4-stroke 3 person jet-ski Yamaha WaveRunner
2009 FZS

The FZS 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 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.
