Honda BF250 Features and Specifications

The Honda BF250 four-stroke engine is the newest and most powerful outboard to join the Honda Marine lineup – and now the company’s flagship model. The design of the BF250 incorporates a number of advanced technological innovations that contribute to the engine’s high fuel economy and superior performance. The 3.6 liter VTEC® (Variable Valve Timing and Lift Electronic Control®) engine is equipped with an all-new gear case, incorporates the world’s first marine direct air induction system of its type on a production outboard (providing for cooler, denser air for better combustion than conventional under-cowl induction systems), and has a full-throttle RPM range of 5300-6300.

The Honda BF250 engine also incorporates the Boosted Low Speed Torque (BLAST™) System through which holeshot and acceleration are dramatically improved by advancing ignition spark timing to within one degree of the knock limit during ‘hammer down’ acceleration.
