Small engine convenience, big engine performance

This highly versatile twin-cylinder four-stroke engine combines power and responsiveness and offers complete peace of mind. Its low consumption also means that it is more respectful of the environment, with polluting emissions reduced to a minimum.

Also enjoy the many additional benefits that only a Yamaha outboard can provide. These include benefits such as computer-controlled ignition, a special decompressor starting system, a water-cooled fuel pump, and a large muffler; benefits normally found only on high-end engines. You have a winning formula, whether it's for your hobbies or for professional or commercial use.
