ULTIMATE PERFORMANCE
The new Honda 40hp outboard engine retain 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 in class, the list goes on. Tick all the boxes with the new Honda BF40.
COMPACT INNOVATION
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).
Winning Design
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.
