Install the Honda BF140AK1XDA 140HP Outboard on a digital-ready offshore center console that requires a 25-inch shaft and standard rotation. Its 2,354 cc inline four-cylinder DOHC engine uses 16 valves and VTEC technology, producing 140 HP at 5,500 RPM for properly rated recreational hulls. 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 iST installations.

At 485 lbs dry, this model should be included in transom strength, repower, and boat-balance calculations. The 25-inch X-long shaft suits boats with taller transoms, while the 5,000–6,000 RPM full-throttle range provides a reference for propeller selection. The 40-amp alternator supplies 30 charging amps for supported navigation systems, pumps, lighting, and other equipment. Engine oil capacity is listed at 6.7 L with filter; gearcase service should follow the applicable Honda manual.
