FX140 `08 RPM KIT

RIVA Performance Power Filter Kit is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.
RIVA Velocity Stack Kit is installed. Kit replaces restrictive factory stacks delivering improved throttle response and top-speed. Installs easily with provided set-screw’s that lock onto throttle bodies.
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 in to the voids of the OE transom plate and RIVA Top-Loader Intake Grate significantly reducing cavitation.
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.
RIVA Top-Loader Intake Grate & Performance Ride Plate are installed. Our ride plate and intake grate combo increase top speed and significantly enhance handling characteristics. Prop spin and cavitation found with the stock grate is greatly reduced along with the modified FX-SHO’s tendency to drop on its nose when the throttle is let off at high speeds.
RIVA Pro-Series Sponsons are installed. Our sponsons dramatically improve the handling through their superior blade & backing plate design. Sponson depth and forward/aft position is adjustable to accommodate riding style.
NOTE: RIVA Performance Kits intended for competition use only.
