This kit delivers a maximum level of performance (+5mph)
through easy to install, electronic, 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.
RIVA Stage 1 Engine Cooling Upgrade Kit is installed. Kit
improves water flow to Yamaha SVHO engine and intercooler for improved
performance & reliability. Greatly reduces loss of power due to
"heat fade" on stock and Stage 1 modified craft.
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.
RIVA Top-Loader Intakte Grate is installed. Prop spin and
cavitation found with the stock grate is greatly reduced along with the
modified FX's tendency to drop on its nose when the throttle is let off
at high speeds.
Solas Concord Impeller is installed. New design
incorporates a large blade area and superior hub design that deliver
increased acceleration and top speed. Billet nose cone included.
