BF 115 J XRU Engine Technology and Key Advantages

The DOHC (Dual Overhead Camshaft) design precisely controls valve movement with two camshafts. The 16-valve system prevents power loss at high RPMs. PGM-FI electronic injection ensures consistent power output and comfortable cold-weather starting.

• 4-Cylinder DOHC PGM-FI Engine (2354 cc, 4 Cylinders): The DOHC (Dual Overhead Camshaft) design precisely controls valve movement with two camshafts.
• Extra-Long Shaft (572 mm (22.5")): perfectly suited for medium-sized fiberglass transom heights — propeller operates at optimum depth.
• F–N–R Gear System: Forward, neutral, and reverse — full control in tight spaces, dock, and marina maneuvers.
• Electric Start: Instant activation with a key or button — comfortable and quick starting.
• Electric Trim and Tilt: Adjust trim angle with a button — optimizes fuel efficiency and speed during cruising; allows full engine tilt-up.
• External Fuel Tank: Range determined by user needs — comfort for long journeys with external tank connection.
• White Finish: Absorbs less solar heat compared to standard black alternatives; provides aesthetic compatibility.

Extra-Long Shaft — Which Boat Type 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 transoms. It is 64 mm longer than the standard long shaft (508 mm); measure your transom height before installation.

Frequently Asked Questions

Which boat size is the Honda 115 HP engine most suitable for?

115 HP power is optimized for medium-sized boats 5–7 meters in length. The 4-cylinder design offers significant advantages over single and two-cylinder alternatives for load carrying and open sea conditions.

What difference does the DOHC system make in this power class?

DOHC precisely maintains valve timing even at high RPMs thanks to two camshafts. The 16-valve structure increases combustion efficiency — more power with the same fuel.

What is the advantage of electric trim?

Electric trim allows you to adjust the engine angle with a button according to boat speed and load conditions. The correct trim angle can significantly reduce fuel consumption. The ability to make instant adjustments during cruising offers a major comfort difference compared to manual trim models.

Which boat and inflatable boat brands are compatible with the BF 115 J XRU?

Honda outboard engines are compatible with the vast majority of 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 572 mm (22.5") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
