The biggest of the Honda large outboards. With legendary VTEC® technology, the BF250 has outstanding performance and reliability. You also get big power and fuel economy thanks to BLAST® (Boosted Low Speed Torque) and Dual Stage Induction combined with Direct Air Intake System. And with AMP+, you get an industry-first feature that helps prevent the draining of critical battery power when using multiple accessories. |

Performance and Efficiency
|
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. |
Large Displacement V6
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. |
VTEC®
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. |
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. |
Dual Stage Induction
Honda’s unique variable intake system optimizes air flow to match the engine’s speed. The result? Maximized combustion efficiency, increased torque, and superb fuel economy. |
Direct Air Intake System Using 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 system. |
Four-Stroke Design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing. |
Large Air Intake Silencer Reduces Noise
The design of the variable air intake system on the Honda BF250 also includes a large air intake silencer that reduces noise. The silencing effect results from a chamber being added to the intake passage, causing sound waves to interfere with one another – effectively quieting noise. |
Advanced ECU predicts the user’s operation
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. |
Oxygen (O2) and Knock Sensors
Oxygen (O2) and knock sensors help determine the correct fuel flow and ignition curve to maximize performance and fuel efficiency. |
Balanced Engine
The 60° V6 fires every 60°, offering the best in balance and durability and providing smooth operation throughout the entire rpm range. |
Advanced ECU predicts the user’s operation
The technologically advanced Electronic Control Unit (ECU) in the Honda BF225 (starting with K3 models) 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. |
Tuned Dual Exhaust
Some competitor’s exhaust tracks goes through the middle of the oil pan, pre-heating the oil. Honda’s dual exhaust headers wrap around the outside of the oil pan. This reduces heat build-up, and increases engine efficiency and performance. |
Multi-Port Programmed Fuel Injection (PGM-FI®)
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. |
Non-Linear Mounting System
Patented non-linear rubber mounts provide smoother operation at all engine speeds. |
Counter Rotation
Improves efficiency, hull manoeuvrability and decreases driver fatigue. |
Extreme Duty Gearcase
The BF250 features 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. |
