STOUT POWERHEAD
Built from the inside out for rugged performance. Our new 4.6L V8 powerhead features upgraded components support to a scaled-up power output and deliver reliability you can count on.

BIGGER BOOST
Our power prescription calls for a 26% increase in supercharger boost pressure. Air flow is optimized with a larger intake attenuator and a new 92mm throttle body.

HUMIDITY COMPENSATION TECHNOLOGY
More power in every environment. For the first time in any marine engine, a new sensor measures the humidity level of the intake airflow to maintain the most aggressive calibration and optimize performance under virtually all conditions.

TRIMMED TO PERFECTION
Precise drive trim control is critical to realizing the high-speed potential of any performance boat. Mercury Racing leverages decades of experience in the heat of competition to engineer an upgraded trim and steering system for the 500R outboard that delivers unmatched precision.
