POWERFUL PERFORMANCE.

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.

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.

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.
