Overview

Description

Held to a Higher Standard.



There are plenty of good reasons these outboards rule the water. Start with no-worry reliability. More low-end torque for excellent acceleration. Increased fuel economy and outstanding overall performance. Enhanced fuel injection (EFI models) for boosted efficiency. A robust electrical system with a high-output alternator to keep batteries charged and fishing electronics humming. They have everything you need, and nothing you don't.

Features
  • A high-output alternator keeps batteries charged and fishing electronics humming. Great for aluminum tiller, aluminum console, jon, utility, and fish & ski boats.
  • Always Ready. All Season: Start it up and go. Anytime. That's the whole idea with a Mercury® FourStroke. Because it’s as close as you can get to maintenance-free. Tougher components, reliable electronic fuel injection (on select models), available SmartCraft® digital monitoring. More quality time in engineering means more quality time on the water.
