FourStroke outboards are easy to own, fun to drive and ready to explore.

FourStroke Performance Data

Quick Acceleration
The high-displacement, quad-cam design of the V6 FourStroke powerhead generates serious torque, especially at mid-range, for quick acceleration and exciting speeds.

Superior Fuel Economy
A host of efficiency-enhancing features such as Advanced Range Optimization (ARO), a closed-loop fuel system and a hydrodynamic gearcase optimize fuel economy so you can go farther on every tank.

Exceptionally Smooth & Quiet
The V6 200hp FourStroke outboard is 30% quieter with 50% less transmitted vibration than the leading four-stroke competitor.

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.
