2023 Mercury Marine® FourStroke - 90

RELIABILITY, PORTABILITY, AND POWER.

RELIABILITY, PORTABILITY, AND POWER.

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.

The lightest low-emissions outboard in its power range. Great for deck, inshore fishing, bass, aluminum tiller, runabout open bow, inflatable rigid hull, and fish & ski boats.

Enjoy the same lifetime maintenance-free valvetrain design found in our 150 FourStroke motors. Great for deck, inshore fishing, bass, aluminum console, runabout open bow, inflatable rigid hull, and fish & ski boats.
