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.
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.
