RIVA Performance Power Filter Kit 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.
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.
