The Honda BF140AXDA represents Honda’s advanced 4-cylinder outboard engineering, delivering robust 140 horsepower through a sophisticated 2.4-liter DOHC 16-valve engine designed for diverse marine applications. The 25″ extra-long shaft configuration makes this outboard ideal for a wide range of vessels including bay boats, center consoles, and sportfishing boats with standard to deeper transoms requiring extended shaft length for optimal propeller positioning and performance.
The revolutionary iST® (Intelligent Shift and Throttle) drive-by-wire system provides instantaneous electronic throttle response and seamless shifting, eliminating traditional cable lag for enhanced boat handling and maneuverability. This advanced system supports up to four engines and two control stations, featuring user-programmable system defaults, enhanced docking capabilities, and intuitive interfaces that make complex boat handling effortless.
Built upon Honda’s renowned automotive engineering foundation, the BF140AXDA features Honda’s exclusive VTEC® technology that optimizes power delivery across the entire RPM range, delivering explosive mid-range torque when acceleration matters most. The innovative dual stage induction system maximizes air intake for superior combustion efficiency, while BLAST™ technology aggressively advances ignition timing for dramatically improved hole shots and acceleration.
Honda’s legendary reliability shines through with the advanced PGM-FI fuel injection system, ensuring optimal fuel delivery in all conditions while meeting stringent CARB emissions standards. The Lean Burn Control technology delivers exceptional fuel efficiency by optimizing the air-fuel mixture during cruising speeds, providing superior fuel economy compared to competitive engines in its class.
The robust 55-amp alternator provides reliable charging power for today’s electronics-heavy boats, delivering 40 amps of charging power to keep onboard systems operational. The classic Aquamarine Silver finish provides excellent corrosion resistance while maintaining Honda’s distinctive marine aesthetic that has defined quality marine propulsion for decades.
Standard features include power trim and tilt, NMEA 2000® certification for seamless electronics integration without expensive gateway interfaces, built-in speedometer pickup, freshwater flush port, and Honda’s comprehensive corrosion protection system featuring multiple anodes and specialized marine coatings designed to withstand the harsh saltwater environment.
Perfect for offshore fishing boats, high-performance bay boats, and versatile center consoles requiring 25″ shaft length with advanced electronic controls, the Honda BF140AXDA combines proven 4-cylinder reliability with precision drive-by-wire technology and VTEC® performance, delivering the advanced control and dependable operation that serious boaters demand for their marine adventures where electronic precision and proven reliability are essential.
