Description
Ready to take you to great places. Like the head of the class. The BF40 L-Type, with a 20 in. shaft, is an outstanding combination of Honda’s legendary four-stroke engineering and our latest outboard innovations. The result? The lightest, most compact engines in their class. And because they are from Honda, they’re loaded with the unparalleled features and technology you want, such as BLAST (Boosted Low Speed Torque). It’s activated by a quick movement of the throttle for vastly improved hole shots; Programmed Electronic Fuel Injection, for easy starts, instant throttle response, slower trolling speeds, and overall better fuel economy; Lean Burn Control stretches your gas even further by allowing a leaner air-to-fuel mixture.
Put it all together, and you’ll find that the BF40 L-Type are not just at the head of the class, It's in a class by themselves, redefining mid-range four-stroke performance.

- Instant Acceleration: Honda’s exclusive BLAST system improves acceleration at low speeds. The result? Instant acceleration and improved hole shot.
- High Performance Gearcase: Designed to get you going faster, the BF40 and 50's gearcase reduces drag, greatly reduces hull porpoise and minimizes spray, increasing acceleration and top speed.
- Mikuni Intake System: The lightweight Mikuni long tube intake track system helps build low end torque, improving performance.
- Lightweight and Compact: Because of Honda’s elegant design, the BF40 and 50 are among the lightest, most compact engines in their class. Perfect for aluminum boats, inflatables, skiffs and flats boats.
- Best in Class 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.
- Pgm-Fi: Multi-port Programmed Fuel Injection adds both easy starts and improved fuel efficiency - without sacrificing performance.
- Tough Corrosion Resistance: Honda’s exclusive 4-Front Corrosion Protection System offers a patented, double-sealed multi-layered paint process.; Fresh water flushport flushes debris and saltwater out of the engine.
- 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.
- Unmatched Peace of Mind: 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.
- Engine Alert System: The Engine Alert System uses visual, audio and RPM reduction circuits to alert the operator of over-heating, low oil PSI and over-revving.
- On-Board Connectivity: NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as SONAR or GPS.
- High Output Charging for More Usable Power: The high output charging system features a 22 amp "On Demand" belt-driven alternator with 17 charging amps. This superior design enables the 40 and 50 to put out nearly twice as many charging amps as the competition’s.
- Easy Maintenance: Easy access side-mounted oil filter and oil fillers simplify maintenance, while "screw-type" valve adjusters reduce maintenance costs.
- 3 Position Tiller Handle: The 3 Position Tiller Handle adjusts to your comfort for easiest hull maneuverability.
- Easy Access Controls: The center mounted, ergonomically designed tiller handle is longer for improved handling. Adjustments for throttle and steering friction allow easier control. Up front shift lever, PTT switch, and engine alert lamps provide added convenience.
- Variable Trolling Speeds: An optional switch allows for variable trolling speeds, ideal for fishermen.
- Power Trim/Tilt: Allows you to trim the unit for maximum performance and handling.
