Equip Honda BF40DK4LHC on a 20-inch-transom aluminum fishing boat or work skiff when fuel injection, tiller control, and 40 HP are required together. Its 808 cc inline three-cylinder SOHC 4-stroke engine uses 12 valves and Programmed Fuel Injection. Honda BF40DK4LHC is an electric-start outboard with a tiller handle, gas-assist tilt, BLAST, Lean Burn Control, and NMEA 2000 compatibility. The long shaft suits compatible heavy aluminum hulls.

At approximately 216 lbs dry, this model should be included in transom and total boat-loading calculations. The 5,000–6,000 RPM full-throttle range provides a reference for propeller setup, while the 2.08:1 gear ratio supports standard forward, neutral, and reverse operation. Its 22-amp alternator supplies 17 net charging amps for supported electronics and accessories. Confirm the boat’s horsepower rating, transom height, battery requirements, and installation limits before purchase.
