FourStroke Performance Data
Smooth & Quiet
Optimized from the cowl to the mounts to minimize noise and vibration, Mercury FourStroke outboards are exceptionally quiet and smooth. The 75 to 115hp engines are quieter and smoother than any competing outboards on the water.
Powerful Torque
High-displacement powerheads and lightweight designs combine to deliver instant acceleration and exceptional overall performance.
Lighter by Design
The 115 and 150hp FourStroke outboards are the lightest in their class, enhancing fuel efficiency and speed for a wide range of boat types.
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.
