Honda 30 HP Steering Electric Start Power Trim Long Shaft Outboard Motor

The Honda BF 30 DK2 LRTU is a 4-stroke outboard marine engine designed for small fiberglass, aluminum, or inflatable boats requiring a long shaft, measuring 2.5–4.5 meters, with 30 HP / 22.1 kW and a 552 cc 2-cylinder OHC Carbureted engine. The BF 30 DK2 LRTU, with its 552 cc 2-cylinder OHC engine, offers smoother power delivery and less vibration compared to single-cylinder alternatives.

BF 30 DK2 LRTU Engine Technology and Key Advantages

The 2-cylinder OHC structure reduces vibration with more frequent firing intervals and balances power output. With a portable weight of 79.5 KG, it provides a balanced power-to-weight ratio in this power class.

• 2-Cylinder OHC Carbureted Engine (552 cc, 3 Cylinders): The 2-cylinder OHC structure reduces vibration with more frequent firing intervals and balances power output.
• Long Shaft (508 mm (20")): Perfect fit for small fiberglass 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
• Electric Start: Instant engagement with a key or button — comfortable and fast starting
• Electric Trim and Tilt: Adjust trim angle with a button — fuel efficiency and speed optimization during navigation; possibility to fully raise the engine with tilt
• 25 Liter Internal Tank: Sufficient capacity for medium-range routes; option for external tank connection on long voyages

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.

Technical Specifications

Who Is This Engine For?

• Primary engine for 2.5–4.5 meter inflatable boats and small boats: 2-cylinder balanced power and low vibration
• Fishing and lake use: Quiet 4-stroke operation for smooth cruising without scaring fish
• Auxiliary engine for sailboats: Marina maneuvering and short passage power
• Backup engine: Portable option as an additional safety solution for large boats

Maintenance and Longevity

4-stroke Honda engines run trouble-free 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 each use.

Frequently Asked Questions

What boat size is the Honda 30 HP engine suitable for?

30 HP power is an optimized range for 2.5–4.5 meter inflatable boats and small aluminum boats. The most efficient performance is achieved on boats with a total weight between 200–400 kg.

How much better is a 2-cylinder OHC engine compared to single-cylinder alternatives?

Two cylinders produce less vibration and smoother power output due to more frequent firing intervals. This difference is especially noticeable at full throttle and against the wind. The 4-stroke structure, which does not require an oil-gasoline mixture, provides low maintenance costs.

How does the electric start system work?

Electric start instantly engages the engine with a turn of the key. Requires battery connection.

Which boat and brand models is the BF 30 DK2 LRTU 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 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.
