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 are the advantages of the PGM-FI injection system 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 350A XDU?

Honda outboard engines are compatible with most 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 572 mm (22.5") and the maximum engine power approved by the manufacturer. You can confirm compatibility with Clever Marin by sharing your boat model.
