Honda BF225DK1UCRA 225HP – 30″ Shaft Counter Rotation Remote Mechanical

Honda BF225DK1UCRA 225HP Mechanical V6

The Honda BF225DK1UCRA pairs a 3.6L 24-valve SOHC V6 engine with counter-rotation gearing and mechanical controls, finished in silver at 642 lbs dry. The 30-inch extra-extra-long shaft is engineered for counter-rotation left-hand operation on deep-V transoms, part of Mulmarine’s outboard solutions lineup built for mechanical reliability.

Peak output holds between 5000-6000 RPM, using PGM-FI for thermal efficiency. The 2.00:1 gear ratio is tuned for a fast hole-shot and hydrodynamic stability in offshore conditions. Built with Japanese precision, this unit includes vibration dampening for a quieter ride in rough saltwater.

Technical Specifications of Honda BF225DK1UCRA

• The 3.6L V6 SOHC design provides the displacement needed for high-torque offshore performance.
• Counter-rotation left-hand rotation enables balanced handling in dual-engine deep-sea configurations.
• Programmed Fuel Injection (PGM-FI) ensures precise fuel induction for reliable cold-start operation.
• Power Trim and Tilt allows rapid engine positioning to improve hull planing efficiency.
• The 90-Amp alternator supports heavy-duty marine electronics and high-draw navigation lighting.
• VTEC maximizes power output by shifting cam profiles at high operational RPMs.
• Remote mechanical steering compatibility gives a traditional, reliable feel.

V6 VTEC Architecture

This mechanical outboard uses VTEC to optimize valve timing for a flat torque curve, staying responsive whether trolling or running at wide-open throttle.

Fuel Induction Efficiency

The fuel induction system uses PGM-FI to monitor engine vitals for optimal combustion, enhancing thermal efficiency and reducing consumption during long transits.

Propulsion Shaft Engineering

The 30-inch shaft gives the reach high-transom offshore vessels need for counter-rotation setups, balancing steering torque in multi-engine arrays.

Digital Data Interface

This V6 is NMEA 2000 certified for real-time monitoring of fuel flow, RPM, and engine temperature.

Honda Factory Coverage

This engine includes a 5-year limited warranty for peace of mind.

Dual Engine Application

As a counter-rotation unit, it pairs with a standard-rotation engine on large tenders, delivering sustained thrust for offshore swells.

Maintenance & Longevity

Regular oil changes within the 3.6L V6 architecture are essential for mechanical longevity. Pro Tip from the Shop: check the mechanical shift cables for proper tension and lubrication every 100 hours.
