2009 YAMAHA FX SHO, The FX SHO is powered by an all new 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 the only engine in the high-performance, four-stroke category 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. Yamaha Engine Management System (Y.E.M.S.): An integrated, computerized management system that controls and adjusts such functions as ignition timing, fuel injection mapping, engine diagnostics and off throttle steering. The OTS function of Y.E.M.S. activates when the operator releases the throttle lever and attempts to steer the watercraft. This assists the operator in turning while the watercraft is decelerating. Independent Water-jacketed Exhaust Manifolds with Collector: Achieves high power while keeping noise and exhaust heat under control. Thermostatic Cooling System: Water flow through the engine is automatically controlled through a thermostat sensor. Corrosion Protection System: Sacrificial zinc anodes protect the engine from harmful galvanic corrosion. Stainless steel fasteners (nuts, bolts, hardware) provide a long service life. Cylinders, cases and heads are all treated with a durable oxide coating to form a barrier between corrosion and expensive engine parts. Electronically Controlled, Variable Ignition Timing: For exact ignition advance control at all throttle positions and RPMs. Direct Ignition: For more efficient combustion.
