Note: All testing performed with 1/3 tank of fuel, trim in
neutral, sea level elevation, air temp 80-degrees F.
This kit delivers the maximum level of performance (+ 6mph)
through easily installed electrical, 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 Uprade 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 Speed Control Override Module is installed. Module
removes the restrictive speed limiter systems allowing top speed to
exceed factory settings (+3~4mph on US models) with no additional
modifications. This is the "gateway part" necessary for all
modifications that utilize stock ECU.
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.
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.
RIVA Performance Ride Plate is installed. Our ride plate
increases top speed and significantly enhances handling characteristics.
