Whether your day calls for a vacation or a voyage, a Mercury 75 to 150hp FourStroke outboard is the perfect accessory for your next adventure. They feature efficient, lightweight designs that ensure no power goes wasted – the ideal way to get wherever you want to explore next.

High-Output Alternator

A powerful alternator – 60 amps on the 150hp outboard and 35 amps on 75 to 115hp outboards – helps keep batteries charged and your onboard electronics running all day.

Command Thrust Gearcase

Available for the 90 and 115hp outboards, the Command Thrust gearcase is designed to turn larger props. It helps get heavy boats on plane more easily and hold them there at lower speeds without impacting top speed.

Electronic Fuel 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 capability.

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.

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.
