Stage 1 Performance Overview
This modification delivers the maximum level of performance through easily installed air intake and pump enhancements. No internal engine modifications are required.
RIVA Performance Power Filter 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.
RIVA Top-Loader Intakte Grate is installed. Unique wing design eliminates prop spin and cavitation while delivering improved handling and top-speed.
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 package using a pitch block to ensure accuracy. Billet impeller cone is included.
RIVA O.P.A.S. Compeition 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: Sea•Doo and RIVA both strongly recommend the use of premium octane (91+) pump fuel in your craft.
NOTE: RIVA Performance Kits intended for competition use only.
