FOND DU LAC, Wis. (June 14, 2023) – Mercury Racing elevates outboard engine power and technology with the introduction of the Mercury Racing V8 500R model. This supercharged 500hp V8 outboard was created for no-compromise owners of the fastest luxury sport boats. The 500R introduces a host of new components engineered to complement the raw power produced by this engine and the challenging demands of extreme-performance boating. “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,” said Stuart Halley, Mercury Racing general manager. “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 delivers more than 500 eager horsepower, 50 more horsepower plus 10 percent higher torque than the 450R model. Its 4.6-liter 64-degree V8 FourStroke powerhead is boosted by an exclusive Mercury Racing supercharger. The engine is designed to perform on pump fuel with a minimum 89-octane (95 RON) rating. To handle this new level of power and to satisfy the most demanding performance boat owners, the 500R features upgraded component designs in the powerhead, cooling system, midsection and steering system. An all-new, 5.9″ diameter gearcase, available in R-Drive and R-Drive Sport configurations, efficiently transfers the power to the water while delivering outstanding durability, handling characteristics, and cooling. The 500R is available in four lengths – 20″, 25″, 30″ and 35″ – to accommodate any single or multi-engine performance application. The 26-inch center-to-center mounting distance on multi-engine transoms enables seamless installations on new boats and repower applications.
