The Powerplant * The FZS is powered by a 1.8 liter, supercharged, superhigh output Yamaha Marine Engine. This 1812cc engine, which ispurpose-built for the marine environment, is the largest
displacementengine ever installed in a personal watercraft. It is also the onlyengine in the high-performance, four-stroke category optimized to runon the least expensive Regular Unleaded fuel. *
Electronic FuelInjection (EFI): Four electronically controlled fuel injectors,throttle position sensor (TPS) and intake air pressure and airtemperature sensors supply the optimum air/fuel mixture.
The resultsare a smooth, high power output with low fuel consumption and lowexhaust emissions. * Specially Designed, One-piece Cylinder andCrankcase Assembly: Provides tremendous engine rigidity
that's lighterand stiffer than two-piece designs.
