BF50

THE ALL ACHIEVER IN A SMALL FORM FACTOR

The BF50 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 unparalleled features and technology.

Like BLAST (Boosted Low Speed Torque) for vastly improved hole shots. Programmed Electronic Fuel Injection, for easy starts, instant throttle response, 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 l find that the BF50 isn’t just at the head of the class. They’re in a class by themselves, redefining mid-range four-stroke performance.

POWERFUL PERFORMANCE

INSTANT ACCELERATION

Honda’s exclusive BLAST system improves acceleration at low speeds. The result? Instant acceleration and improved hole shot.

MIKUNI® INTAKE SYSTEM

The lightweight Mikuni® long tube intake track system helps build low end torque.

HIGH PERFORMANCE GEARCASE

Designed to get you going faster, the BF50’s gearcase reduces drag, greatly reduces hull porpoise and minimizes spray, increasing acceleration and top speed.

LIGHTWEIGHT AND COMPACT

Because of Honda’s elegant design, the BF50 IS 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.

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

EASY MAINTENANCE

Easy access side-mounted oil filter and oil fillers simplify maintenance, while “screw-type” valve adjusters reduce maintenance costs.

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 50 to put out nearly twice as many charging amps as the competition’s.

ON-BOARD CONNECTIVITY

NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as SONAR or GPS..
