The Honda BF115 outboard motor represents the entry point into Honda’s high-performance Large Engine Series, delivering exceptional 115-horsepower output through advanced automotive-inspired engineering. This sophisticated 4-stroke, DOHC (Dual Overhead Cam) engine features a robust 4-cylinder, 16-valve configuration that produces peak power of 115 horsepower at 5,250 RPM across its 4,500-6,000 RPM operating range.
Engineered with Honda’s renowned 2,354cc displacement and precision 87 x 99mm bore and stroke specifications, the BF115 delivers outstanding performance and reliability. The 16-valve Dual Overhead Cam configuration maximizes high-RPM power delivery while maintaining smooth operation and exceptional fuel efficiency throughout the entire power band.
The BF115 incorporates Honda’s exclusive BLAST™ (Boosted Low Speed Torque) technology, which aggressively advances the ignition curve for dramatically improved hole shots and faster time to plane. Combined with Lean Burn Control for enhanced fuel economy and the advanced 3-Way Cooling System for optimal thermal management, this motor delivers both performance and efficiency that define best-in-class operation.
Honda’s sophisticated Multi-Port Programmed Fuel Injection (PGM-FI) system ensures precise fuel delivery under all conditions, providing 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 powering modern marine electronics and accessories during extended outings.
Available with both traditional mechanical controls and Honda’s innovative iST® (Intelligent Shift and Throttle) drive-by-wire system, the BF115 offers maximum flexibility for different installation requirements. The iST® system provides superb control with seamlessly integrated installation capabilities, including compatibility with third-party joystick systems for enhanced maneuverability.
Built to withstand demanding marine environments, the BF115 features 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 without expensive gateway devices, while advanced engine monitoring provides real-time performance data and alerts.
Offered in both 20-inch and 25-inch shaft configurations with standard power trim and tilt, the BF115 adapts to various transom heights and vessel requirements. Optional features include tilt limit switches, variable trolling control, and smart key immobilizer for enhanced security and convenience.
Whether powering sport fishing boats, family cruisers, or performance vessels, the Honda BF115 delivers the perfect balance of power, technology, and reliability that Honda Marine is renowned for.
