Mercury 150 HP Racing Outboard Engine with Electric Start, Steering, Power Trim and Tilt, Extra Long Shaft

The Mercury Racing 150 XL is a 4-stroke outboard marine engine designed for high-speed performance boats, racing boats, and offshore sport boats that require an extra-long shaft, featuring 150 HP / 112 kW and a 3400 cc V6 (6 Cylinder) engine. The Racing series is Mercury's high-performance focused outboard engine group. With a naturally aspirated high-performance engine and Racing ECU calibration, maximum power and speed are targeted.

Racing 150 XL Series Features and Technology Advantages

High-performance ECU calibration extends the optimal powerband compared to standard FourStroke engines. Precise maneuver control at high speeds is ensured with AMS electro-hydraulic steering.

• V6 (6 Cylinder) Engine (3400 cc): High-performance ECU calibration extends the optimal powerband compared to standard FourStroke engines
• Extra Long Shaft (572 mm (22.5")): The propeller operates at the optimum depth with the correct transom height
• High Performance ECU: Extended powerband with Racing calibration
• Electric Start: Instant activation with key or button — comfortable and quick starting
• Power Trim & Tilt: Adjusting the trim angle with a button while cruising — fuel efficiency optimization; full motor lift with tilt
• Floating External Fuel System: Connection to a large-capacity external tank — range determined by user needs

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

The extra-long shaft (572 mm (22.5")) ensures the propeller operates in the correct water depth on large, high-sided fiberglass and aluminum boats. It is 64 mm longer than the standard long shaft (508 mm).

Frequently Asked Questions

Which boat type is the Mercury Racing 150 HP engine suitable for?

The Racing series is developed for speed-oriented performance boats with 150 HP. It provides maximum performance in offshore racing boats, catamarans, and high-speed sport boats. Weight optimization and power density are priorities for this segment.

How does a High-Performance Mercury Racing engine work?

The high-performance ECU uses different injection timing and ignition maps compared to standard FourStroke engines. The powerband is optimized for high RPMs.

How is the Racing series maintained?

Racing engines require a special maintenance protocol suitable for high-performance use. Beginning-of-season and end-of-season services should be performed at authorized Mercury service centers. Oil quality and change intervals may be more frequent than for standard FourStroke engines.

Which boat and brand models are compatible with the Racing 150 XL?

Mercury outboard motors are compatible with many fiberglass, aluminum, and inflatable boat models thanks to their universal transom clamp or transom mounting 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.
