BF225 Honda Outboards

Amongst the most powerful 4-stroke engines ever built. Honda's revolutionary BF225 features a compact 60° V6, 3.5 litre engine with 24 valve, Multi Point sequential fuel injection and Variable Air Intake System.

For the first time in the marine industry, Honda's VTEC (Variable Valve Timing and Lift Electronic Control) system has been applied. Its use in the BF225 ensures optimum performance for smooth power delivery and flatter torque curve. The result is consistent acceleration and power in all conditions.

The heart of the BF225 is Honda’s Engine Control Module. This manages all engine functions such as the variable air intake, ignition timing and idling speed. It also pilots the engine alert system in case of low oil pressure, over-heating, over-revving and water contamination in fuel for total worry-free boating.

Standard features on the BF225 is an air feedback sensor and Honda's industry exclusive Lean Burn Feedback System. This reduces fuel consumption by five per cent over the previous models. Furthermore according to internal factory tests, fuel consumption is reduced by 14% over direct injection 2-stroke models and 10% over competing 4-stroke models.

Alternator output is the highest amongst its competitors. It provides "on demand" 60 amps, enough to run all necessary electronic equipment on board, while using less crankshaft horsepower.

Thanks to the 60 degree V6 engine and its sleek streamline design, the BF225 will suit a broad variety of boats, in single or twin applications.

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.

Technology:

• World Famous Quality. By sharing many components with the Honda Odyssey automobile, the BF225 gains years of proven Honda engineering and reliability
• Large Displacement 3.5 Litre 60° V6.A powerful, compact 24 valve SOHC design. Lacking the bulk and weight of long intake runners and multi-camshafts, the narrow V6 design offers all the performance and durability based on Honda automotive engineering excellence
• VTEC. 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.  VTEC offers a superior blend of power, torque and fuel efficiency.
• VTEC racing technology combined with our exclusive dual stage induction produces a longer, flatter torque curve for max power at every speed
• 4-Front Corrosion Protection. A patented, “Double Sealed” multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection 
• 2-Pass Cooling System. The unique cooling system maintains an even temperature on all cylinders. The incoming water passes through each aluminium exhaust manifold, then through the cylinder heads and back around the exhaust manifolds before entering the exhaust. This results in increased cooling efficiency and long-term durability!
• Tuned Dual Exhaust. The competition's exhaust track goes through the middle of the oil pan, pre-heating the oil. Honda's dual exhaust headers wrap around the outside of the oil pan, which not only reduces heat build-up, but also increases engine efficiency and performance!

 

Performance/Usability:

• Engine Command System. The ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and excellent fuel efficiency
• Dual Stage Induction. Honda's variable intake system utilises a plenum chamber with twin butterfly valves to control the volume of intake air into the combustion chambers.  The result is a simple, compact design that improves overall operation
• Even at the largest displacement in its class it also features the lowest idle speed, 650rpm
• Patented non-linear mounting provides smoother operation at all engine speeds
• Fresh water flushport allows easy freshwater flushing of the engine, extending the life of the outboard
• Standard extra long and ultra long shaft lengths allow for a wider range of boat applications. Counter rotation models also available for dual installations
• Lean Burn Feedback Control. Utilises a Linear Air-Fuel Sensor, along with the Engine Command Module, to automatically adjust the air-fuel mix according to speed and load – maximising power throughout the RPM range and providing 20% greater fuel economy in the cruise mode from 2000 to 4500 RPM Inclusion of Lean Burn Feedback Control offers 14% improved fuel consumption over Direct Injection 2-stroke models and 10% over competing 4-stroke models

 

Peace of Mind:

• “On Demand” 60 Amp, belt-driven alternator reduces heat build up and provides superior batter charging capability. 48 Amps at trolling speed!
• Engine Alert System. With Honda’s Engine Alert System, the ECM monitors vital engine functions and prevents engine damage by alerting the operator of overheating, low oil pressure, water in fuel, battery condition and critical engine functions
• Environmental Performance.The BF200 achieves outstanding clean exhaust performance that exceeds both the U.S EPA 2006 and CARB emission regulations for 2008 -the most stringent emissions standards in the world.
• Voluntary Emission Labelling Scheme (VELS) based on international emission regulations to assist the consumer in making better informed choices when purchasing an outboard engine.
• 5 year warranty
