Yamaha launches its 2012 Waverunner lineup and the FX series gets completely revamped, with improved stability, comfort and versatility in a sharply-styled, decidedly upscale-looking package. The new FX Cruiser SHO, FX SHO, FX Cruiser HO and FX HO arrive right on cue to celebrate their 10th anniversary.

Great size, same efficiency
Under the seat is a 1,812cc four-cylinder engine – the largest displacement in the industry – that produces 180 horsepower at 7,600 rpm in naturally-aspirated trim (HO) or 235 horsepower at 7,500 rpm in supercharged trim (SHO). It's also the only high-performance, four-stroke engine in its class designed to run on regular unleaded gas, which will translate into nice savings at the pump.

Efficient, dependable and particularly thrifty, the FX engine uses a highly-sophisticated, computerized management system that governs ignition timing, fuel injection mapping, engine diagnostics and off throttle steering. The latter activates when the operator releases the throttle lever and attempts to steer. This assists the operator in turning while the watercraft is decelerating.

For cooling, the FX engine benefits from a thermostatic cooling system featuring a pressure control valve that automatically controls water flow through the engine. Reactive anodes protect the engine from harmful galvanic corrosion, as do the many sacrificial zinc components and stainless steel fasteners (nuts, bolts, hardware).

The impeller housing liner also uses stainless steel for extra rust protection. With high durability in mind, the liner maintains accurate clearance tolerances between the impeller and the housing.
