FourStroke 175 - 225hp3.4L V6 and 4.6L V8Reliability, flexibility, power and efficiency – all within your reach. Backed by decades of marine power innovation and product leadership, Mercury V8 and V6 FourStroke outboards deliver legendary performance and forward-thinking technology. FourStroke outboards are built for any body of water and a wide variety of boats. |
Adaptive Speed ControlThe Adaptive Speed Control feature lets you maintain engine rpm despite changes in load or conditions. Climbing large swells is easier. Cruising at low speeds is smoother. Carving out tight turns is effortless. |
Easy to MaintainThe 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. |
Industry-Exclusive Battery Management TechnologyWhen battery voltage is low, the engine will automatically increase idle rpm to boost alternator output and charge batteries to the proper level. |
Smooth and QuietMercury V6 FourStroke outboards deliver a smoother, quieter ride than any competing outboard, at any speed. |
Ample Charging OutputA powerful alternator delivers 85 amps of charging power at wide-open throttle – perfect for keeping onboard electronics running long into the fun. |
Quick AccelerationThe 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 EconomyA 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 & QuietThe V6 200hp FourStroke outboard is 30% quieter with 50% less transmitted vibration than the leading four-stroke competitor. |
ComfortWith a balanced powerhead and sophisticated, vibration-dampening cowl design, Mercury FourStroke outboards deliver an exceptionally smooth and quiet ride at any speed. |
Compact DesignIdeal 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. |
DurabilityPremium corrosion-preventive technologies and durable components ensure FourStroke outboards can stand up to the most demanding marine environments. |
EfficiencyExplore 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. |
