When you’re chasing horizons, you want an outboard that delivers optimum performance and peace of mind. Which is why you want the Honda BF135 and BF150. These engines created the benchmark for a new generation of marine engine technology, and they’re the choice of center console, catamaran, pontoon, and bay boat owners across the country.
Both motors feature advanced Dual Overhead Cam, in-line four-cylinder architecture, a benefit from decades of Honda automotive and racing experience. Racing experience means more horsepower and instant throttle response. Honda’s exclusive Dual-Stage Induction delivers top performance at every rpm range. And Lean Burn Control automatically adjusts the air-fuel mix to maximize power and fuel efficiency.
All of which makes it clear: when it comes to boating, nothing beats the fuel efficiency and precision standards of Honda.
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
By sharing many components with the Honda Accord, and CRV automobiles, the BF135 and BF150 gain years of proven Honda engineering and reliability.
Featured on the BF150, 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.Learn More
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.Learn More
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.
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.
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.
NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as sonar or GPS.
Honda's True 5 Warranty is the best in the business. This transferable, non-declining warranty is the same on the last day as it is on the first.Learn More
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.Learn More
The ECM monitors vital engine functions and prevents engine damage by alerting the operator of:
The BF135 and BF150 offer optional push-button variable speed trolling control. Simply push the toggle switch to adjust the trolling speed in 50 RPM increments from 650 RPM to 1000 RPM.
A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.Learn More
The ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and excellent fuel efficiency.
Linear Air Fuel (LAF) and knock sensors help determine correct fuel flow and ignition curve to maximize performance and fuel efficiency.
Counter rotating models are available for multiple engine applications. These models improve efficiency, hull maneuverability and decreases driver fatigue.
Three separate cooling systems keep the cylinder heads running cooler for long-term durability.Learn More
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
A single front-mounted latch combines with 4 securing points to ensure a water-tight seal.
The starter motor is inverted into a sealed chamber that protects the starter drive from the elements.
Flushes debris and saltwater out of the engine, extending the life of the outboard.
Stainless steel components provide durability with long-term corrosion resistance.
Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board's standards.
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation.
