Yamato racing was established in 1951 under the former name of the Kokusai Kyouti Kougyo Co.

As the motor boat racing law was introduced they developed the first Japanese made racing motor roughly based on a Mercury design and have been producing motor boats and race engines mainly for the pari-mutuel motor boat racing series ever since.

In Japan Yamato racing is a professional sport where top drivers can earn impressive amounts of prize money and attract hugh crowds. The world including Europe were quick to adopt this awesome class were numbers soon blossomed to see Yamato Hydroplanes embedded as the grass routes of inshore racing and now the largest class in the world. Unlike all other classes of race boat the Yamato series is unique as it sees the pilot laying face down with a hand trigger as the throttle. Powered by a 400cc 33HP fixed drive engine it is capable of achieving a top speed of 70MPH and takes corners by planing across the the surface of the water, just think of rallying on water and you have the basic principle.

Now everyone can experience the awesome sensation of laying face down inches from the water in a Yamato OSY400 Hydroplane Powerboat.
