    It’s no secret to those “in the know” that Yamaha left a lot on the table when it came to the final power output of the Super Vortex High Output (SVHO) engine. Per its factory settings, the industry’s largest displacement 4-stroke (1,812cc) cranks out an unofficial 255-horsepower. That number surprises many given the racing success of the SVHO-equipped GP1800R and FX Series WaveRunners, but dems the facts.
