Easy Portability
Simple to install and lightweight, 2.5 to 20hp FourStroke outboards let you bring along the fun wherever it’s needed.
Convenient Maintenance
We made maintenance easier with features like a no-spill oil change system, easy-out fuel filter and lifetime maintenance-free valve train
FourStroke Performance
Flexible, Versatile Power
A variety of remote and tiller controls, manual and electric start, and power or manual trim (options vary by horsepower) let you set up your engine to match your boat and favorite on-water activities.
Small but Mighty
With their high torque and rugged durability, Mercury portable outboards are ideal for powering a range of johnboats, small aluminum fishing boats and rigid inflatables, as well as for secondary power on sailboats.
Lighter by Design
Proprietary alloys and advanced cowl materials allow Mercury FourStroke outboards to deliver heavyweight performance in a lightweight package.
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.

Warranty & Maintenance
Limited Warranty
World-class marine products backed by world-class warranties. We stand behind everything we build, and we go the extra mile to make sure your Mercury experience is the best it can be – on the water and off.
Mercury Product Protection
Mercury Product Protection is an extended service contract for your Mercury engine that covers certain expenses caused by defects in materials and workmanship after the Mercury Limited Warranty expires.
Maintenance
Whether you keep your outboard at a remote outpost or in your garage, we’ve made maintenance easier. Our maintenance-free camshaft requires no regular service and no valve leash adjustments. Ever. For the life of the engine. Changing crankcase and gearcase oil is a snap, too. The oil-filter drip tray (on EFI models) and easy-drain design minimize messes. And the gear lube will fully drain from any tilt position. Less hassle leaves more time for fun.
