The Honda BF250 engine incorporates the world’s first marine direct air dual circuit induction system of its type on a production outboard. The first circuit draws air into the front and around critical engine components, and a top-mounted cooling fan draws cooling air over the alternator. The second circuit routes cool air from the upper intake vents, removes moisture, and then inducts it into the throttle body. This system provides for cooler, denser air for better combustion than conventional under-cowl induction systems.

How the overall design and styling concept of the BF250 engine gives enhanced performance:

Honda BF250 Launch Napoli Oct 2011The styling concept of the Honda BF250 is a departure from other Honda Marine outboards in that the aesthetic design is sleeker and slimmer. In addition, the cowling of the new BF250 exhibits a sharper, more angular profile over previously introduced models. The overall design is streamlined and more aerodynamic, with chrome lines conveying power and speed.

Other design attributes that enhance the operation and performance of the Honda BF250 engine:
The Honda BF250 engine is NMEA 2000® certified. NMEA 2000 is a combined electrical and data specification for a marine data network for communication between marine electronic devices such as depth finders, nautical chart plotters, navigation instruments, engines, tank level sensors and GPS receivers. Parameters of this certification are defined and controlled by the U.S.-based National Marine Electronics Association (NMEA). This accreditation signifies that a product has been tested to meet specific critical safety criteria and to correctly implement network management and messaging. In meeting this certification, the Honda BF250 does not require the added expense of proprietary gateway devices; the certification also correlates with enhanced safety as the new BF250 engine is equipped with engine oil pressure and overheat information alerts.
MARINE-BF250-3 copyThe design of the Honda BF250 incorporates a spark plug maintenance cover which assists in ease-of-maintenance of the spark plug. This window provides access to the spark plugs without removing the entire engine cover. The engine also includes a high-quality, cost-effective nickel spark plug that seals the combustion chamber.

The technologically advanced Electronic Control Unit (ECU) in the Honda BF250 can predict the operator’s shifting operation based on changes in engine speed and throttle position. In order to reduce the shifting load, the ECU actually controls the ignition timing to modify torque when the operator shifts from partial to neutral.
