Honda BF140AK1LRA 140HP Outboard – 20in Shaft, Remote Mechanical, VTEC

Install the Honda BF140AK1LRA 140HP Outboard when a bass boat or aluminum sport hull needs 140 horsepower with traditional remote mechanical controls and a 20-inch shaft. Its 2,354 cc inline four-cylinder DOHC engine uses 16 valves and VTEC technology, producing 140 HP at 5,500 RPM. Honda BF140AK1LRA is a Signature Silver 4-stroke outboard with Programmed Fuel Injection, electric starting, remote mechanical control, and Power Trim & Tilt. The long shaft suits compatible standard transoms.

At 472 lbs dry, this model should be included in the boat’s repower and balance calculations before installation. The 5,000–6,000 RPM full-throttle range provides a useful reference when selecting and checking the propeller. The 2.14:1 gear ratio supports normal forward, neutral, and reverse operation. A 40-amp alternator provides 30 charging amps for supported electronics, lighting, pumps, and accessories. The listed engine oil capacity is 6.7 L with filter.
