Honda Outboard Portable Motors 2.3-20HP

Honda Outboard Portable Motors 2.3–20HP

If you’re looking for a small outboard that’s easy to handle, easy to own, and built to run for years without constant fuss, Honda’s 2.3–20 horsepower portable outboards are a solid place to land. These motors are designed for dinghies, inflatables, jon boats, sailboats, and small skiffs—boats where reliability, efficiency, and predictable performance matter more than bells and whistles.

Honda’s approach in this horsepower range is straightforward and practical. These engines are quiet, fuel-efficient, and tuned for smooth power at the speeds small boats actually run. From the ultra-simple BF2.3 you can carry with one hand, up to the EFI-equipped BF20, Honda focuses on durability and easy ownership rather than unnecessary complexity.

• Long Shaft (~20") – Deeper skiffs and many sailboats

Measure from the keel to the top of the transom. If you’re between sizes, choosing the longer shaft usually helps maintain clean water pickup.
