RIVA Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.
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.
Worx Intake Grate is installed. Prop spin and cavitation found with the stock grate is greatly reduced along with the modified FX's tendency to drop on its nose when the throttle is let off at high speeds.
Solas Concord 'Set-Back' Impeller is a special series of performance impellers offered exclusively by RIVA and RIVA authorized dealers. Built by Solas, these impellers deliver the ultimate in performance. Inner hub is machined allowing impellers to mount closer to vein housing for reduced cavitation and more top speed. All three 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 RIVA Billet Impeller Cone for maximum performance and durability.
NOTE: RIVA Performance Kits intended for competition use only.
These are additional performance upgrade parts that can be purchased individually to improve the performance kit.
