Description
Match the Honda BF140AK1XCRA 140HP Outboard to a twin-engine offshore fishing boat that requires a 25-inch shaft, mechanical remote controls, and a port-side counter-rotation unit. Its 2,354 cc inline four-cylinder DOHC engine uses 16 valves and VTEC technology, delivering 140 HP at 5,500 RPM. Honda BF140AK1XCRA is a Signature Silver 4-stroke outboard with Programmed Fuel Injection, electric starting, remote mechanical control, and Power Trim & Tilt. The counter-rotation configuration is intended for the listed twin mechanical setup.
The 485-lb dry weight should be included when calculating total engine weight, transom load, and boat balance. The 25-inch X-long shaft is intended for compatible tall transoms, while the 5,000–6,000 RPM full-throttle range helps guide propeller selection after rigging. A 40-amp alternator supplies 30 charging amps for supported marine electronics and accessories. The listed engine oil capacity is 6.7 L with filter, while gearcase lubricant specifications should be confirmed through the correct Honda documentation.
