Honda BF40DK4LHC 40HP 4-Stroke Outboard – 20in Shaft, Tiller

Equip Honda BF40DK4LHC when a 20-inch-transom workboat or 15- to 17-foot fishing hull needs 40 HP with direct tiller control. Its 808 cc inline three-cylinder SOHC 4-stroke engine uses 12 valves and Programmed Fuel Injection. Honda BF40DK4LHC is a portable-style outboard with electric starting, a tiller handle, gas-assist tilt, BLAST, Lean Burn Control, and NMEA 2000 compatibility. The long shaft suits compatible heavy aluminum boats and work skiffs.

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