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.

Mercury EFI outboards deliver reliable turnkey starts, improved fuel efficiency, and instant throttle response.
