2021 Mercury Marine® FourStroke 90
Embrace Possibility.Mercury FourStroke outboard motors are incredibly powerful and efficient, and they feature a wide range of applications. Crafted for less weight and high displacement, they generate abundant torque and immediate power. And because they don’t have to work as hard as heavier engines or those with lower displacement, they make boats plane faster and accelerate better, and they provide optimal fuel efficiency at cruising speed.
Made to provide outstanding acceleration and throttle response. Great for deck, inshore fishing, bass, aluminum tiller, aluminum console, runabout open bow, inflatable rigid hull, and fish & ski boats.
