Features

Features

  • VTEC® - SMOOTH ACCELERATION AND POWER: Featured on the BF140, 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.
  • 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.
  • DUAL STAGE INDUCTION - BREATHING EASIER IMPROVES PERFORMANCE: The BF140 is equipped with Dual Stage Induction to maximize air input for combustion.
  • DUAL OVERHEAD CAM (DOHC) - HIGH HORSEPOWER, LOW MAINTENANCE: A powerful, compact 24-valve DOHC design creates more valve lift to pull in more air for increased horsepower. Low-maintenance design allows easy adjustment of the rocker arms. No multiple shims or trial-and-error adjusting needed.
  • LEAN BURN CONTROL® - SUPERIOR FUEL EFFICIENCY: 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.
  • 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.
  • SIMPLIFIED MAINTENANCE: The little things make a big difference. The BF140 is designed to reduce maintenance time for routine tasks like oil and filter changes.
  • ENGINE ALERT SYSTEM - KEEPS YOU INFORMED: The ECM monitors vital engine functions and prevents engine damage by alerting the operator of: Overheating, Water in Fuel, Low Oil PSI, Battery, Over-Rev, Critical Engine Function.
  • IMPROVED CORROSION RESISTANCE: Repositioned anodes and a new bolt coating boost corrosion resistance
  • 4-FRONT CORROSION PROTECTION SYSTEM - FIGHTS THE ELEMENTS: A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.
  • NMEA 2000 - ON-BOARD CONNECTIVITY: NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as sonar or GPS.
  • PROVEN HONDA QUALITY: Our outboards share many technologies and components used in Honda vehicles, with all the benefits of years of proven Honda engineering, precision manufacturing and reliability.
  • TRUE 5 WARRANTY: 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.
  • SUPERIOR BATTERY CHARGING - MORE USABLE POWER: Honda's proven "on demand" 55 amp belt-driven alternator reduces heat buildup and provides 40 amps of battery charging capability.
  • ENGINE COMMAND MODULE - OPTIMUM PERFORMANCE: The ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and excellent fuel efficiency.
  • 3-WAY COOLING SYSTEM - COOL RUNNING DURABILITY: Three separate cooling systems keep the cylinder heads running cooler for long-term durability.
  • CONVENIENT SINGLE LATCH COWL: A single front-mounted latch combines with 4 securing points to ensure a water-tight seal.
  • FRESH WATER FLUSHPORT: Flushes debris and saltwater out of the engine, extending the life of the outboard.
  • 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.
  • COUNTER ROTATION AVAILABLE: Counter rotating models are available for multiple engine applications. These models improve efficiency, hull maneuverability and decreases driver fatigue.
  • Available in 20 and 25 inch shaft lengths
