Honda Marine once again raised the performance bar with the BF20 outboard 4-stroke engine, the perfect portable power choice for inflatable yacht tenders, small fishing boats, pontoon boats, or as backup power on larger fishing boats or sail boats. Weighing only 46kgs, the BF20 is the first 4-stroke outboard of its kind to weigh less than most of the other 10 horsepower motors on the market today.
The best boating depends on the right start, ease of maintenance, and maximum time on the water,” said Robin Senger, Honda Marine Marketing. “With the BF20 engine, the integration of easy starting, power and portability make these models popular choices for many different applications.”
In addition to being incredibly lightweight, the BF20 delivers both ease of maintenance and transport. With a long-stroke design and class-leading 350 cc (21.4 cu. in.) displacement, the BF20 is a top performer, providing optimum torque throughout the rpm range. Additionally, an integrated carrying handle, easy one-hand starting and programmed ignition are offered as standard features.
The BF20 engine shares a number of features and benefits that makes this products the most technologically advanced in its class. The 4-Stroke Engine Design combines proven reliability and superior fuel efficiency, with no oil mixing. A PGM Ignition accurately controls ignition timing during start-up, providing optimum overall operation across the entire rpm range, while the Auto Start Enrichment feature automatically adjusts the air-fuel mixture for quick, easy starting and warm-up. In addition, the Engine Alert System is an integrated warning system that protects the engine from severe damage due to low oil, over-revving and overheating.
A Foldaway Carrying Handle positioned at the exact top/bottom balance point of the BF20 engine enhances portability, and makes it easy to carry the engine in a level position. As with other Honda Marine engines, a Fresh Water Flushport works to flush debris and saltwater out of the engine and the patented 4-Front Corrosion Protection System features a double sealed multi-layered paint process.
For increased control and reduced steering effort, the BF20 engine is designed with Longer Tiller Handles made of a new lightweight composite for increased durability and weight reduction. Another unique lever design – the EZ Steer Friction Control – allows the operator to precisely adjust steering tension for improved control and comfort.
Finally, a Shallow Water Drive (on manual trim models) allows boaters to run in shallow water while greatly reducing the risk of engine damage, while Positive Lubrication ensures critical engine component long-term durability.

A Closer Look at Power Thrust
The BF20 engine is equipped with the Honda exclusive Power Thrust Design for enhanced performance and manoeuvrability. It also features Reverse Exhaust Relief, an additional exhaust outlet above the cavitation plate allowing the prop to run in clean, exhaust-free water. The ultimate result is more thrust.
Honda Exclusive Design Elements
The BF20 engine features a number of Honda design exclusives, including:
- Large Displacement, which provides optimum torque throughout the rpm range; the BF20, at 21.4 cubic inches, has the largest displacement in its class.
- Lightweight Design allowing for easy transport and convenient mounting to the hull.
- High Output Charging (the BF20 has the largest alternator in its class).
