Technical Details

Corrosion Defense

Constructed with Mercury's proprietary XK360 low-copper aluminium alloy and sealed with the MercFusion Paint Process. This system uses electro-deposition priming and a hard powder top coat to provide the industry’s best protection against saltwater intrusion.

Extreme Validation

Every engine design endures brutal testing protocols, including vicious log strikes, saltwater spray booths, high-humidity chambers, and thermal cycling between extreme hot and cold water temperatures. Powerheads are run at wide-open throttle for thousands of hours to prove long-term durability.

High-Displacement Power:

Mercury engines utilise large-displacement blocks to generate torque effortlessly. This "work smarter, not harder" approach ensures the engine is never stressed, even when pushing heavy loads.

SmartCraft Integration:

Engines are compatible with the SmartCraft digital suite. This provides access to Engine Guardian (which monitors sensors to protect the engine) and Active Trim (GPS-based automatic trim control) for optimized performance and fuel economy.
