Description

FourStroke – Excellence without compromise



Elevate your experience on the water with Mercury FourStroke outboards. Designed to deliver unsurpassed power and performance in an efficient, reliable package that’s built to please, the new FourStroke V8 and V6 outboards are the smallest and lightest in their class. They’re engineered to go the distance on a wide variety of boats, and to make every adventure all it should be.

Features
  • Engine Details: Quick-revving double-overhead camshaft design and deep-breathing intake deliver thrilling and satisfying performance. Great for aluminum console, deck, inflatable rigid hull, inshore fishing, offshore fishing, and runabout boats and tritoons.
  • Available with Joystick Piloting: Joystick piloting is available on V6 3.4L 200hp and 225hp FourStroke outboards with Digital Throttle & Shift (DTS). In addition to easy joystick docking and maneuvering, the system allows you to hold a boat in position, hold its heading, or even hold its position and heading simultaneously.
  • Adaptive Speed Control: Adaptive Speed Control allows boaters to maintain engine speed (rpm) regardless of load or condition changes - such as rough water, tight turns, tow sport activities and lower speeds on plane - without having to frequently adjust throttle position.
  • Discover better boating: Active Trim by Mercury makes boating easier and more enjoyable by automatically trimming your engine. Active Trim simplifies boat operation while improving engine performance and decreasing fuel costs.
