Honda BF225DUDA 225HP Outboard – 30in Shaft, iST, Drive-by-Wire, V6, VTEC

Place Honda BF225DUDA on a digital-ready offshore center console or cruiser when a 30-inch U-long shaft and standard-rotation iST control are needed. Its 3.6-liter V6 engine uses a 60-degree layout, 24 valves, and SOHC operation to produce 225 HP at 5,500 RPM. Honda BF225DUDA is an iST drive-by-wire 4-stroke outboard with Programmed Fuel Injection, electric starting, Intelligent Shift and Throttle, and Power Trim & Tilt. The configuration is intended for compatible high-transom digital installations.

At 622 lbs dry, this engine should be included in transom, repower, trailer, and total boat-balance calculations. The 30-inch U-long shaft provides the listed reach for high-transom boats, while the 5,000–6,000 RPM full-throttle range gives owners a reference for propeller selection. Its 90-amp alternator supplies 60 charging amps for supported navigation displays, pumps, lighting, batteries, and communication equipment. The listed oil capacity is 7.8 L with filter.
