A Portable Powerhouse
For smaller 12' to 16' boats, the Honda BF20 is as convenient as you can get. At just 104 lbs., it's among the lightest in its class. Yet it's all Honda DNA, quiet, reliable, fuel efficient, and loaded with features. All BF20 outboards feature fully regulated charging systems and harnesses. With the largest alternator in their class, you'll have plenty of power for all your electronics, even when trolling. They also offer Auto Start Enrichment to ensure easy starting and quick warm-up. Add in shallow water drive, power tilt, and much more, and you've got the ideal combination of power and portability.
Reliable, Efficient 4-Stroke Design
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
Large Displacement For Better Performance
At 21.5 cubic inches, the BF20 has one of the largest displacements in its class. Along with the long-stroke design, this provides optimum torque throughout the RPM range.
The lightest 4-stroke model in its class, the BF20 is easy to transport and convenient to mount.
True 5-Year Warranty For Unmatched Peace Of Mind
Honda's True 5 Warranty is the best in the business. This transferable, non-declining warranty is the same on the first day as it is on the last.
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.
4-Front Corrosion Protection System Fights The Elements
A patented, "Double-Sealed" multi-layered paint process, sacrificial anodes, stainless steel technology, and waterproof connectors enhance corrosion protection.
Longer Tiller Handle For Improved Control
A convenient, longer tiller handle improves control and reduces steering effort. The extended handle is made of a lightweight composite, increasing its durability while decreasing the motor's weight.
3-Stage Carburetion For Better Fuel Economy
Conventional 2-circuit carburetors go directly from a lean mixture at idle to a rich setting at full throttle. The BF20 adds a third stage for better economy and smoother operation.
Conveniently tilts the engine out of the water for easy lift-off and transport. At low speeds it acts like a power shallow-water-drive device, permitting access to shallow water areas.
PGM Ignition For Optimal Operation
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range. This provides optimum overall operation.
Engine Alert System Keeps You Informed
The integrated warning system protects the engine from severe damage due to low oil, over-revving, and overheating.
The BF20 has the largest alternator in its class. These motors generate 12 amps at only 3000 RPM. This helps to maintain the battery charge or keep electronics going, even at trolling speeds.
Auto Start Enrichment For Easy Starts
Auto Start Enrichment acts as an automatic choke. Just like a fuel injection system, it automatically adjusts the air/fuel mixture for quick, easy starting and warm-up.
Pendulum Mount System For Smooth Operation
Honda's exclusive triangulated rubber mount system absorbs vibration and provides unbelievably smooth operation.
EZ Steer Friction Control
A unique lever design allows you to precisely adjust steering tension for improved control and comfort.
Shallow Water Drive
An innovative shallow water drive feature lets you tilt the motor up, allowing you to easily operate in shallow areas. Shallow water drive greatly reduces the risk of engine damage.
Up Front Tiller Controls For Convenient Shifting
The convenient front-mounted shift lever allows fingertip shifting. The Twist Grip Throttle & Tensioner minimize driver fatigue.
Integrated Carrying Handle For Easier Transport
An integrated carrying handle makes transporting the engine a breeze. The convenient, foldaway carry handle is situated at the exact top/bottom balance point of the engine. This means the engine carries more easily in a level position.
Positive Lubrication For Better Durability
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
