Four Stroke 40-60 HP

There are plenty of good reasons these Mercury 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.
With a balanced powerhead and sophisticated cowl design, Mercury FourStroke outboards deliver an exceptionally smooth and quiet ride at any speed.
Explore farther and stay out longer thanks to an impressive power-to weight ratio and optimized fuel injection that maximize performance from every drop of fuel.
With features ranging from a no-spill oil change system and easy-access fuel filter, to a valve train that remains maintenance-free for the life of your engine, Mercury FourStroke outboards are easy to maintain for lasting peak performance.

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.
