Honda 50 HP Steering Electric Start Power Trim Long Shaft Outboard Motor

The Honda BF 50 DK4 LRTZ is a 4-stroke outboard marine engine designed for small and medium-sized fiberglass or aluminum boats, 3.5–6 meter inflatables, requiring a long shaft, with 50 HP / 36.8 kW and an 808 cc 3-cylinder OHC PGM-FI engine. The BF 50 DK4 LRTZ, with its 808 cc 3-cylinder OHC engine, offers a reliable and economical power source for small and medium-sized boat users.

BF 50 DK4 LRTZ Engine Technology and Key Advantages

PGM-FI electronic injection provides easy cold starting and consistent power output. Maintenance requirements are lower compared to carbureted alternatives. A 25-liter internal tank ensures comfort for medium-distance routes.

• 3-Cylinder OHC PGM-FI Engine (808 cc, 3 Cylinders): PGM-FI electronic injection provides easy cold starting and consistent power output
• Long Shaft (508 mm (20")): perfect fit for small and medium-sized fiberglass or aluminum boat transom heights — propeller operates at optimal depth
• F–N–R Gear System: Forward, neutral, and reverse — full control in tight spaces, dock, and marina maneuvers
• Electric Start: Instant activation with key or button — comfortable and quick starting
• Electric Trim and Tilt: Adjust trim angle with a button — fuel efficiency and speed optimization during navigation; ability to fully raise the engine with tilt
• 25 Liter Internal Tank: Sufficient capacity for medium-distance routes; option for external tank connection for longer voyages

Long Shaft — What Type of Boat Is It Suitable For?

The long shaft (508 mm (20")) is suitable for most 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

How fast can a boat go with a Honda 50 HP engine?

50 HP power varies depending on boat size and load. On a 4-meter inflatable boat with a medium load, a speed of approximately 25–35 knots is expected. Actual speed is directly related to boat type, propeller pitch, and load capacity.

What advantage does the PGM-FI system offer in this power class?

PGM-FI electronic injection offers easy cold starting and consistent power output. Maintenance requirements are lower compared to carburetors.

Is a 25-liter internal tank sufficient for daily use?

At 50 HP power at medium RPM, a consumption of approximately 9.0–11.0 L/hour is expected. With a 25 L tank, a cruising range of 3–5 hours is provided. For longer routes, an external tank connection is recommended.

Which boat and inflatable brands are compatible with the BF 50 DK4 LRTZ?

Honda outboard motors are compatible with the vast majority of Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and domestic brand inflatable boats 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 share your boat model to get compatibility confirmation from Clever Marin.
