BF 300A XDU Engine Technology and Key Advantages

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.

• V8 SOHC VTEC PGM-FI Engine (4952 cc, 8 Cylinders): The V8 VTEC system prevents power loss at high RPMs, while PGM-FI electronic injection precisely controls fuel dosage.
• Extra Long Shaft (572 mm (22.5")): Perfect fit for large fiberglass or aluminum boat transom heights — propeller operates at optimal depth.
• F–N–R Gear System: Forward, neutral, and reverse — full control in confined spaces, docking, and marina maneuvers.
• Electric Start: Instant activation with a key or button — comfortable and fast starting.
• Electric Trim and Tilt: Adjust trim angle with a button — optimizes fuel efficiency and speed during navigation; tilt allows the engine to be fully raised.
• External Fuel Tank: Range determined by user needs — comfort for long routes with an external tank connection.
• White Finish: Absorbs less solar heat compared to standard black alternatives; provides aesthetic harmony.

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

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.

Frequently Asked Questions

What boat size is the Honda 300 HP engine suitable for?

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.

What advantage does the PGM-FI injection system offer over a carburetor?

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.

What does electric trim and tilt do?

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.

Which boat and inflatable boat brands are compatible with the BF 300A XDU?

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.
