The Honda BF 300A XDU is a 4-stroke outboard marine engine designed for large fiberglass or aluminum boats, yachts, and professional commercial vessels requiring an extra-long shaft, featuring a 300 HP / 223.7 kW and 4952 cc V8 SOHC VTEC PGM-FI engine. The BF 300A XDU with its 4952 cc V8 SOHC VTEC engine is optimized for large boats, dual-engine configurations, and professional marine applications.
The V8 VTEC system prevents power loss at high RPMs, while PGM-FI electronic injection precisely controls fuel dosage. The 32-valve SOHC structure combines a wide power band with low fuel consumption.
The extra-long shaft (572 mm (22.5")) ensures the propeller operates at the correct water depth on large, high-sided fiberglass and aluminum boats. It is 64 mm longer than a standard long shaft (508 mm); measure your transom height before installation.

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. Fresh water rinsing is mandatory after each use in saltwater.

The 300 HP V8 power is generally suitable for large fiberglass or aluminum boats 8 meters and above. In a dual-engine configuration, the total power doubles. Always check your boat's maximum engine power plate.
PGM-FI electronic injection provides easy starting in cold weather, consistent power output, and low fuel consumption. Compared to carbureted alternatives, it does not require choke adjustment, and maintenance intervals are longer.
Electric trim adjusts the boat's angle in the water with a button, optimizing fuel efficiency and cruising comfort. Tilt is used to fully raise the engine — necessary for entering shallow waters, docking, and storage.
Honda outboard motors are compatible with most Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and local brand inflatable boats due to their universal transom clamp system. The only criteria are your boat's transom height of 572 mm (22.5") and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
Share your boat model, transom height, and intended use — let's confirm together the suitability of the Honda BF 300A XDU engine for your boat and the correct shaft selection.
Honda's BLAST (Boosted Low Speed Torque) system optimizes ignition timing at low revs, generating extra torque during takeoff and acceleration. This allows for faster recovery, especially when maneuvering under load. This results in a safe and controlled ride in both fishing boats and long-hulled fiberglass vessels.
With Lean Burn Control
Intelligent Fuel Management
Lean Burn Control measures the engine's required combustion mixture in real time at cruising speed, applying a more refined combustion profile. This significantly reduces fuel consumption on long journeys, while also keeping the engine cooler and more stable. It offers a noticeable advantage in terms of range, especially for summer boaters and commercial vessels.
Multilayer Honda
Corrosion Protection
Honda Marine hulls are protected by a multi-layer electroplating system developed to withstand saltwater and humid environments. The aluminum alloy block, zinc anodes, and special surface coatings work together to delay corrosion for years. Even in boats that spend a lot of time at sea, the engine's exterior and internal components remain durable, extending maintenance intervals.
