BF225

Introduction

Honda’s flagship outboard series – the BF175/200/225 – has undergone a series of minor model changes which will continue to push the boundaries in achieving the world’s highest standard in outboard performance.

The latest generation of large-displacement V6 four-stroke EFI outboards has been reworked and refined to deliver more torque, even greater fuel efficiency, incorporate NMEA 2000 compatibility (engine-to-electronics data communication) and other advantages.

The incorporation of Honda’s revolutionary Boosted Low Speed Torque (BLAST™) air/fuel ratio linked ignition timing control technology delivers explosive hole shot performance to get boats on the plane quicker than ever. Activated by sudden throttle movement, BLAST makes available the greatest amount of torque at the precise moment it’s required.

Reducing fuel consumption by five per cent over the previous BF225 was achieved by adopting a combination of an O-2 feedback system and simple lean burn system – a first in the outboard industry. Known as ECOmo (Economy Controlled Motor), the system is activated when the engine is in mid-range cruising rpm and the throttle is steady. Extensive testing concludes the resultant fuel efficiency is equivalent to that of Honda’s BF150 linear air-fuel (LAF) lean burn system.

Among other notable changes, a new gearcase – with a dramatically more hydrodynamic profile – reduces water resistance and improves acceleration, and a new water intake screen provides better cooling for maximum motor efficiency. A freshly-designed anti-cavitation plate also reduces engine splash, while additional sacrificial anodes ensure increased corrosion resistance for extended durability.

VTEC Technology

Available on the BF225 and derived from our racing heritage, Honda’s Variable Valve Timing and Lift Electronic Control system (VTEC) achieves the best of both worlds by utilising mild cam lobes to operate the intake valves at low RPM-then, at 4,500 RPM, engaging a “high output” cam lobe for high RPM operation, ensuring smooth power delivery throughout the engine’s entire operating range.

Minimum Consumption

The BF225 consumes up to 50% less fuel than conventional 2-stroke engines thanks to Honda’s exclusive Programmed Fuel Injection and Lean Burn Feedback systems, which optimise the air-fuel ratio so you get the maximum performance out of every drop.
