The first NEW big block engine in more than a decade – the 8.2L MAG EFI continues MerCruiser's tradition of delivering the industry's best reliability, performance and ease-of-ownership. Engineered in collaboration with Mercury Racing, the 8.2L MAG EFI provides the superior big block fuel efficiency and performance boaters are accustomed to. Rated by MerCruiser @ 380hp at the prop.

  • Engine protection from overheating, low oil pressure or low drive lube by MerCruiser's exclusive "Engine Guardian" protection system.


  • Sensational acceleration, immediate planning and superior mid-range throttle response delivered by the 8.2L V8 powerhouse.
  • Exciting performance and improved fuel efficiency – while protecting the environment – with MerCruiser's Emissions Control Technology.
  • Surplus power created by the 8.2L's large 65A high-output alternator.
  • Smooth operation and unsurpassed responsiveness with optional Digital Throttle & Shift system.


  • Easily check or add lubricant from inside the boat with the engine-mounted drive lube monitor
  • Draining water is a snap with MerCruiser's standard single-point air-actuated water drain system
  • Oil changes are cleaner, quicker and simpler via convenient top-mounted remote oil filter and threaded dipstick tube.
  • Checking fluid levels is simple and straightforward using color-coded service points
