Intuitive, Innovative Features

Electronic Fuel Injection (EFI)

From the moment you crank the engine to the moment you drop the throttle, EFI technology (on 8 to 20hp outboards) responds with instant power. Surefire starting in all weather conditions. Smooth, efficient acceleration. Maximum fun.

Advanced Tiller

With a range of adjustments, easy-to-reach controls and the flexibility to be set up for left- or right-handed operation (on select models), Mercury tiller handles put you in complete command of your adventures.

Battery-Free EFI

Go farther confidently with battery-free EFI technology, included with manual-start 8 to 20hp outboards. It lets you enjoy the flexibility of portability, without needing to bring along a cranking battery.

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 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.
