BF 350A 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 the transom height of large fiberglass or aluminum boats — propeller operates at optimal depth.
• F–N–R Gear System: Forward, neutral, and reverse — full control in narrow 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 — optimizes fuel efficiency and speed during navigation; ability to fully raise the engine with tilt.
• External Fuel Tank: Range determined by user needs — comfort for long journeys with an external tank connection.
• White Coating: 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 fiberglass and aluminum boats with high freeboards. It is 64 mm longer than the standard long shaft (508 mm); measure your transom height before installation.

Frequently Asked Questions

What boat size is the Honda 350 HP engine suitable for?

The 350 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 has longer maintenance intervals.

What do 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 — essential for entering shallow waters, docking, and storage.

Which boat and brand types is the BF 350A XDU compatible with?

Honda outboard motors are compatible with most 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 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.
