Description
Position Honda BF250DK1UCDA on the port side of a twin offshore cruiser when a 30-inch U-long shaft, counter-rotation, and iST digital control are required. Its 3.6-liter, 60-degree V6 engine uses 24 valves and SOHC operation, producing 250 HP at 5,800 RPM. Honda BF250DK1UCDA is a white-finish VTEC 4-stroke outboard with Programmed Fuel Injection, electric starting, Intelligent Shift and Throttle, and Power Trim & Tilt. The listed configuration is intended for dual-engine offshore applications.
The 622-lb dry weight should be included in the combined twin-engine transom, balance, and loading calculations. Its 30-inch U-long shaft provides the reach required by the listed application, while the 5,300–6,300 RPM full-throttle range helps guide propeller setup. A 90-amp alternator supplies 60 charging amps for supported offshore electronics and accessories. The listed oil capacity is 7.8 L, with gearcase service and iST maintenance directed by the applicable Honda manual.
