As we mentioned a few weeks back, the Personal Watercraft market is currently in the grips of a horsepower war which was started last year when Kawasaki introduced a turbocharged, 1500cc, 250 horsepower PWC that’ll run 68 mph (60 knots) on water. Not surprisingly, all the other manufacturers have responded in kind, with Yamaha creating an all-new purpose-built craft of astounding technological prowess. The power plant for the new top-of-the-range SHO (Super High Output) WaveRunner models is a compact 1812cc, fuel-injected, supercharged, intercooled, four-cylinder engine. Perhaps even more importantly, the entire hull uses Nanotechnology to achieve a hull 25% lighter than the previous model, yet even stronger. Check out how the new SHO compares here.
