Mercury Racing has introduced the Mercury Racing V8 500R outboard, which the company says it created “for no-compromise owners of the fastest luxury sport boats.”

Stuart Halley, Mercury Racing general manager, stated in a press release: “Capable of delivering more than 500 horsepower in a wide range of conditions and weighing as little as 720 pounds, the 500R establishes a new benchmark for outboard power density. This motor offers incredible mid-range punch and pulls with unrelenting authority all the way to wide-open throttle. This is the most exciting production outboard to ever emerge from the Mercury Racing shop.”

The 500R has more than 500 eager horsepower, which is 50 more horsepower plus 10 percent higher torque than the 450R model. Its 4.6-liter, 64-degree, V8 FourStroke powerhead is boosted by a Mercury Racing supercharger. The engine is designed to perform on pump fuel with a minimum 89-octane (95 RON) rating.

Also on the 500R are upgraded component designs in the powerhead, cooling system, midsection and steering system. A new, 5.9-inch diameter gearcase, available in R-Drive and R-Drive Sport configurations, transfers the power to the water.

What lengths are available for the Mercury Racing 500R? It can be ordered at 20 inches, 25 inches, 30 inches or 35 inches for single- or multi-engine applications.
