2026 Mercury Marine Fourstroke 40hp EFI 4 Cylinder

FourStroke 40-60 hp
It’s simple. You have places to go, and the Mercury 40 to 60hp FourStroke family of outboards is the easiest way to get there. Electronic fuel injection for reliable starts and increased efficiency. Smooth performance. Impressive torque. Rugged durability. It’s everything you need to get more out of your time on the water.

FourStroke Performance
Powerful Torque
A high-displacement powerhead generates serious low-end torque to easily power boats on plane. More torque requires less work from the engine, for a longer service life.

Quick Acceleration
The single-overhead-cam design delivers sporty acceleration and exciting overall performance from midrange through top speed. 

Hard-Working Muscle
With an available Command Thrust gearcase and ample torque, 40 to 60hp outboards make easy work of moving heavily loaded boats.

FourStroke Advantage

Comfort 
With a balanced powerhead and sophisticated, vibration-dampening cowl design, Mercury FourStroke outboards deliver an exceptionally smooth and quiet ride at any speed.

Durability 
Premium corrosion-preventive technologies and durable components ensure FourStroke outboards can stand up to the most demanding marine environments.

Compact Design
Ideal for new engine setups or repowers, the slender width of a Mercury FourStroke outboard fits most transoms, including those with narrow engine wells and tight motor spacing.

Efficiency 
Explore farther and stay out longer thanks to impressive power-to-weight ratios, intelligent fuel systems and optimized fuel injection (on most models) that maximize performance from every drop of fuel.
