Yamaha’s 1.8 liter, Supercharged, Super High Output engine is the largest ever in a PWC and 300cc’s larger than any other model. Compact and lightweight, it’s also 45 pounds lighter and packed with power to provide the best acceleration and top speed ever offered in a WaveRunner. Earning a 3-star low-emission rating, it is also the only engine in its category optimized to run on the least expensive regular unleaded fuel.
