Description

This modification delivers the maximum level of performance (+3~4mph) through easily installed air intake, exhaust, and pump enhancements. No internal engine modifications are required.


RIVA Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.


RIVA Intake Manifold Upgrade Kit is installed. Precision tapered billet sleeve directly replaces restrictive mesh element in intake manifold enabling engine to produce more horsepower through increased air flow and boost pressure (+1lb).


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


Dramatically reduce cavitation and prop spin with the Worx Racing Pump Seal Kit. Location specific, molded inserts fill the voids in pump inlet shoe that bleed air into pump causing cavitation. Recommended for modified crafts using the Worx Racing FX intake grate.


Worx Racing intake grate improves hook up and handling in rough conditions. Center wing eliminates prop spin and cavitation found with the stock grate along with the SHO's tendency to drop on its nose when the throttle is let off at high speeds.


RIVA/Solas 'R'-Series DynaFly Impeller is a special performance impeller offered exclusively by RIVA and RIVA authorized dealers. Built by Solas, this impeller delivers the ultimate in performance for the FX-SHO. 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.


NOTE: RIVA Performance Kits intended for competition use only.
