yamaha intros fourstroke v6 outboards

Yamaha Marine recently introduced the world's first and only V6 four-stroke outboards in 225 and 200 hp models. These new models are clean running, quieter and more fuel-efficient than traditional two-stroke outboards.

These revolutionary motors are receiving rave reviews in the boating press. Consumer acceptance of the new technology has been equally enthusiastic.
Yamaha designed the F225 and F200 from scratch to be marine engines. Sleek and compact, the F225 is about the same size as a two-stroke outboard of the same class. Yamaha's design has made size and weight differences between two- and four-stroke V6s a non-issue. The company also offers four-stroke outboards in 15 horsepower classes, delivering its first four-stroke model, a 9,9, in 1985.

Yamaha's F225 or F200 four-stroke outboards eliminate the need for two-stroke oil to be mixed with fuel. As a result, the new V6 four-strokes exceed the Federal EPA emission standards for the year 2006. They also comply with the more stringent California Air Resources Board (CARB) requirements which are already in effect.
