About the BF140A

The Honda BF140 outboard motor represents Honda’s latest advancement in high-performance marine propulsion, introducing the all-new 140-horsepower engine that upgrades the previous BF135 model to deliver enhanced power and efficiency. This sophisticated 4-stroke, DOHC (Dual Overhead Cam) engine features a robust 4-cylinder, 16-valve configuration that produces peak power of 140 horsepower at 5,500 RPM across its 5,000-6,000 RPM operating range.

At the heart of the BF140 lies Honda’s renowned 2,354cc displacement with precision-engineered 87 x 99mm bore and stroke specifications, derived from proven automotive technology tested on racetracks and roadways worldwide. The advanced 16-valve Dual Overhead Cam configuration maximizes high-RPM power delivery while maintaining exceptional fuel efficiency and smooth operation throughout the entire power band.

The BF140 features Honda’s exclusive VTEC® (Variable Valve Timing & Lift Electronic Control) technology, delivering power precisely where and when needed through a broader, flatter torque curve and smooth power delivery throughout the engine’s operating range. Combined with Dual Stage Induction, which maximizes air intake for optimal combustion, this motor provides outstanding performance without compromising efficiency.

Honda’s innovative BLAST™ (Boosted Low Speed Torque) technology aggressively advances the ignition curve for dramatically improved hole shots and faster time to plane. The sophisticated Lean Burn Control system enhances best-in-class fuel economy, while the advanced 3-Way Cooling System ensures optimal thermal management for long-term durability and consistent performance.

The advanced Multi-Port Programmed Fuel Injection (PGM-FI) system delivers precise fuel metering under all operating conditions, ensuring instant throttle response, reliable starts, and optimal consumption. The high-output alternator generates an impressive 55 amps total with 40 amps of charging capacity, easily supporting modern marine electronics and accessories during extended outings.

Available with both traditional mechanical controls and Honda’s cutting-edge iST® (Intelligent Shift and Throttle) drive-by-wire system, the BF140 offers maximum installation flexibility. The iST® system provides superb control with seamless integration capabilities, including compatibility with third-party joystick systems and enhanced docking control for superior maneuverability.

Built to withstand demanding marine environments, the BF140 incorporates Honda’s comprehensive Corrosion Protection system with multi-layered coatings, strategic anode placement, and waterproof connections. NMEA 2000® certification enables direct integration with modern marine electronics, while advanced engine monitoring provides real-time performance data and diagnostic capabilities.

Available in both 20-inch and 25-inch shaft configurations with standard power trim and tilt, including counter-rotation models, the BF140 adapts to diverse vessel requirements. Whether powering sport fishing boats, family cruisers, or performance vessels, the Honda BF140 delivers the perfect fusion of power, technology, and legendary Honda reliability.
