Up to 3 mph faster than its nearest competitor and more than 1 mph faster than Mercury’s standard 115 FourStroke, the 115 Pro XS FourStroke’s higher rpm range delivers improved performance out of an already-powerful engine.
When you're feeding your need for speed, Mercury Pro XS engines will get you there faster. Engineered to meet the demands for high speeds on fresh or salt water, these high-performance motors deliver a winning combination of power, acceleration, durability, and fuel efficiency.
Mercury Racing applies its supercharging expertise to extract incredible power and torque from the 4.6-liter V8. A 2.4-liter belt-driven twin-screw supercharger delivers pressurized ambient air to the intake tract with no lag for instant throttle response. The supercharger is water-cooled to reduce the temperature of the intake charge and increase power and torque.
