Making The Best Even Better.
We’ve redesigned our flagship BF250D model inside and out, adding features, updates and improvements that make these acclaimed V6 outboards better than ever. From easier maintenance to tougher corrosion resistance, the new BF250D outboard take legendary Honda performance into new waters.
Of course, we’ve kept the famous technological advances Honda outboard owners love, many of which are shared with Honda’s renowned automobile engines. BF250D model include VTEC® for explosive mid-range torque. This model feature:
- BLAST™, for maximum holeshot performance.
- Lean Burn Control for remarkable fuel efficiency.
- A best-in class, automotive-style 90 amp alternator and our AMP+® electronic control that automatically increases amperage as needed at idle.
- Multi-Port Programmed Fuel Injection (PGM-FI) consistently delivers the ideal fuel/air mix to the cylinders, for impressive starts, response, performance, and efficiency.
Features
Aerodynamic design, real world benefits
The redesigned BF250D feature the sleek styling of our Progressive V Form design. This new, aerodynamic exterior increases engine cover durability, improves safeguards that help prevent water from entering the engine, and helps protect against paint chipping and scraping.
Simplified maintenance
Common maintenance items have been redesigned or repositioned. Improvements such as a larger diameter dipstick tube, integration of a water separator and fuel strainer, and the relocation of the high-pressure filter (from the high-pressure pump) for easier access reduce maintenance time for routine tasks like oil and filter changes. And easier maintenance means more time on the water.
Tougher corrosion resistance
Components such as the oil pan, thermostat cover, upper mount cover, water pump housing, timing belt tensioner base, water jacket cover, and prop shaft holder now use a higher corrosion-resistant aluminum alloy, resulting in a more durable engine and gear case. Bolts and brackets are treated with a new HI-M coating that delivers improved surface finishing and superior corrosion resistance. The number of anodes on each engine block has been doubled, from two to four, for longer anode life and improved corrosion protection.
3 latch lock & seal cover
The three-latch lock and seal system and two inverted grip points make the cover easy to remove and carry, simplifying maintenance access. The streamlined, simplified undercase includes a heavy protective rubber edge that further protects against the elements, boosting durability.
Dual channel, indirect-air-circuit induction system
The new cowling incorporates a dual channel, indirect-air-circuit induction system that improves airflow, enhancing performance while helping funnel moisture away from the throttle body.
Instant Acceleration: BLAST® System
Boosted Low Speed Torque, or BLAST, improves acceleration at low speeds. A quick movement of the throttle control activates the BLAST® system, advancing the ignition curve aggressively. “Hole Shot” is vastly improved as more horsepower gets the hull up on plane quicker.
Smooth acceleration and power: VTEC® Technology
Honda’s Variable Valve Timing & Lift Electronic Control (VTEC®) system provides power where and when you need it. Available on the BF250D, VTEC gives you a broader, flatter torque curve and smooth power delivery throughout the engine’s operating range. The result is a superior combination of power, torque and fuel economy. VTEC is the modern replacement for displacement.
Lean Burn Control® – Superior fuel efficiency
Lean Burn Control® increases fuel efficiency by allowing combustion to operate on a leaner air/fuel mixture. At cruising speed, this engine runs on up to 19% less fuel* than its predecessor.
*Based on EPA Specific Fuel Consumption Mode.
AMP+ for additional charging at idle
The BF250D offer an industry-first feature, AMP+. At idle, when the engine senses a need for additional amperage, AMP+ automatically increases the rpm’s by 100 to produce an additional 9 amps. AMP+ helps prevent the draining of critical battery power when using multiple accessories, a concern when you’re fishing miles offshore.
High Output Charging – More usable power
The charging system features a 90 amp “On Demand” belt-driven alternator with 60 charging amps. This superior design reduces heat buildup and provides outstanding battery charging across the RPM range.
Quietest in its class
The BF250D is the quietest outboard in their class. Meaning you get to enjoy more of the great outdoors, and less engine noise.
Extreme Duty Gearcase – better durability
The BF250D feature an all new high performance gear case designed to withstand the extreme duty cycles of law enforcement and military patrol boats. This combined with a new gear reduction ratio (2.00:1) and large range of propellers (up to 16 inch diameter) provides high levels of all around performance.
Counter Rotation Available
Counter rotating models are available for multiple engine applications. These models improve efficiency, hull maneuverability and decreases driver fatigue.
