Honda Marine Outboard | BF250 | Large-Size | 4-stroke
Honda Marine has redesigned the Honda BF 250 HP 4-stroke outboard making significant improvements inside and out. Also making maintenance easier and tougher corrosion resistance taking this already great motor to the next level.
Aerodynamic design, real world benefits
The redesigned BF200, 225, and 250 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.
Superb control and easy installation: iST Intelligent Shift and Throttle
Honda's exclusive Intelligent Shift and Throttle (iST) command and control system delivers superb control plus plug-and-play installation of Honda Marine products and third-party controls and devices, such as the Optimus 360 Joystick. iST offers multi-engine applications, with fine tuning of throttle settings at any speed, enhanced docking and slow speed control, and a simple, easy to understand user interface. nly. Available on select BF200, 225, and 250 models.Learn More
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.
Boaters who prefer traditional controls will take a purist’s pleasure in Honda’s smooth operating mechanical command and control system. Its reliable design delivers the responsiveness and feel traditionalists love. Our mechanical control supports up to two engines and a single-helm location as well as a side-mount configuration.
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.Learn More
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 BF225 and BF250, 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.Learn More
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 20% less fuel* than others in its class.
*Based on EPA Specific Fuel Consumption Mode.
AMP+ for additional charging at idle
The BF200, 225, and 250 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.Learn More
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.
Defy the Elements with 4-Front Corrosion Protection System
A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.Learn More
White models available
The BF250 offers a choice of white and silver models to complement your boat.
World Famous Quality
The BF200, 225, and 250 share many components with the Honda Ridgeline, Odyssey, Honda Pilot, Accord, and Acura RL, gaining years of proven Honda engineering, precision manufacturing and reliability.
Large Displacement V6 - Top performance and durability
A powerful, compact 24 valve SOHC design, without the bulk and weight of long intake runners and multi-camshafts. The narrow V6 design offers top performance and durability as well as great fuel economy.
Quietest in its class
The BF200, 225, and 250 are the quietest outboards in their class. Meaning you get to enjoy more of the great outdoors, and less engine noise.
Multi-port Programmed Fuel Injection (PGM-FI) - Powerful performance
Programmed Fuel Injection delivers the precise amount of fuel/air to each cylinder. The result is easy starts and instant throttle response with superior fuel efficiency.
Extreme Duty Gearcase - better durability
The BF200, 225, and 250 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.
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 last day as it is on the first. Learn More
Advanced ECU predicts the user's operation
The technologically-advanced Electronic Control Unit (ECU) in the Honda BF200, 225, and 250 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.
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
2-Pass Cooling System - better cooling for better durability
The unique cooling system maintains an even temperature on all cylinders. The incoming water passes through each aluminum exhaust manifold, then through the cylinder heads and back around the exhaust manifolds before entering the exhaust. This results in increased cooling efficiency and long-term durability!
Positive Lubrication - better durability
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
Sealed Starter - Protection for long life
The starter motor is inverted into a sealed chamber that protects the starter drive from the elements.
Fresh Water Flushport
Flushes debris and saltwater out of the engine, extending the life of the outboard.
Stainless Steel components (Steering Arm, Tilt Tube and all Shafts) - corrosion resistance
Stainless steel components provide durability with long-term corrosion resistance.
Counter Rotation Available
Improves efficiency, hull maneuverability and decreases driver fatigue.
Ultra Low 3 Star CARB Emissions
Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board's standards.
Built-In Pitot Tube
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for speedometer installation.
Reliable, Efficient 4-Stroke Design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
