BF 115 J XRU Engine Technology and Key Advantages

The DOHC (Dual Overhead Camshaft) structure 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) structure precisely controls valve movement with two camshafts
• Extra Long Shaft (572 mm (22.5")): perfect fit for medium-sized fiberglass transoms — 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 engagement with a key or button — comfortable and fast starting
• Electric Trim and Tilt: Adjust trim angle with a button — fuel efficiency and speed optimization during cruising; possibility to lift the engine completely up with tilt
• External Fuel Tank: Range determined by user needs — comfort for long routes with external tank connection

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

The extra-long shaft (572 mm (22.5")) allows the propeller to operate at the correct water depth on large fiberglass and aluminum boats with high freeboards. It is 64 mm longer than a 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 structure offers significant advantages over single and twin-cylinder alternatives for carrying loads and in open sea conditions.

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

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

What are the advantages of electric trim?

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

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

Honda outboard motors are compatible with the vast majority of 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 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.
