None More Durable. Or Efficient.
Tuned for max acceleration and throttle response.
Lightweight & Fuel Efficient: Mercury’s world-renowned engineering team has packed incredible power into these lighter, compact four-cylinder single-overhead-cam engines.
Worry-free: The same lifetime maintenance-free valvetrain design found in our 150 FourStroke engines makes the 75-115hp FourStroke outboards incredibly durable.
Powerful & Efficient: Less weight and high displacement mean Mercury’s new 75 - 115 FourStrokes generate abundant torque and immediate power. Because they don’t have to work as hard as heavier engines or those with lower displacement, these engines make boats plane faster, accelerate better and provide optimal fuel efficiency at cruising speed.
