Riva's Dave Bamdas explains how the kit works.
How to Easily Add 40-hp to Your Yamaha FX SHO, FZR or FZS WaveRunner
The Riva/Athena Pro-Series ECU provides a huge performance advantage to the
Yamaha 1.8L Engine delivering over 40-hp to the stock SHO engine. ECU is
fully programmable with either RIVA supplied mapping or user adjustable
parameters. Most calibrations require use 91+ octane pump fuel. Plugs
directly into factory wiring harness via waterproof connectors.

Our Power Filter feeds your supercharged 'SHO' engine a steady diet of cool
air delivering greatly improved acceleration and rpm. 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 oversized K&N filter element.

Dustin Farthing's 85-mph Yamaha FX SHO WaveRunner
Yamaha rider Dustin Farthing gives FZ WaveRunner a look at his 85-mph
Yamaha FX SHO. Dustin rode this same WaveRunner to a 1-1-1 finish in the
Florida surf; winning Round 1 of the UWP-IJSBA national tour held in Panama
City Beach, FL.
2011 Yamaha FX SHO
Big on both comfort and performance, this WaveRunner was designed for those
with a big sense of adventure - a thrill made all the more exhilarating
thanks to the massive torque of the FX SHO's supercharged 1.8L engine and
the exceedingly lightweight, responsive NanoXcel hull. And with
comfort-enhancing features like Cruise Assist, maintaining that excitement
during longer rides is as simple as pushing a button.
