FourStroke 40-60 hp

Intuitive, Innovative Features

High-Output Alternator

An 18-amp alternator helps keep batteries charged and fishing electronics humming long into the evening bite. 

Convenient Maintenance

We made maintenance easier with features like color-coded touch points, an easy-access water-separating fuel filter and an oil filter drip tray, which helps you get the job done with less mess. 

CommandThrust Gearcase

Designed to sit lower in the water and turn larger props, the available Command Thrust gearcase lifts heavy boats on plane more easily and holds them there at lower speeds without impacting top speed. 

Tiller Handle

With a range of adjustments, ergonomic controls and the flexibility to be set up for left- or right-handed operation, the available advanced tiller puts you in complete command of your adventures.

ElectronicFuel Injection (EFI)

From the moment you crank the engine to the moment you drop the throttle, EFI technology responds with instant power. Surefire starting in all weather conditions. Smooth, efficient acceleration. Maximum fun.

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.

FourStrokeAdvantage

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.
