RIVA Performance Power Filter is installed. Screen-type element mounts directly onto opening at front of original flame arrestor case replacing the restrictive baffling system. Provides improved throttle response and all around performance gains.


RIVA Free Flow Exhaust Kit is installed. Kit replaces restrictive sound suppression system located between waterbox and hull exit reducing backpressure and engine operating temperatures.


RIVA Pump Seal Kit is installed. Location specific molded inserts are siliconed into the voids of the OE pump inlet shoe significantly reducing cavitation.


Worx Intake Grate & RIVA Performance Ride Plate are installed. Ride plate and intake grate combo increase top speed, significantly enhance handling characteristics and create better “hook up” in choppy water conditions. Prop spin and cavitation found with the stock grate is greatly reduced.


RIVA/Solas Concord 'Set-Back' Impeller is a special performance impeller offered exclusively by RIVA and RIVA authorized dealers. Built by Solas, this impeller delivers the ultimate in performance. Inner hub is machined allowing impeller to mount closer to vein housing for reduced cavitation and more top speed. Impeller blades are digitally calibrated to RIVA's uniform pitch specifications. Impellers are then dynamically spin-balanced at high RPM. A precision factory blueprinting process is performed far exceeding any "prop shop" services available. Includes Billet Impeller Cone for maximum performance and durability.


Original 87mm Yamaha GP1200R Exit Nozzle is installed replacing the standard 85mm GP1300R exit nozzle. Larger exit nozzle compliments the 13/20 'Set-Back' impeller maximizing performance.
