Honda 4-Stroke Engines: Models, Specs and Maintenance

Honda Marine Unveils New BF4 and BF6 Kickers and Redesigned BF5 Outboard

Honda Marine has introduced its latest compact outboard family: the BF4 and BF6 kickers, along with a redesigned BF5 model. All three are powered by the same 127cc single-cylinder 4-stroke engine and are offered in both short-shaft (15-inch) and long-shaft (20-inch) configurations to suit a variety of small-boat applications.

Design and Practical Features

These compact outboards are engineered for simplicity, reliability, and low vibration. A new decompression mechanism helps make starting easier, reducing the effort required on manual pulls. For quick shutdowns, Honda includes a one-push stop switch that immediately cuts power when needed. Rubber engine mounts are used to isolate vibration, which diminishes perceived engine noise and improves comfort for operators and passengers on small craft.

Fuel and Electrical Options

Honda integrates a 1.5-liter fuel tank into the outboard, providing a convenient on-board fuel source for short trips, trolling, or as a kicker motor. For users who need to power or charge electronics while underway, Honda offers an optional charging system designed to supply power to small electronic devices. This optional feature can be useful for charging phones, portable fishfinders, or other accessories when the engine is running.

Mounting and Shaft Length Choices

Offering both 15-inch (short-shaft) and 20-inch (long-shaft) options makes these engines versatile for different transom heights and boat designs. Short-shaft models work well on small skiffs, dinghies, and tenders with lower transom heights, while the long-shaft versions accommodate higher transoms and provide better clearance in slightly larger small boats. Choosing the correct shaft length helps ensure proper prop immersion and optimal handling.

Who These Outboards Are For

These compact 127cc 4-stroke outboards are aimed at boaters who need a lightweight, dependable kicker or primary propulsion for small vessels. They are suitable for tender duty, beaching, fishing from small craft, or as auxiliary motors to larger primary engines. The combination of easy starting, reduced vibration, and an integrated fuel tank makes them practical for users who value simplicity and low maintenance.

Price and Availability

Honda lists the new models in a price range of $1,875 to $2,150, depending on configuration and options. For more information, Honda Marine offers regional support through its Alpharetta, Georgia office.
