This modification delivers the maximum level of performance
(+ 4mph) through easily installed air intake, exhaust, and pump
enhancements. No internal engine modifications are required.
RIVA Performance Power Filter is installed providing
greatly improved performance by replacing restrictive stock intake
system. Delivers an increased volume of air via a large 4" diameter
intake duct and oversized K&N filter element. Includes water
repellant pre-filter cover for primary filter.
RIVA Pro-Series Water Box and Free Flow Exhaust Kit are
installed. Provides a larger unrestricted exhaust outlet for improved
acceleration and top speed. Includes new billet thru-hull outlet and
high-temperature silicone couplers.
Top-Loader Intake Grate is installed. Eliminates prop spin
and cavitation while delivering improved handling and acceleration with
no loss in top speed.
RIVA Performance Ride Plate is installed. Ride plate
provides quicker planing and increased top speed by trimming nose up
for reduced drag. Also improves handling and reduces porposing with
superior design.
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.
After extensive testing of aftermarket impellers we have
determined that the stock impeller provides the maximum performance for
both stock & Stage I applications. We will report updates to
our impeller recommendation at such time as we find an aftermarket
advantage to the stock impeller.
