Honda BF140AK1XDA 140HP Outboard – 25in Shaft, iST, Drive-by-Wire

Install the Honda BF140AK1XDA 140HP Outboard when a modern offshore center console needs a 25-inch shaft and iST digital control with standard rotation. Its 2,354 cc inline four-cylinder DOHC engine uses 16 valves and VTEC technology, producing 140 HP at 5,500 RPM. Honda BF140AK1XDA is a Grand Prix White 4-stroke outboard with Programmed Fuel Injection, electric starting, Intelligent Shift and Throttle, and Power Trim & Tilt. The standard-rotation layout is intended for compatible single-engine or standard-rotation digital installations.

At 485 lbs dry, this model requires careful attention to transom strength, repower balance, and total boat loading. The 25-inch X-long shaft suits boats with taller transoms, while the 5,000–6,000 RPM full-throttle range offers a practical reference for final propeller selection. The 40-amp alternator supplies 30 charging amps for supported navigation systems, lighting, pumps, and other onboard equipment. The listed engine oil capacity is 6.7 L with filter, with gearcase service directed by the applicable Honda manual.
