Give Honda BF40D4LHA a place on an aluminum fishing boat or work skiff when 40 HP, a 20-inch shaft, and direct tiller control are required. Its 808 cc inline three-cylinder SOHC 4-stroke engine uses six valves and produces 40 HP at 5,500 RPM. Honda BF40D4LHA is a Signature Silver outboard with Programmed Fuel Injection, BLAST, electric starting, a multi-function tiller handle, and gas-assist or manual tilt. The long shaft is intended for compatible 20-inch transoms.

At 225 lbs dry, this tiller configuration should be included in transom, trailer, and overall boat-balance calculations. The 5,000–6,000 RPM full-throttle range provides a reference for propeller selection, while the 2.08:1 gear ratio supports standard forward, neutral, and reverse operation. Its 22-amp alternator supplies 17 charging amps for supported electronics, lighting, pumps, and accessories. The listed engine oil capacity is 2.1 L with filter, while gearcase lubricant and service intervals should follow the applicable Honda owner’s manual.
