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. The 115hp weighs 20 pounds less than its closest four-stroke competitor, making it the world’s lightest low-emissions outboard in its power range.
The same lifetime maintenance-free valvetrain design found in our 150 FourStroke engines makes the 75-115hp FourStroke outboards incredibly durable.
The larger Command Thrust gearcase creates a bigger footprint in the water, which provides more leverage to control your boat. The larger torpedo, combined with a bigger-diameter prop, can lift a heavy boat onto plane more easily and hold it there at lower speeds without impacting top speed.
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.
Quiet & Smooth
Customers tell us they can barely hear these outboards running – especially at idle – because Mercury® successfully reduced noise and vibration in these next-generation FourStrokes. The result is an ultra-smooth ride and the ability to enjoy nature without overpowering it.
