The Honda BF 150D LDU is a 4-stroke outboard marine engine designed for mid-sized fiberglass, aluminum, or inflatable boats, 5–7 meters in length, that require a long shaft, featuring a 150 HP / 110 kW and 2354 cc 4-cylinder DOHC PGM-FI engine. With its 2354 cc 4-cylinder DOHC engine, the BF 150D LDU offers a quiet, efficient, and reliable power source for mid-sized boat users.
BF 150D LDU 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-Cylinder): The DOHC (Dual Overhead Camshaft) structure precisely controls valve movement with two camshafts.
-
Long Shaft (508 mm (20")): perfect fit for mid-sized fiberglass transom height — propeller operates at optimum depth
-
F–N–R Gear System: Forward, neutral, and reverse — full control in tight spaces, at the dock, and during marina maneuvers
-
Electric Start: Instant activation with key or button — comfortable and quick starting
-
Electric Trim and Tilt: Adjust trim angle with a button — fuel efficiency and speed optimization during cruising; possibility to fully raise the engine with tilt
-
External Fuel Tank: Range determined by user needs — comfort for long journeys with external tank connection
-
White Coating: Absorbs less solar heat compared to standard black alternatives; provides aesthetic harmony.
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.

Maintenance and Longevity
4-stroke Honda engines run problem-free for many years with regular oil changes and end-of-season maintenance protocols. The impeller of the water-cooled system should be checked every 100 hours or every two seasons. Fresh water rinsing is mandatory after every use in saltwater.

Frequently Asked Questions
Which boat size is the Honda 150 HP engine best suited for?
150 HP power is optimized for mid-sized boats between 5–7 meters in length. The 4-cylinder structure offers significant advantages over single and twin-cylinder alternatives in terms of load carrying and open sea conditions.
What difference does the DOHC system make in this power class?
Thanks to its two camshafts, the DOHC system 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 manual trim models.
Which boat and inflatable boat brands are compatible with the BF 150D LDU?
Honda outboard motors 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 508 mm (20") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
