuel (91+) is required. RIVA Performance Kits intended for competition use only.
