Standard Features
  • Durable.
    This high-displacement engine has a cast-iron block for rugged longevity. Mercury's exclusive Engine Guardian system senses any potential problems and instantly takes action to prevent engine or drive damages from low oil pressure, low drive lubricant or overheating.
  • Easy to maintain.
    Color-coded service points help you locate and check fluids faster. Easy access is ensured by the front-mounted dipstick and oil fill, not to mention a spin-on oil filter. Mercury's SmartCraft® system communicates all critical engine functions to the helm, putting you in complete control.
  • Fuel-Efficient.
    Sequential multi-port fuel injection precisely meters the air-to-fuel ratio, ensuring efficient operation any time the engine is running. The Emissions Control Technology (ECT) system works in tandem with the CPU to keep emissions in check. The result is better gas mileage and longer range.
  • Reliable.
    The 3.0L is known for quick, easy starting - regardless of air temperature - as well as smooth idling and excellent throttle response. The high-output alternator, which produces 65 amps at maximum rpm and 38 amps at idle, provides battery charging on demand.
  • 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.
