Honda BF250DURA 250HP – 30″ Shaft Standard Rotation Remote Mechanical

Honda BF250DURA 250HP Mechanical V6

The Honda BF250DURA pairs a 3.6L 24-valve SOHC V6 VTEC engine with standard rotation and traditional remote mechanical controls, at 642 lbs dry. The 30-inch extra-extra-long shaft is engineered for standard right-hand rotation on high-transom offshore vessels, part of Mulmarine’s outboard propulsion systems lineup built for mechanical simplicity.

Peak output runs at 6300 RPM, using PGM-FI for fuel induction and thermal efficiency. The 2.00:1 gear ratio is tuned for a fast hole-shot and hydrodynamic stability in heavy offshore swells. Engineered in Japan, this corrosion-resistant unit includes vibration dampening for a quieter, more comfortable ride.

Technical Specifications of Honda BF250DURA

• The 3.6L V6 SOHC architecture provides strong low-end torque curves under heavy load.
• Standard right-hand rotation gearcase gives efficient hydrodynamic thrust for single-engine installs.
• VTEC optimizes valve timing at high RPM for stronger power and thermal efficiency.
• The 90-Amp alternator maintains battery charge for offshore marine electronics.
• Programmed Fuel Injection (PGM-FI) ensures precise combustion for reliable cold-start reliability.
• Remote mechanical steering compatibility offers a durable, traditional helm feel.
• Power Trim and Tilt allows rapid hull leveling and performance optimization at speed.

VTEC Reliability Tech

This mechanical V6 uses VTEC to maximize air intake at high RPM, giving a versatile power band for trolling and high-speed offshore transit.

PGM-FI System Precision

The fuel induction system manages the air-fuel mixture to optimize efficiency, giving instant throttle response during high-speed coastal runs.

30-Inch Propulsion Shaft

The 30-inch extra-extra-long shaft gives high-transom offshore vessels the reach they need for deep water propeller grip, keeping stability on large deep-V hulls.

NMEA 2000 Integration

NMEA 2000 certification lets captains monitor fuel flow, battery voltage, and RPM in real time.

Honda Factory Coverage

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

Center Console Hull Match

This 30-inch shaft V6 fits large center consoles and pilot house boats, delivering sustained thrust to reach distant fishing grounds.

Maintenance & Longevity

Consistent maintenance of the 3.6L V6 oil level and filter quality is essential for engine health. Pro Tip from the Shop: inspect the mechanical shift and throttle cables every 100 hours for tension and lubrication.
