Note: All testing performed with 1/3 tank of fuel; trim
neutral.
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 DynaFly Impeller is installed. After extensive im
peller testing we found the Solas DynaFly to be the best all around
impeller. Billet impeller nose cone included.
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.
