Gas Sterndrive 320 hp - MX 6.2 MPI

Boating Benefits

Designed and built exclusively by MerCruiser® and available only from MerCruiser, the MX 6.2 MPI actually weighs less than the 7.4L it replaces — yet delivers significantly greater horsepower. It’s the perfect choice for midsize runabouts, performance boats, fishing boats, and cruisers. It sports a host of impressive features.

  • The MEFI 3 Electronic Control Module with multiport fuel injection, which provides precise fuel and spark control for unmatched top-end throttle response, easy starts and excellent day-to-day operation.
  • Exclusive quick oil drain system that eliminates the need for a pump, simplifying routine maintenance.
  • Ceramic- and EDP-coated exhaust elbows for outstanding corrosion resistance.
  • Water-cooled and insulated fuel system that keeps fuel temperatures at optimum levels while reducing the potential for vapor lock.
  • Billet steel special profile camshaft with low-friction roller followers for quiet, efficient, durable operation.
  • Cast-iron block, forged-steel crankshaft, and high-strength aluminum-alloy pistons to ensure durability and reliability.
  • 70-amp alternator to handle the demands of today’s state-of-the-art electronic components.
  • Water-separating fuel filter that prevents water from entering the fuel system.
  • Exclusive remote oil filter located atop the engine, simplifying routine maintenance.
  • Exclusive drive lube monitor conveniently located atop the engine for easy access.
  • Exclusive Mercury MerCruiser® service dealer network.
