2009 FX SHO Yamaha Waverunner Jet Ski

The 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. * 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. The Jet Pump Propulsion System * The FX SHOs 155mm hyper-flow jet pump propulsion system with three-blade stainless steel impeller is designed to maximize water flow for high performance. The FX SHO pump configuration provides excellent hook-up and smooth acceleration. * The industrys only Reverse with Traction Control technology: Maintains the perfect RPM to provide the optimal speed for effectively maneuvering when the watercraft is in reverse. * Quick Shift Trim System (Q.S.T.S.): Mechanically operated, this system offers instant change in the attitude of the watercraft while underway allowing for tighter turns or quicker acceleration on plane, as the rider prefers. Q.S.T.S. offers 24 degrees of total trim range. * Stainless Steel Impeller Housing Liner: For high durability, the liner maintains accurate clearance tolerances between the impeller and the housing. * High Flow Intake Duct and Grate: The dynamic shape of these items directs water flow into the pump for better thrust, performance and hook up. * Pumps are Manufactured with YDC30: A combination of zinc and copper alloys, developed by Yamaha marine engineers, that offers excellent corrosion protection.
