Innovative four stroke engine is Honda’s most powerful and now its flagship entry in the crowded outboard propulsion markets. The new BF250 horsepower (hp) four-stroke engine, the most powerful outboard ever to join the Honda Marine lineup, is also the company’s flagship model. Incorporating a number of advanced technological innovations that contribute to the engine’s high fuel economy and superior performance, the 3.6-liter engine is additionally equipped with an all-new gear case, the world’s first marine direct air dual circuit induction system of its type (providing for cooler, denser air for better combustion than conventional under-cowl induction systems) and has a full-throttle rpm range of 5,300-6,300.
