RIVA KAWASAKI STX-15F ENDURANCE KIT Z
Riva's Endurance Racing Kit for the Kawasaki STX-15F contains the same components and specifications that Team Kawasaki developed to dominate the international racing circuit. This modification produces excellent acceleration and a top speed of over 70 MPH using VP MS109 race fuel (Jet X).
High compression racing pistons are installed along with performance intake and exhaust camshafts. Fuel delivery, engine timing and rev limit are optimized to match the increased demands of the modified engine via a race programmed Mitsubishi ECU that plugs directly into factory wiring harness. We highly recommend use of our Performance Power Filter (part# RK13085) with this package.
RIVA Free Flow Exhaust Kit is installed to replace the restrictive sound suppression system located between waterbox and hull exit reducing backpressure and engine operating temperatures. Utilizes stock exhaust outlet and includes RIVA Billet Exhaust Tip.
R&D Aquavein Intake Grate and Ride Plate are installed. Top loader intake grate improves hook-up while reducing cavitation. Ride Plate design allows craft to plane faster increasing acceleration & top-speed as well as improving handling.
Skat-Trak Magnum Pump with Swirl Impeller is installed. Superior materials and design maximize increased power. Swirl Impeller reduces cavitation while producing improved acceleration and top-end speed. OE pump inlet shoe is modified to accept oversized pump.

Skat-Trak reduction and steering nozzle kit is utilized. Interchangeable venturi rings allow fine-tuning to match modified engine and aftermarket pump. Trim of steering nozzle is fixed, but can be adjusted via a turnbuckle system on pump assembly.
RIVA STX-F Pro-Series Adjustable Sponsons are installed. Sponsons dramatically improve handling with a superior blade design and mounting angle. Sponson depth is adjustable to accommodate any riding style.

RIVA KAWASAKI STX-15F RPM KIT
This modification delivers the maximum level of performance (+5 mph) through easily installed air intake, exhaust, and pump enhancements. No internal engine modifications are required.
RIVA Performance Power Filter is installed providing greatly improved performance by replacing restrictive stock intake system. Includes two smaller K&N filters for engine case breather system along with a water repellant pre-filter cover for primary filter.
RIVA STXF Free Flow Exhaust System is installed replacing restrictive secondary muffler. Engine performance is improved by reducing back pressure and harmful detonation. Formed aluminum exhaust tube is lightweight and powder coated to resist corrosion. Includes billet exhaust tip and high temperature silicone couplers. Waterbox modification is not necessary.
R&D STXF Ride Plate is installed. Ride plate provides quicker planing and increased top speed by trimming nose up for reduced drag. Also improves handling and reduces porposing with superior design.
Solas KG-CD-14/21 Concord Impeller is installed. This impeller is ideally pitched to compliment the RPM Kit delivering increased acceleration and top speed. Billet impeller cone is included.
RIVA Pro-Series Sponsons are installed. Our sponsons dramatically improve the handling of the 15F with superior blade & backing plate design. Sponson depth is adjustable to accommodate riding style.

Note: Stock intake grate was utilized for maximum top speed. R&D STX-F intake grate part # 111-15001 can be used for increased hook up in rough conditions, but top speed may be reduced by as much as 2 mph (+/-) in smooth water.
