Upgrade a compatible bay boat or sport hull with the Honda BF150DLDA 150HP Outboard when a 20-inch transom needs iST digital control and 150 horsepower. Its 2,354 cc inline four-cylinder DOHC engine uses 16 valves and VTEC technology, producing 150 HP at 5,500 RPM. Honda BF150DLDA is a Grand Prix White 4-stroke outboard with Programmed Fuel Injection, electric starting, Intelligent Shift and Throttle, and Power Trim & Tilt. The 20-inch long shaft suits standard long-transom installations.

The 472-lb dry weight should be included in transom, repower, and boat-balance calculations. The full-throttle range of 5,000–6,000 RPM provides a reference for propeller selection after rigging, while the 2.14:1 gear ratio supports standard forward, neutral, and reverse operation. Its 40-amp alternator supplies 30 charging amps for compatible displays, lighting, pumps, and other electrical accessories. The listed engine oil capacity is 6.7 L with filter, while gearcase service should follow the applicable Honda documentation.
