he Powerplant The FX SHO is powered by a 1.8 liter, supercharged, super high output Yamaha Marine Engine. This 1812cc engine, which is purpose built for the marine environment, is the
largest displacement engine ever installed in a personal watercraft. It is also optimized to run on the least expensive Regular Unleaded fuel. Electronic Fuel Injection (EFI): Four
electronically controlled fuel injectors, throttle position sensor (TPS) and intake air pressure and air temperature sensors supply the optimum air/fuel mixture. The results are a smooth, high
power output with low fuel consumption and low exhaust emissions. Specially Designed, One-piece Cylinder and Crankcase Assembly: Provides tremendous engine rigidity that's lighter and stiffer
than two-piece designs. Slant Detection Switch: Electronic switch stops engine and oil pumps immediately if watercraft becomes overturned, protecting motor from unwanted water
ingestion. High Volume Intake Box: With water repellent air filter and flame arrestors. Wet Sump Lubrication: Uses two engine oil pumps to deliver lubricated oil to each moving part
with water-jacketed sump and oil backflow protection. Independent Water-jacketed Exhaust Manifolds with Collector: Achieves high power while keeping noise and exhaust heat under
control.
