Honda 6 HP Rope Start Long Shaft Outboard Motor

The Honda BF 6 DH LHNU is a 4-stroke outboard marine engine designed for inflatable boats, small fiberglass or wooden boats, and 2-3.5 meter boats that require a long shaft, featuring a 6 HP / 4.4 kW and 127 cc 1-cylinder OHV water-cooled carbureted engine. With its 127 cc OHV engine, the BF 6 DH LHNU offers reliable 4-stroke power to small boat and inflatable boat users with its simple and proven mechanical structure.

BF 6 DH LHNU Engine Technology and Key Advantages

The OHV (Overhead Valve) design ensures efficient combustion by positioning the valves in the cylinder head. With a weight of 27.5 KG, single-person transport and transom mounting are possible. The 1.5 L internal tank eliminates the need for an external fuel tank for daily use.

• 1-Cylinder OHV Water-Cooled Carbureted Engine (127 cc, 1 Cylinder): The OHV (Overhead Valve) design ensures efficient combustion by positioning the valves in the cylinder head.
• Long Shaft (508 mm (20")): Perfect fit for inflatable boat transom height — propeller operates at optimum depth.
• F–N–R Gear System: Forward, neutral, and reverse — full control in narrow spaces, dock, and marina maneuvers.
• Manual Rope Start: Battery and electricity independent — mechanical reliability ready to start in all conditions.
• Manual Trim: Manual adjustment of transom angle — simple and reliable mechanical structure, electricity-independent operation.
• 1.5 Liter (internal) Integrated Tank: No external tank required — ready for daily short-distance use, easy to carry.

Long Shaft — What Type of Boat is it Suitable For?

The long shaft (508 mm (20")) is suitable for the vast majority of inflatable boats, aluminum fishing boats, and small fiberglass boat models. For boats with a transom height of 381 mm, a short shaft model should be preferred.

Frequently Asked Questions

Does the Honda BF 6 DH series have F-N-R gears?

Yes, the Honda BF 6 DH series comes standard with an F–N–R (Forward / Neutral / Reverse) gearbox. It offers a significant control advantage in narrow dock maneuvers and docking compared to gearless alternatives.

What speed can be achieved in an inflatable boat with 6 HP power?

With a 6 HP engine in a 2.5–3 meter inflatable boat, a speed of approximately 8–14 knots is expected. Boat weight, number of occupants, and wind conditions directly affect the speed. In economical use, fuel consumption is below 1 liter per hour.

Is the 1.5-liter internal tank sufficient?

It is sufficient for short-distance and daily use. It offers approximately 1 hour of autonomy at full power. At half throttle, it generally suffices for daily fishing trips. For long routes, an external tank connection is recommended.

Which boat and brand types is the BF 6 DH LHNU compatible with?

Honda outboard engines are compatible with the vast majority of inflatable boats from brands like Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and local brands, thanks to their universal transom clamp system. The only criteria are your boat's transom height of 508 mm (20") and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
