Honda BF15 BF20 Outboards

For smaller 12 to 16 foot boats, the BF15 and BF20 are as convenient as you can get. At just 104 pounds, they are among the lightest in their class. Yet they‘re all Honda DNA: quiet, reliable, fuel efficient, and loaded with features. Like the highest output charging system in their class, giving you plenty of power for all your electronics, even when trolling.

Or large displacement for a powerful performance. Choose the BFP Power Thrust design for even more boost, with 60% more thrust in reverse and 15% more in forward. Add in easy one hand starting, shallow water drive, power tilt, and much more, and you’ve got the ideal combination of power and portability.
