The lightweight BF40 3-cylinder engine features a unique set of Honda-exclusive technologies, to deliver exceptional power-to-weight ratio, great acceleration, torque and leading fuel-efficiency. Power your adventures on a wide range of boat types with the BF40! With the included standard rigging kit and propeller, the BF40 is ready to get you out on the water sooner!


The Honda BF40 outboard engine retains its class-leading lightweight, compact packaging, enhanced with PGM-FI electronic fuel injection. It features the innovative BLAST™ (Boosted low speed torque) for rapid acceleration, ECOmo Lean Burn Control® for exceptional fuel economy at cruise and NMEA 2000® which shows all engine and fuel data on a GPS screen.

Lightest in class, most fuel efficient in class, best acceleration, the list goes on. Tick all the boxes with the Honda BF40.


A reduction gear is employed to achieve compact engine layout by offsetting the in-line three-cylinder engine forward, while a long-branch plastic inlet manifold and miniaturized electronic components further contribute to the class-topping lightweight, compact design.  Like Honda’s larger outboard engines, the BF40 features a striking ‘wing form’ design, emphasizing the design concept of slimness and strength.

BOOSTED LOW SPEED TORQUE (BLAST) – Honda’s revolutionary BLAST™ technology provides strong hole shot performance, getting the hull on the plane quicker. This air/fuel ratio and ignition-timing technology boosts engine torque at low RPM under rapid acceleration conditions. It’s NMEA compatible, meaning all engine data including speed, fuel consumption, cruising distance, etc can be displayed on the GPS screen.

CRUISE MORE, SPEND LESS – Honda’s Lean Burn Control technology, ECOmo, permits combustion to operate on a leaner air/fuel ratio. Sensors precisely measure the air/fuel mixture, ensuring best fuel economy in cruising mode.

As a testament to their quality and reliability, all Honda engines come with a SEVEN year, non-declining, non-commercial warranty or a THREE year commercial warranty. Shop around, you won’t find a better warranty set up than Honda Marine.
