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. * Slant Detection Switch:Electronic switch stops engine and oil pumps immediately if watercraftbecomes overturned, protecting motor from unwanted water ingestion. *High Volume Intake Box: With water repellent air filter and flamearrestors. * Wet Sump Lubrication: Uses two engine oil pumps to deliverlubricated oil to each moving part with water-jacketed sump and oilbackflow protection. * Independent Water-jacketed Exhaust Manifoldswith Collector: Achieves high power while keeping noise and exhaustheat under control.
