BF 115 J LRU 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): DOHC (Dual Overhead Camshaft) structure precisely controls valve movement with two camshafts
• Long Shaft (508 mm (20")): 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, at docks, and during marina maneuvers
• Electric Start: Instant activation with key or button — comfortable and fast starting
• Electric Trim and Tilt: Adjust trim angle with a button — optimizes fuel efficiency and speed during cruising; possibility to fully raise the engine with tilt

Long Shaft — Which Boat Type Is It Suitable For?

The long shaft (508 mm (20")) is suitable for the vast majority of inflatable boats, aluminum fishing boats, and small fiberglass boat models. For boats with a transom height of 381 mm, a short shaft model should be preferred.

Frequently Asked Questions

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

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

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

Thanks to its two camshafts, DOHC maintains precise valve timing even at high RPMs. 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. The correct trim angle can significantly reduce fuel consumption. The ability to make instantaneous adjustments during cruising offers a major comfort difference compared to a manual trim model.

Which boat and inflatable boat brands is the BF 115 J LRU compatible with?

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 508 mm (20") transom height and the maximum engine power approved by the manufacturer. You can confirm compatibility with Clever Marin by sharing your boat model.
