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 Power Filter Kit is installed. The 300 Power Filter feeds your supercharged engine a steady diet of cool air delivering greatly improved acceleration and power. Replaces restrictive stock air box with a high-volume, precision-formed intake duct that attaches to the supercharger via a large 4" adapter. Cool air enters the system via an over-sized K&N filter element. Simple installation & quick removal allow easy access for engine maintenance. Includes water-repellent pre-filter and detailed installation instructions.

RIVA Catch Can/Engine Breather Upgrade Kit is installed. 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.

RIVA 300 XX Charger is installed. High performance billet impeller & 3MM spacer increase horsepower through superior impeller blade design and larger interior housing volume. Spacer & impeller install quickly and easily onto stock supercharger base plate delivering 17.5 psi of boost pressure.

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.

RIVA Stock Retainer Upgrade Kit is installed. Titanium valve retainers increase reliability of modified engine by reducing 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 water box and hull exit. Improves engine performance by reducing back pressure & restriction.

Solas Concord Impeller is installed. This impeller increases low-end thrust and top-end speed while maintaining correct target RPM for the Stage 3 kit. Constructed of high strength stainless steel, Solas Impellers feature a polished hub and exclusive hub-end water seal for reduced cavitation.

* = iDF Models: Average top speed reduced by 2mph due to mechanical drag on driveline. We do not recommend exceeding Stage 2 due to limitations of iDF internal components.

NOTES:

Siphon Break Delete Kit required with Exhaust Modification on 2023 models.

Sea-Doo and RIVA both strongly recommend the use of premium octane (91+) pump fuel in your craft.

FOR COMPETITION USE ONLY. KIT NOT FOR USE ON POLLUTION CONTROLLED VEHICLES.
