RIVA Power Filter Kit is installed. The 300 Power Filter feeds your supercharged engine a steady diet of cool air delivering greatly improved acceleration and power. Replaces restrictive stock air box with a high-volume, precision-formed intake duct that attaches to the supercharger via a large 4" adapter. Cool air enters the system via an over-sized K&N filter element. Simple installation & quick removal allow easy access for engine maintenance. Includes water-repellent pre-filter and detailed installation instructions.

RIVA Catch Can/Engine Breather Upgrade Kit is installed. Easy to install catch can/oil breather eliminates power-robbing crankcase fumes and oil vapor from your engine's air intake. Increases horsepower by removing the engine's requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing the oil sludge coating that lowers thermal efficiency.

Solas Concord Impeller is installed. This impeller increases low-end thrust and top-end speed while maintaining correct target RPM for the Stage 2 kit. Constructed of high strength stainless steel, Solas Impellers feature a polished hub and exclusive hub-end water seal for reduced cavitation.


Sea-Doo and RIVA both strongly recommend the use of premium octane (91+) pump fuel in your craft.
