The BF225 from Honda Marine
This is a Large Displacement V-6 engine in a narrow, sixty-degree "V" profile. The 225's Variable Valve Timing and Lift Electronic
Control (VTEC) is a state-of the- art design that gives this engine a unique blend of power, torque and efficiency at every speed. Take a
look inside at the engineering of this incredible powerhouse.. Honda's 225hp features an "on-demand", 90 AMP alternator that reduces
heat build-up and keeps your battery charged all day, even if you're running multiple accessories. And an oxygen sensor feedback
system refines economy. Compact, computer controlled Dual-Stage Induction makes this engine the standard for reliability. Play the
video to see how this valuable feature works. World Famous Quality, by sharing many components with the Honda Odyssey and Acura
MDX, the BF225 gains years of proven Honda engineering, precision manufacturing and reliability.
Large Displacement V6 - The BF225’s slim 60° profile and 3.5L V6 offer top performance and durability.
Dual Stage Induction - Most 4-strokes use long manifolds to deliver air into the cylinder head. Honda’s variable intake system utilizes
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.
VTEC - Variable Valve Timing & Lift Electronic Control system achieves the best of both worlds, by utilizing mild cam lobes to operate
the intake valves at low RPM — then, at 4500 RPM, engaging a "high output" cam lobe for high RPM operation.
BENEFIT - VTEC offers a superior blend of power, torque and fuel efficiency.
Lean Burn Feedback Control
Utilizes a Linear Air-Fuel Sensor, along with the Engine Command Module, to automatically adjust the air-fuel mix according to speed
and load — maximizing power throughout the RPM range and providing twenty percent greater fuel economy in the cruise mode from
2000 to 4500 RPM.
Dual Stage Induction - Most 4-strokes use long manifolds to deliver air into the cylinder head. Honda's variable intake system utilizes
a plenum chamber with twin butterfly valves to control the volume of intake air into the combustion chambers.
BENEFIT - The result is a simple, compact design that improves overall operation.
Engine Command System - The EMC receives constant input from 18 different sensors and delivers instant starts, smooth operation,
strong performance and excellent fuel efficiency. Oxygen (O2) and Knock Sensors - Oxygen (O2) and knock sensors help determine
the correct fuel flow and ignition curve to maximize performance and fuel efficiency.
High Output Charging - Belt-driven to reduce heat and improve reliability, the BF225’s charging system features a 90 amp alternator
for outstanding battery charging across the RPM range.
Dual Engine Applications -Eliminating the need for expensive transom modifications, the BF225’s slim 60° profile allows for mounting
of dual engines on a 26” center-to-center distance.
Engine Alert - The ECM monitors vital engine functions and prevents engine damage by alerting the operator of:
* Overheating
* Water in Fuel
* Low Oil PSI
* Battery
* Over-Rev
* Critical Engine Function
Balanced Engine - The 60° V6 fires every 60°, offering the best in balance and durability and providing smooth operation throughout
the entire RPM range. 2-Pass Cooling System The unique cooling system maintains an even temperature on all cylinders. The
incoming water passes through each aluminum 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!
Multi-port Programmed Fuel Injection (PGM-FI) - Delivers the precise amount of fuel/air to each cylinder. The result is quick starts,
instant throttle response and low fuel consumption.
Positive Lubrication - A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine
components.
Non-Linear Mounting System - Patented non-linear rubber mounts provide smoother operation at all engine speeds.
Single Latch Cowl - A single front-mounted latch combines with 4 securing points to ensure a water-tight seal.
Sealed Starter - The starter motor is inverted into a sealed chamber that protects the starter bendix drive from the elements.
Corrosion Protection System - A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel
technology, along with waterproof connectors, all enhance corrosion protection.
Fresh Water Flushport - Flushes debris and saltwater out of the engine, extending the life of the outboard.
Stainless Steel (Steering Arm, Tilt Tube and all Shafts) - Durability with long-term corrosion resistance!
Counter Rotation - Improves efficiency, hull maneuverability and decreases driver fatigue.
Built-In Pitot Tube - Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation.
Ultra Low 3 Star Carb Emissions - Cleanest technology available.
