Compact & powerful

With a high output 350cc displacement and long-stroke design, the BF20 is a top performer, providing optimum torque at any speed. Programmed Ignition (PGM-IG) also accurately controls ignition timing during start-up and across the entire rev range for optimum overall operation.

A 12amp (electric start) alternator also ensures excellent charging power to keep batteries in top condition. Thanks to its incredibly lightweight design, the BF20 is also very easy to transport, a foldaway handle positioned at the exact balance point of the engine makes it easy to carry in a level position.

World's largest engine manufacturer


Honda exclusive technology

Engineered for life

More time on the water

Lightweight portable power

Easy to transport

Reverse exhaust relief

Exhaust gases are diverted away from the propeller while in reverse, allowing the propeller to run in clean water.

Easy one hand starting

Working together, a built-in decompression release and Digital CDI system set the ignition timing during start-up. Just 60% of the normal effort is required to pull-start the engine by hand! Electric-start models offer Auto Start Enrichment which automatically adjusts the air/fuel mixture for an even quicker, easy starting and warm-up operation. The PGM Ignition (where a reliable microprocessor accurately controls ignition timing during start-up and across the entire rpm range) provides optimum overall operation. There is also a Power Thrust Option Available too.
