Mercury 40 HP Tiller Outboard Motor – 2024

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. Great for aluminum tiller, aluminum console, inflatable rigid hull (RIB) and soft hull, watersports, and fish & ski boats.
