Engine - Mercruiser NEW, 350 Mag, MPI, ECT, Alpha

A new Mercruiser 350 Mag fuel injected bobtail engine equipped with catalyst system to be used with an Alpha sterndrive.

RELIABILITY

  • ECM 555 fuel and ignition system along with platinum-tipped spark plugs ensure reliable starts and outstanding performance, year after year
  • Exclusive Engine Guardian protection senses potential problems and virtually eliminates the chance for engine damage due to overheating, low oil pressure, or low drive lube
  • Dry-joint exhaust eliminates the chance for water to enter engine through leaky gaskets
  • Water-separating fuel filter helps protect fuel system and engine against damage
  • Proven GM cast iron block V8 power for years of reliable operation
  • EDP-coated exhaust elbows better resist high temperature and corrosion
  • Brass sea water pump housing improves life and better resists damage from running dry

PERFORMANCE

  • Multi-Port Fuel Injection provides easy starts, cold or hot, and automatically adjusts for changes in temperature, weather, or altitude for terrific performance in any environment
  • Two-piece, long-runner intake manifold design improves low and mid-range torque for better acceleration and handling heavy loads
  • HVS Ignition with knock control maximizes power and protects against low quality fuels
  • Standard anti-feedback power steering helps reduces operator fatigue and makes boat handling a breeze
  • Low restriction flame arrestor for added horsepower and torque

EASY OWNERSHIP

  • 3-year/300 hour maintenance interval on many periodic service items saves time and money
  • Convenient top-mounted remote oil filter and threaded dipstick tube make oil changes cleaner and keep periodic servicing quick and simple
  • Color-coded service points makes checking fluid levels simple and straightforward
  • Operates on easy to find, less expensive 87 octane fuel
  • Engine-mounted drive lube monitor for easy lube check or add from inside the boat
  • All models come with simple to use water drain systems designed for many boat applications

TECHNOLOGY

  • The DTS (Digital Throttle & Shift) option eliminates push-pull cables and related maintenance while providing silky-smooth operation and unsurpassed responsiveness. DTS provides an unprecedented level of control and precision for docking and low-speed maneuvering. Available as an additional option, precision SmartTow speed control includes an easy-to-use launch control that makes pulling skiers and wakeboarders as simple as pushing a button
  • Standard features with DTS are: Autosynch of multiple engines, SmartStart, Shift Protection, Multiple Helm capability, and Shadow Technology for triple and quad engine installations
  • MerCathode galvanic corrosion prevention system standard on Bravo models, available on Alpha models, offers unmatched active electronic corrosion protection
  • MPI engines are designed to display engine information on your choice of analog or SmartCraft digitally-driven gages and displays.
