Intuitive, Innovative Features
Adaptive Speed Control
Smooth and Quiet
Mercury V6 FourStroke outboards deliver a smoother, quieter ride than any competing outboard, at any speed.
Easy to Maintain
The exclusive Top Cowl Service Door simplifies routine maintenance, letting you check or add engine oil without removing the top cowl. An hour-based maintenance schedule decal is located under the cowl, providing a quick overview of routine maintenance.
Ample Charging Output
A powerful alternator delivers 85 amps of charging power at wide-open throttle – perfect for keeping onboard electronics running long into the fun.
Industry-Exclusive Battery Management Technology
When battery voltage is low, the engine will automatically increase idle rpm to boost alternator output and charge batteries to the proper level.
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.
