BF150 Honda Marine Engine

INTRODUCTION

The BF150 sets a new standard in innovation. With smooth, stable idling, reduced fuel consumption and incredible top-end power, this engine really is in a league of its own.

Performance and Efficiency

4-Stroke Design

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

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.

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.

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 Overhead CAM (DOHC) – High horsepower, low maintenance

A powerful, compact 24-valve DOHC design creates more valve lift to pull in more air for increased horsepower. Low-maintenance design allows easy adjustment of the rocker arms. No multiple shims or trial-and-error adjusting needed.

Engine Command Module – Optimum performance

The ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and excellent fuel efficiency.

LAF & Knock Sensors – Optimum Efficency

Linear Air Fuel (LAF) and knock sensors help determine correct fuel flow and ignition curve to maximize performance and fuel efficiency.

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

Counter rotating models are available for multiple engine applications. These models improve efficiency, hull maneuverability and decreases driver fatigue.

Reliability and Durability

Based on Honda Accord, CRV, and Element

By sharing many components with the Honda Accord, CRV and Element automobiles, the BF150 gains years of proven Honda engineering and reliability.

3-Way Cooling System – Cool running durability

Three separate cooling systems keep the cylinder heads running cooler for long-term durability.

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

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

Superior Battery Charging – More usable power

Honda’s proven “on demand” 51 amp belt-driven alternator reduces heat buildup and provides superior battery charging capability – 30 amps at 1000 RPM and 40+ amps above 2000 RPM.

Built-In Pitot Tube

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

Available in 20 and 25 inch shaft lengths
