Mercury FourStroke outboards are made to unlock the inaccessible. To make light work of long journeys. The 9.9 FourStroke outboards empower you to enjoy the water on your terms and reach places you wouldn’t dare venture with other engines. They’re reliable, compact, lightweight, easy to install and simple to operate, while still delivering quick acceleration and impressive speed. The only thing missing is a destination.

We made maintenance easier with features like a no-spill oil change system, easy-out fuel filter and lifetime maintenance-free valve train

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.

Easy Portability

Simple to install and lightweight, 9.9 FourStroke outboards let you bring along the fun wherever it’s needed.

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.

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.
