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. 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 are installed. Kit replaces restrictive sound suppression system located between water box 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 pump inlet shoe significantly reducing cavitation.

 

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 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.
