4.6L V8 Supercharged 500R
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.
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.
Advanced Racing Core (Arc) Midsection
The new Advanced Racing Core (ARC) midsection is engineered to upgrade durability and performance.
Mercury Racing has engineered the Advanced Racing Core (ARC) midsection to compliment the extreme thrust and high-speed capability of the 500R outboard. This is the strongest, stiffest and most-durable midsection ever created by Mercury Racing, and it is exclusive to the 500R outboard.
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.
The Shape of Speed
A crescent leading edge and long aspect 5.9-inch torpedo are hydrodynamically tuned for high speeds in any application. Equipped with 1.60:1 gear ratio and designed to turn propellers up to 17 inches in diameter.
A new intermediate spray plate reduces drag in submerged and transition applications.
Low water pickups plus a new adjustable nose cap inlet system optimize water flow for submerged, transition and high-speed surfacing applications.
To support a generous flow of cooling water to the powerhead water pump capacity is increased by 57 percent.
A rugged new 1-inch diameter driveshaft and 1.5-inch diameter propshaft are designed to handle the torque and thrust of 500 horsepower.
The R-Drive gearcase features a standard skeg length with a very efficient parabolic cross-section shape with left- or right-hand camber to balance steering force with standard and counter rotation props. Designed to perform in submerged and transition applications on boats capable of speeds between 85 and 100mph.
The R-Drive Sport is optimized for surfacing applications at speeds beyond 100 mph. Its longer skeg maintains steering control while operating fully surfaced at the high mounting positions desirable for many of the fastest hulls.

Digital Throttle & Shift (DTS)
The precision of Digital Throttle and Shift (DTS) with available Mercury Racing Digital Zero Effort controls eliminates cable maintenance and delivers smooth shifting with instant throttle response.
Adaptive Speed Control
Adaptive Speed Control maintains engine RPM as load changes due to sea conditions or turning maneuvers to maintain boat authority with less control input.
The 500R model supports the full suite of Mercury SmartCraft technologies, including the Engine Guardian monitor system. Stream engine and performance data to a Mercury VesselView multi-function display or to many other multi-function displays.
