Key Features

• Stroke design, based on the Honda Accord: Based on the Honda Accord engine platform, the BF115 benefits from years of proven Honda engineering and reliability.
• Dual Overhead CAM (DOHC): A powerful, compact 16-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.
• 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.
• 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.
• 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 19% less fuel than its predecessor. (Based on EPA Specific Fuel Consumption Mode.)
• Largest Displacement Engine: At 2354 cc (144 cubic inches), the BF115 has 21% more displacement than any competitor in it’s class. The long-stroke design increases torque to deliver outstanding performance and efficiency.
• Balanced Engine: Twin counter-rotating balancing shafts help minimize internal engine vibrations, thus providing smooth operation throughout the entire rpm range.
• LAF & Knock Sensors: Linear Air Fuel (LAF) and knock sensors help determine correct fuel flow and ignition curve to maximize performance and fuel efficiency.
• Engine Command System: The Engine Command Module receives constant input from 18 sensors located throughout the engine. It determines the correct fuel flow and ignition curve, providing optimum performance.
• 3-Way Cooling System: Three separate cooling systems keep the cylinder heads running cooler for long-term durability.
• Engine Alert System: Uses visual, audio and rpm reduction circuits to alert the operator of overheating, low oil PSI, over-revving, water in fuel, battery condition, and critical engine functions.
• Four-Front Corrosion Protection: A patented, “Double Sealed” multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors and painted interior cooling passages, all enhance corrosion protection.
• Fresh Water FlusHPort: Flushes debris and saltwater out of the engine, extending the life of the outboard.
• Stainless Steel (Steering Arm, Tilt Tube and All Shafts): Stainless steel components provide durability with long-term corrosion resistance.
• 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.
• Warranty: As a testament to their quality and reliability, all Honda engines come with a three-year, non-declining, non-commercial warranty or a one-year commercial warranty.
• NMEA 2000 Protocols: NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as sonar or GPS.
• High-Output Charging: The system develops 55 total amps, which after self consumption, delivers 40 “charging” amps. 30 amps at 1000 rpm and 40 amps above 2000 rpm.
• Variable Speed Trolling: Another great advantage for fisherman is the 115’s optional push-button variable speed trolling control. Simply push up or down in 50 rpm increments from 650 rpm to 900 rpm.
• Easy Maintenance: An easy “screw-type” valve adjuster system requires no shims and reduces maintenance costs. Front-mounted oil filter and oil filler make for easy maintenance.
• Built-in Pitot Tube (optional built-in Pitot Tube kit required): Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation.
