This kit delivers an awesome level of performance (+8mph on U.S. models) through easily installed electronic and air intake components. No internal engine modifications are required.


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 Speed Control Override Module is installed. Module removes the restrictive GPS controlled speed limiter (68mph USA & 72mph International) on Sea-Doo 300 models. This allows your craft to safely exceed and maintain top speeds that will blow away a stock craft. This is the "gateway part" necessary for all modifications that utilize a stock ECU that has not been reflashed. Quick & easy plug-in installation.



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