Four Stroke 75-150 HP

Mercury Four Stroke 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.
Powerful performance and lightweight design go together like the open water and a sense of adventure.
Great for deck, inshore fishing, bass, aluminum tiller, runabout open bow, inflatable rigid hull, and fish & ski boats.
Made to provide outstanding acceleration and throttle response.

Texas Marine OUTBOARDS

Designed For Effortless Exploration.

For decades, the start of a Mercury FourStroke outboard has also meant the start of an adventure. With innovative engineering and refined performance, our 25 to 150hp engines carry on that same pioneering legacy. Mercury FourStroke outboards feature efficient, lightweight designs that ensure no power goes wasted. So whether your day calls for a vacation or a voyage, a Mercury FourStroke outboard is the perfect accessory for your next adventure.
