Honda BF250DK1XCDA 250HP – iST 25″ Shaft Counter Rotation in Silver

Honda BF250DK1XCDA 250HP iST V6

The Honda BF250DK1XCDA pairs a 3.6L 24-valve SOHC V6 VTEC engine with counter-rotation gearing, finished in silver at 631 lbs dry. The 25-inch extra-long shaft is engineered for hydrodynamic balance in multi-engine offshore center consoles, part of Mulmarine’s outboard propulsion systems lineup.

Peak output holds between 5300-6300 RPM, using PGM-FI for thermal efficiency and high-end throttle response. The 2.00:1 gear ratio is tuned for immediate hole-shot and stability in choppy saltwater. Built with Japanese engineering, this outboard includes vibration dampening for a quieter, smoother ride during offshore missions.

V6 VTEC Technology

This iST outboard uses VTEC to shift cam profiles at high RPM, maintaining a flat torque curve for sustained power navigating difficult coastal inlets.

iST Digital Control

The iST system removes mechanical cables for drive-by-wire control, giving smooth gear engagement and precise throttle adjustments.

25-Inch Counter Shaft

The 25-inch extra-long shaft’s counter-rotation gearbox negates steering torque in dual-engine installs, minimizing drag while maximizing thrust in heavy swells.

Fuel Induction Precision

The fuel induction system manages the air-fuel mixture precisely, giving instant hole-shot performance and consistent power at high speed.

Honda 5-Year Warranty

Honda Marine backs this unit with a 5-year limited warranty covering major components against manufacturing defects.

Multi-Engine Hull Match

This counter-rotation V6 fits dual-engine offshore center consoles and walkaround vessels, delivering sustained thrust for heavy swells.

Maintenance & Longevity

Routine maintenance of the 3.6L V6 cooling system prevents internal salt corrosion. Pro Tip from the Shop: inspect the iST digital harness connectors for salt residue every 50 hours to ensure flawless communication.
