Honda BF40 and BF50 EFI: Quick Review

Honda Marine's BF40 and BF50 EFI provide the perfect balance of powerful acceleration and best-in-class fuel efficiency for fresh and salt water applications.

The duo's in-line 3-cylinder engine features Electronic Fuel Injection as well as several Honda-exclusive technologies. Honda's patented Boosted Low Speed Torque (BLAST) system advances ignition timing for explosive "hammer-down" acceleration, while Lean Burn Control adjusts the air/fuel mixture for maximum fuel efficiency at cruise.

The lightest engines in their class, the 214-pound BF40 and BF50 EFI feature a lightweight, 22-amp alternator that offers best-in-class 17-amp charging capacity for multiple electronic accessories.
