The Mercury Racing 500 XL is a 4-stroke outboard marine engine designed for high-speed performance boats, race boats, and offshore sport boats requiring an extra-long shaft. It features a 500 HP / 372 kW, 4600 cc V8 (8 Cylinder) engine. The Racing series is Mercury's high-performance focused outboard engine line. Maximum power and speed are targeted with a supercharged V8 engine block and Racing ECU calibration.
The supercharged design provides significantly higher power output at the same displacement compared to naturally aspirated alternatives. The charge-air cooling system increases combustion efficiency by cooling the supercharged air. Precise maneuver control at high speeds is ensured with AMS electro-hydraulic steering.
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 the standard long shaft (508 mm).

4-stroke Mercury engines operate trouble-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. In saltwater use, freshwater flushing is mandatory after every use.

The Racing series is developed for speed-focused performance boats with 500 HP. It provides maximum performance in offshore race boats, catamarans, and high-speed sport boats. Weight optimization and power density are priorities for this segment.
A supercharged system provides a higher air-fuel mixture to the engine than standard atmospheric pressure. The charge-air cooling system cools the supercharged air, minimizing the risk of detonation and maintaining continuous maximum boost pressure.
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 standard FourStroke engines.
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.
Share your boat model, transom height, and intended use — let's confirm the suitability of the Mercury Racing 500 XL engine for your boat and the correct shaft selection together.
The electronic fuel injection system ensures flawless starting at any temperature and stable power output at all RPMs. Because it optimizes fuel consumption down to the millimeter, it both enhances performance and offers significant savings on long journeys. This allows users of all types, from small boats to professional fleets, to achieve greater range with less fuel.
Quiet and vibration-reduced operation.
Mercury's unique engine block design naturally absorbs vibrations and minimizes noise. This creates a comfortable environment for both driver and passengers during extended voyages. Whether for fishing, cruising, or professional use, the low noise level ensures a pleasant and stress-free experience on the water.
Durable, corrosion-resistant housing.
Special alloys and multi-layer protection are used against saltwater, humidity, and harsh environmental conditions. This structure not only extends the engine's lifespan but also reduces the need for maintenance. For users who want an engine that can operate with high performance for years, Mercury becomes one of the most reliable brands in terms of durability.
