Forget everything you know about FourStroke outboards. Ours change the game. Completely. They’re tougher, smaller, and lighter than any other FourStroke on the water. With a combination of performance and efficiency that will take your time on the water to a whole new level.
Embrace possibility. Adaptable, reliable, and able to outperform any outboard in its class.
FourStroke technology and Mercury. Always moving forward. With boater-driven innovations and technologies. Like electronic fuel injection. On-board digital monitoring that protects your engine. And a total commitment to corrosion protection utilizing hard-coat anodizing and a superior multi-step paint process. Mercury FourStroke engines have consistently set the bar for clean, quiet performance and low fuel consumption. Plus, no one has more models to fit your needs.
None More Durable. Or Efficient.
Tuned for max acceleration and throttle response.
Features may include:
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.
•Dry weight specification is for the lightest-version model. Comparative weights refer to base engines without oil, propeller or integral steering cylinder. Weights based on Owner’s Manual specifications.
•The same lifetime maintenance-free valvetrain design found in our 150 FourStroke engines makes the 75-115hp FourStroke outboards incredibly durable.
•Do you like to boat offshore even though you’re not in the market for a big boat? For the first time, Mercury is offering a 115hp FourStroke with left-hand rotation. Two of these mid-range monsters on your transom provide the maneuverability and get-home safety of higher-horsepower twins at a price that’s easier on your wallet. Unlike competitive dual 115hp engines, dual 115 Mercury FourStrokes are Command Thrust models, which swing V6-class propellers, such as Enertia series to deliver improved acceleration and better boat control in rough water.
*Available only on 115 hp
•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.
Quieter Than the Competition.
•The Mercury 115 FourStroke is quieter than the Yamaha F115B across the rpm band.
•At idle, the Mercury is four decibels quieter than the Yamaha – the Yamaha is 25% louder.
•At cruising speed, where normal conversations occur, the Yamaha generates almost 15% more noise.
•At wide-open-throttle, the Mercury is more than eight decibels quieter – the Yamaha is 50% louder.
•Testing performed by Mercury PD&E NVH staff at a Mercury Marine hemi-anechoic chamber (Sound Lab).
Smoother Than the Competition.
•The Mercury 115 FourStroke has less vibration and rides smoother than the Yamaha F115B.
•At forward idle, the Mercury’s vibration level at the driver’s seat is up to 50% lower than the Yamaha.
•On the transom, the Yamaha puts out nearly five times more vibration than the Mercury – both at cruise and at full throttle.
•Testing performed by Mercury PD&E NVH staff at a Mercury Marine test location on a 2013 Bayliner 170.
