Powerful 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.


Superior Fuel Efficiency

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.


Legendary Reliability

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.


Easy Ownership

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.


Fishing Friendly Tiller

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.


Attractive Options

Variable Trolling Speeds

An optional switch allows for variable trolling speeds, ideal for fishermen.
