Redefining best in class.
With a unique blend of automotive and marine engine technologies, Honda’s flagship, award winning BF250 is a showcase of engineering and technical excellence. With new technology like a unique air induction system, AMP+, a variable idle charging system, and a new gear case, you’re looking at a first-class outboard like no other.
The BF250 also offers the option of Honda’s exclusive Intelligent Shift and Throttle, or iST. iST provides all the features boaters are looking for, including:
- Allows for up to 4 engines and 2 control stations
- Effortless control
- Fine tuning of throttle settings at any speed
- Enhanced docking and slow speed control
- User-programmable system defaults
- Simple, easy to understand user interface
Of course, the BF250 also includes tried and true exclusive Honda technology. Like the BLAST system for a vastly improved hole shot, VTEC technology for more power where and when you want it, and Lean Burn Control for optimal fuel economy. These technologies deliver on Honda’s promise of unparalleled performance, power and fuel efficiency.
Combine all this with Honda Marine’s True 5 Non-Declining Warranty, Honda’s legendary quality and reliability, and our award winning dealer network, and you’ve got the right power plant for your boat.
Reliable, efficient 4-stroke design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
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.
Cooler air, more horsepower – Separate Dual Air Circuits
The BF250 has another industry-first; separate dual air circuits. The first is used to cool the engine where air is drawn into the front of the engine and circulated around critical engine components. A top mounted cooling fan draws cooling air over the alternator. The second intake circuit directs cool air from the upper intake vents, separates out moisture, and then inducts it into the throttle body. This system provides for cooler, denser air for better combustion as compared to conventional under-cowl induction systems.
On-board connectivity – NMEA 2000
NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as SONAR or GPS.
Superior fuel efficiency – Lean Burn Control®
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 30% less fuel* than others in its class.
*Based on EPA Specific Fuel Consumption Mode.
Ultra low 3 star CARB emissions – Environmentally concious technology
Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board’s standards.
True 5 Warranty – unmatched peace of mind
Honda’s True 5 Warranty is the best in the business. This transferable, non-declining warranty is the same on the first day as it is on the last.
Smooth acceleration and power: VTEC® Technology
Honda’s Variable Valve Timing & Lift Electronic Control (VTEC®) system provides power where and when you need it. 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
Engine Alert System – Protects your engine
The ECM monitors vital engine functions and prevents engine damage by alerting the operator of:
- Water in Fuel
- Low Oil PSI
- Critical Engine Function
Counter Rotation Available
Improves efficiency, hull maneuverability and decreases driver fatigue.
Spark plug maintenance cover – easy access
Assists in ease-of-maintenance of the spark plug. This window provides access to the spark plugs without removing the entire engine cover.
Oxygen (O2) and Knock Sensors – Optimum Efficency
Oxygen (O2) and knock sensors help determine the correct fuel flow and ignition curve to maximize performance and fuel efficiency.
4-Front Corrosion Protection System – Fights the elements
A patented, “Double Sealed” multi-layered paint process, sacrificial anodes, stainless steel technology, and waterproof connectors enhance corrosion protection.
Positive Lubrication – better durability
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
High Output Charging – More usable power
The BF250’s 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.
Built-In Pitot Tube
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for speedometer installation.
