NEW 2009 Yamaha FX HO Waverunner jet ski

The Powerplant The FX HO is powered by a 1.8 liter, 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.
