Description

Rethink the V-8.



A 6.2-liter V-8 engine with unparalleled torque and acceleration to get you on plane quickly and smoothly.

Key Features
  • Rethink the V-8.: We certainly did. Everything, part by part, system by system, with a total design and engineering commitment to marine use. The result? A 6.2-liter V-8 engine with unparalleled torque and acceleration to get you on plane quickly and smoothly. A whole new sporty feel at the wheel. Significant reductions in sound and vibration at the helm. Major improvements in the cockpit environment, by design. All wrapped in the legendary reliability you’ve come to expect from Mercury.®
  • Powerful Performer.: Power and acceleration is delivered with 6.2 liters of displacement and a long-runner scroll intake manifold that optimizes air flow for higher torque.
  • Repower Financing: With Mercury Repower Financing, you can easily power up everything from fishing boats, to runabouts, to cruisers with flexible financing on the engine. You can also choose to finance rigging, gauges, controls and even labor. Mercury Repower Financing offers low rates and low monthly payments to fit a boater’s budget.
  • Sporty Handling.: Adaptive Speed Control maintains rpm during hard turns, creating a sportier, more intuitive driving experience without needless throttle adjustments.
  • Quiet Ride.: An unmatched boating experience thanks to an intake resonator and aft-facing throttle body that work together to dramatically reduce noise, while directing the engine sound away from the cockpit.
  • Smooth Operator.: Front and rear engine mounts isolate vibration for a smooth, quiet performance.
  • Easy To Maintain.: Accessible, easy-to-reach, color-coded maintenance points.
