The BF40 and BF50 outboard engines retain their class-leading lightweight, compact packaging, enhanced with PGM-FI electronic fuel injection, Honda’s original Boosted Low Speed Torque (BLAST™) air/fuel ratio and ignition-timing technology, and lean burn control to deliver powerful startup and acceleration together with outstanding fuel economy during cruising (ECOmo).


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 and BF50 feature a striking ‘wing form’ design, emphasising the design concept of slimness and strength.
