Honda BF225DXCDA 225HP – iST 25″ Shaft Counter Rotation

Honda BF225DXCDA 225HP iST V6

The Honda BF225DXCDA pairs a 3.6L V6 engine with counter-rotation gearing and advanced iST digital control, at 631 lbs dry. The 25-inch extra-long shaft combined with counter-rotation ensures hydrodynamic balance, an essential part of Mulmarine’s outboard propulsion systems lineup for deep-sea fishing and commercial hulls.

Peak output runs at 6000 RPM, supported by VTEC for optimized fuel induction and combustion. The 2.00:1 gear ratio gives immediate hole-shot capability and consistent hull planing under various payload conditions. Built with Japanese precision, this corrosion-resistant unit includes vibration dampening for a quiet, smooth ride.

Technical Specifications of Honda BF225DXCDA

• The 3.6L V6 SOHC design provides the low-end torque required for heavy offshore boat loads.
• iST gives drive-by-wire precision for effortless vessel management.
• Counter-rotation left-hand drive gives balanced steering torque in dual- or triple-engine setups.
• The 90-Amp alternator delivers 60 Amps of charging to support radar and sonar.
• PGM-FI fuel induction manages combustion for improved fuel economy and reliable cold starts.
• Power Trim and Tilt allows rapid engine positioning to maximize hydrodynamic efficiency in rough seas.
• NMEA 2000 certification ensures engine data displays accurately on navigation screens.

VTEC Power Architecture

The VTEC system shifts cam profiles at high RPM to maximize power and thermal efficiency, holding a flat torque curve under various offshore boat loads.

iST Drive-By-Wire

This iST outboard uses drive-by-wire technology to eliminate mechanical shift cables, giving smooth gear engagement critical for maneuvering large vessels.

Counter Rotation Shaft

The 25-inch shaft pairs with a counter-rotation gearbox to negate steering torque in dual-engine installs, tracking straight with minimal effort.

Advanced Digital Interface

NMEA 2000 certification lets captains monitor fuel induction, RPM, and temperature in real time.

Limited Honda Warranty

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

Offshore Hull Match

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

Maintenance & Longevity

Maintaining oil quality in the wet sump lubrication system is critical for V6 engine endurance. Pro Tip from the Shop: periodically check the iST digital wiring harnesses for wear or salt residue.
