The RIVA Speed Control Override Service removes the restrictive GPS speed control function on Sea-Doo 325 models delivering significant increases in top speed. Also allows system to start in "Sport Mode" for maximum performance. "Touring Mode" can be manually selected after start-up. This is a "mail-in" service requiring you ship your original ECU, RF D.E.S.S Lanyard and RF D.E.S.S. Post (3 items) to RIVA for programming.

Upgraded Tuning Parameters:

Removes GPS controlled speed limiter.

Increases top speed utilizing stock ECU without tuning or modifications.

Works on all 2024 & newer 325hp Sea-Doo models.

Can deliver 80+mph top speed on 325hp RXP-X & RXT-X models.

Allows system to start in "Sport Mode".

Does not affect ECU tuning or exhaust emissions.

For optimal performance we highly recommend upgrading your pump impeller to a Solas SXX-CD-14/19 Concord Impeller. This impeller reduces cavitation and significantly improves acceleration enabling your craft to reach top speed quicker than the stock pump impeller.

NOTE: Stock ECU limits performance for first 10 hours of operation. Top speed increases should be measured after 10 hour break-in period.

Top speed without override service:

North American Models: 68 MPH
International Models: 72 MPH
