The Powerful MerCruiser 500 HP Outboard Engine

For boaters looking for exhilarating speed and power on the open water, the MerCruiser 500 horsepower outboard engine delivers. As one of the most powerful sterndrive engines available from Mercury Marine, MerCruiser's 500 hp option offers next-level performance for offshore racing and pleasure boating alike.

Technology Behind the 500 HP Engine

At the heart of the MerCruiser 500 is Mercury Racing's 512 cubic inch displacement (CID) engine block. Built with durable cast iron, this naturally aspirated powerhouse utilizes overhead valve architecture and a healthy 10:1 compression ratio to generate tremendous horsepower.

The 500 hp MerCruiser relies on direct fuel injection, with four fuel injectors mounted in the cylinder heads. This allows for precise fuel metering to squeeze every ounce of performance from the engine. It also ensures reliable starting, even after long-term storage between uses.

Performance Capabilities

With 500 horses and 565 ft-lbs of raw torque on tap, the MerCruiser 500 offers incredible acceleration. Throttle response stays sharp even when already on plane thanks to the engine's high airflow design and Dynamic Charging System (DCS) alternator.

The DCS alternator maintains electrical charging output even at high rpm. This keeps voltage steady to engine sensors, fuel injectors, and ignition coils when you need power the most.

Durability and Maintenance

Mercury Racing engines are designed from the ground up for extreme use during offshore powerboat racing. So despite its high performance, the MerCruiser 500 hp engine offers incredible durability as well.

An ECU engine controller monitors operating conditions in real time. This enables adaptive fuel mapping to prevent detonation. The ECU can also regulate oil delivery based on factors like engine temperature, load, and rpm.

Customization Options

As a sterndrive package, the MerCruiser 500 gives boaters flexibility when it comes to transoms and propulsion. You can pair this engine with Mercury's range of Alpha and Bravo drives to match your boat's needs.

Further customization potential comes from Mercury's family of Enertia propellers. Dial in different pitch, diameter, and blade area options to optimize acceleration, top speed, and handling.

Unleashing 500 Horses on the Water

When powered by Mercury Racing's muscular 512 CID engine, the MerCruiser 500 hp sterndrive opens up a world of high velocity fun on the water. Offshore race teams rely on packages like this for winning performance. Now you can experience the same extreme power and acceleration for your family boat.
