Product Description


This kit delivers a significant level of performance (+10mph on U.S. models) through easy to install, bolt-on engine, exhaust, and pump enhancements. Requires use of fresh premium octane pump fuel (91~93).
RIVA Power Filter Kit is installed. Power Filter Kit draws cold air from outside your engine compartment delivering awesome performance and eliminating power-robbing heat intake. Air intake is separated from hot engine compartment with rigid thermal bulkhead that installs between engine & fuel tank. Cold air is delivered to engine via large 4” smooth-bore ducting that is attached to supercharger with unique velocity stack and sturdy billet clamps.
RIVA Sea Doo XX-2 Charger. Our new XX2-Charger delivers 15 psi of boost pressure at 8,500rpm producing arm wrenching acceleration and increased top speed. High performance billet impeller & 4MM spacer increase horsepower through superior impeller blade design and larger interior housing volume. Lightweight billet impeller features a sophisticated blade design that is precision balanced to deliver smooth operation. Spacer & impeller install quickly and easily onto stock supercharger base plate.IJSBA Limited Class legal. Requires RIVA/Athena Pro-Series ECU, RIVA Pro-Series Fuel Injectors (100lb) & RIVA Fuel Pressure Regulator Kit for correct calibration. Includes detailed installation instructions.
RIVA Intake Manifold Upgrade Kit is installed. Removal of restrictive screen element from inside of intake manifold enables your engine to produce more horsepower through increased boost pressures (+1lb). Special o-ringed, billet block-off plug with integrated fitting for aftermarket boost pressure gauge fills opening left after removal of screen element.

Easy to install catch can/oil breather eliminates power-robbing crankcase fumes and oil vapor from your engine’s air intake. Increases horsepower by removing the engine’s requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing the oil sludge coating that lowers thermal efficiency. Excess oil vapor is routed to our translucent catch can where it condenses and collects for occasional draining via integrated petcock valve. Kit includes K&N breather and Sea-Doo mounting bracket along with all necessary hardware & installation instructions.
RIVA Fuel Pressure Regulator Kit is installed. Kit provides precision control of fuel pressure to meet fuel requirements of modified engine. RIVA Stage 3 Kit requires a consistent fuel pressure of 58psi (static/non-rising rate). OEM fuel pressure varies between 48~58psi. Plugs directly into original fuel system with OEM connectors and features a large 3/8″ fuel return line. Includes integrated liquid-filled pressure gauge and billet Fuel Pressure Regulator Block-Off necessary for removal of stock fuel pressure regulator in fuel tank.
Bosch VT1100 Fuel Injector Kit is installed. High performance 1100cc fuel injector kit supplies modified Sea-Doo engines with the necessary amount of fuel to produce reliable horsepower.
RIVA Valve Train Upgrade Kit is installed. Titanium valve retainers and heavy-duty valve springs increase reliability of modified engine by recucing the possibility of valve float at high RPM. To ease installation of Valve Train Upgrade Kit we offer a unique Valve Compression Tool that allows installation without removal of cylinder head saving you time and money.
RIVA Free Flow Exhaust Kit is installed. Kit allows removal of restrictive sound suppression system located between waterbox and hull exit. Improves engine performance by reducing back pressure & restriction.
RIVA MaptunerX BRP Bundle is utilized to reflash original ECU. MaptunerX provides ability to quickly and easily load performance tunes directly into your stock ECU eliminating downtime that results from shipping for programming. Performance Tunes are calibrated to provide optimum fuel delivery, ignition timing and rev limit to compliment RIVA Racing Performance Kits. OEM dash display, engine diagnostics & engine safety functions are retained. MaptunerX features a full color, touch screen display, ability to restore stock tune settings and access to RIVA’s complete tuning library and technical support.
RIVA Thermostat Kit is installed. Kit reduces operating temperature of modified 4-TEC® engine by 30°F for maximum reliability and performance.
Solas ‘R’-Series Concord Impeller is a special performance impeller offered exclusively by RIVA and RIVA authorized dealers. This impeller is specifically pitched to our specifications using a pitch block to ensure accuracy. Billet impeller cone is included.
83.5mm Reduction Nozzle is installed replacing the standard 87mm reduction nozzle. Smaller exit nozzle compliments the 15/19R pump impeller maximizing performance.
