Honda 150 HP Electronic Steering Extra Long Shaft Outboard Motor

The Honda BF 150D XDU is a 4-stroke outboard marine engine designed for medium-sized fiberglass, aluminum, or inflatable boats, 5–7 meters in length, that require an extra-long shaft. It features a 150 HP / 110 kW, 2354 cc, 4-cylinder DOHC PGM-FI engine. The BF 150D XDU with its 2354 cc 4-cylinder DOHC engine offers a quiet, efficient, and reliable power source for medium-sized boat users.

BF 150D XDU 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 fuel injection provides 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
• Extra Long Shaft (572 mm (22.5")): perfectly suited for medium-sized fiberglass transoms — propeller operates at optimum depth
• F–N–R Gear System: Forward, neutral, and reverse — full control in tight spaces, docks, and marina maneuvers
• Electric Start: Instant activation with key or button — comfortable and quick 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
• 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 high-sided large fiberglass and aluminum boats. It is 64 mm longer than the standard long shaft (508 mm); measure your transom height before mounting.

Frequently Asked Questions

Which boat size is the Honda 150 HP engine most suitable for?

150 HP power is optimized for medium-sized boats ranging from 5–7 meters in length. The 4-cylinder structure offers a significant advantage over single and twin-cylinder alternatives in terms of load capacity and 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 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 150D XDU?

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.
