Honda 6 HP Rope Start Short Shaft Outboard Motor

The Honda BF 6 DH SHNU is a 4-stroke outboard marine engine designed for inflatable boats, small fiberglass or wooden boats, and 2-3.5 meter boats requiring a short shaft, featuring a 6 HP / 4.4 kW, 127 cc 1-Cylinder OHV Water-Cooled Carbureted engine. The BF 6 DH SHNU, with its 127 cc OHV engine, offers reliable 4-stroke power to small boat and inflatable boat users with its simple and proven mechanical structure.

BF 6 DH SHNU Engine Technology and Key Advantages

The OHV (Overhead Valve) design positions the valves in the cylinder head, ensuring efficient combustion. Its 27 KG weight allows for single-person carrying and transom mounting. The 1.5 L internal tank eliminates the need for an external tank in daily use.

• 1-Cylinder OHV Water-Cooled Carbureted Engine (127 cc, 1 Cylinder): OHV (Overhead Valve) design positions the valves in the cylinder head, ensuring efficient combustion.
• Short Shaft (381 mm (15")): Perfect fit for inflatable boat transom height — propeller operates at optimum depth.
• F–N–R Gear System: Forward, neutral, and reverse — full control in tight spaces, dock, and marina maneuvers.
• Manual Pull 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 transport.

Short Shaft — What Boat Type Is It Suitable For?

The short shaft (381 mm (15")) is suitable for the vast majority of standard inflatable boat, small fiberglass, and aluminum boat transom heights. It should not be confused with the long shaft model — the wrong choice will place the propeller at the wrong depth.

Maintenance and Longevity

Honda 4-stroke engines operate flawlessly for many years with regular oil changes and end-of-season maintenance protocols. The impeller of the water-cooled system should be checked every 100 hours or every two seasons. In saltwater use, freshwater flushing is mandatory after every use.

Frequently Asked Questions

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

Yes, the Honda BF 6 DH series comes standard with an F–N–R (Forward / Neutral / Reverse) gearbox. Compared to gearless alternatives, it provides a significant control advantage in tight dock maneuvers and berthing.

How fast can an inflatable boat go with 6 HP power?

With a 6 HP engine on a 2.5–3 meter inflatable boat, a speed of approximately 8–14 knots is expected. Boat weight, number of people, and wind conditions directly affect speed. In economic 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 throttle. At half throttle, it generally suffices for daily fishing trips. For long routes, an external tank connection is recommended.

Which boat and inflatable boat brands is the BF 6 DH SHNU compatible with?

Honda outboard motors are compatible with the vast majority of Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and local brand inflatable boats thanks to their universal transom clamp system. The only criteria are your boat's 381 mm (15") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
