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 miniaturised 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, emphasising the design concept of slimness and strength.


Available as an option, the multi-function tiller handle for the BF40 incorporates a power trim-tilt switch in the throttle grip, so the operator can trim the engine while underway with a clear focus on the water.

An integrated engine alert panel provides both visual and audible alerts including oil pressure, overheating, engine management and battery charging to ensure peace of mind.


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.
