BF225 Honda Marine Engine

BF225 Honda Marine Engine
Honda innovation combined with a powerful, large-displacement V6 engine, the BF225 offers the most technologically-advanced power available


Performance and Efficiency

BLAST® System - improves acceleration at low speeds

Boosted Low Speed Torque, or BLAST, improves acceleration at low speeds. A quick movement of the throttle control activates the BLAST® system, advancing the ignition curve aggressively. "Hole Shot" is vastly improved as more horsepower gets the hull up on plane quicker.

4-Stroke Design

World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.

Large Displacement V6

A powerful, compact 24 valve SOHC design, without the bulk and weight of long intake runners and multi-camshafts. The narrow V6 design offers top performance and durability as well as great fuel economy.

VTEC® - Smooth acceleration and power.

Honda’s Variable Valve Timing & Lift Electronic Control (VTEC®) system provides power where and when you need it. VTEC gives you a broader, flatter torque curve and smooth power delivery throughout the engine’s operating range. The result is a superior combination of power, torque and fuel economy. VTEC is the modern replacement for displacement.

Lean Burn Control® - Superior fuel efficiency

Lean Burn Control® increases fuel efficiency by allowing combustion to operate on a leaner air/fuel mixture. At cruising speed, this engine runs on up to 20% less fuel* than others in its class.
*Based on EPA Specific Fuel Consumption Mode.

Dual Stage Induction - Breathing easier improves performance

Honda’s unique variable intake system optimizes air flow to match the engine’s speed. The result? Maximized combustion efficiency, increased torque, and superb fuel economy.

Oxygen (O2) and Knock Sensors - Optimum Efficency

Oxygen (O2) and knock sensors help determine the correct fuel flow and ignition curve to maximize performance and fuel efficiency.

Balanced Engine - Smoother operation

The 60° V6 fires every 60°, offering the best in balance and durability and providing smooth operation throughout the entire RPM range.

Tuned Dual Exhaust - increased efficiency

Some competitor's exhaust tracks 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. This reduces heat build-up, and increases engine efficiency and performance.

Multi-port Programmed Fuel Injection (PGM-FI) - Powerful performance

Programmed Fuel Injection delivers the precise amount of fuel/air to each cylinder. The result is easy starts and instant throttle response with superior fuel efficiency.

Non-Linear Mounting System - Smoother operation

Patented non-linear rubber mounts provide smoother operation at all engine speeds.

Counter Rotation Available

Improves efficiency, hull maneuverability and decreases driver fatigue.

Reliability and Durability

Extreme Duty Gearcase

The BF225 offers a larger, 5 inch diameter gear case, built to withstand the extreme duty cycles of law enforcement and military patrol boats.

Saltwater protection

Honda has painted the interior cooling passages on the BF225. This process prolongs the engine's life in the harsh saltwater environment.

World Famous Quality

The BF225 shares many components with the Honda Ridgeline, Odyssey, Honda Pilot and Acura MDX, gaining years of proven Honda engineering, precision manufacturing and reliability.

Engine Alert System - Keeps you informed

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

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!

Positive Lubrication

A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.

Single Latch Cowl

A single front-mounted latch combines with 4 securing points to ensure a water-tight seal.

Sealed Starter - Protection for long life

The starter motor is inverted into a sealed chamber that protects the starter drive from the elements.

4-Front Corrosion Protection System - Fights the elements

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 components (Steering Arm, Tilt Tube and all Shafts) - corrosion resistance

Stainless steel components provide durability with long-term corrosion resistance.

Ultra Low 3 Star CARB Emissions

Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board's standards.

Convenience and Ease of Use

NMEA 2000 - On-board connectivity

NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as sonar or GPS.

Superior Battery Charging - More usable power

The BF225’s charging system features a 90 amp "On Demand" belt-driven alternator with 60 chargng amps. This superior design reduces heat buildup and provides outstanding battery charging across the RPM range.

Slim 60° profile for dual engine applications

No need for expensive transom modifications! The BF225’s slim 60° profile allows for mounting of dual engines on an industry standard 26” center-to-center distance. Makes repowers easier!

Built-In Pitot Tube

Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for speedometer installation.
