Mercury 115 HP EFI Fourstroke


Mercury 115 HP EFI Fourstroke

Unthink everything you know about performance. True power isn't just about speed and acceleration, it's determined by - displacement, torque, power to weight, size, friction resistance, gearcase, overall design and engineering.

It's these finer details that come together to make our all new FourStrokes unbeatable, against all comers. For stronger acceleration, lower planing speeds and improved tow sports capability, you won't find better.

Larger Displacement
At 2.1 litres, the all new Mercury 75-115hp has one of the largest displacements in its class. Our 115hp is the lightest in its class - it has a similar weight to the 75-90hp, but it offers over 30% more displacement?

?UnExpectedly Compact

Mercury's all new 75-115hp FourStrokes redefine smart marine engine design with simpler lines, lightweight, durable new materials and fewer moving parts than competitive FourStroke engines.

Cutting-edge engineering has packed incredible power into a light, compact package, making them tough, durable and efficient. 

Lightest 115hp FourStroke on the planet

A low profile, lighter weight engine is compact, improves power-to-weight, and reduces the overall package weight of the boat, allowing you to take full advantage of the engine's torque for acceleration.

The compact size also means older boats that were not initially designed for the weight of heavier 4-Strokes can now be repowered and reborn to perform at their best.

UnCompromising Reliability

Built tough and built to last, the all new 75-115hp FourStrokes have been tested
mercilessly to make them more reliable. From vicious log strikes to saltwater spray booths - the tougher the test, the tougher the engine. 

We make sure all Mercury customers benefit from:

 UnDeniably Fuel Efficient

More displacement means the engine doesn't have to rev as hard to produce the power, ensuring better fuel economy and a FourStroke that powers your boat without even raising a sweat, so throttle back and enjoy longer time on the water.

 Fuel Efficient TS

UnBelievably Smooth and Quiet

With Mercury's all new 75-115hp FourStrokes, everything possible has been done to reduce engine noise, vibration and harshness, to deliver the most pleasant driving experience of any outboard in their class.

New innovations include:
- Quiet Trim Pump System               - Top Mounted Throttle Body
- Refined Clutch System                  - Sound Absorbent Cowl Design
- Unique Focussed Mount System - Tuned Idle Exhaust Relief System


Superior Corrosion Protection

Mercury FourStrokes deliver powerful saltwater protection by using stainless steel components, hard anodizing, engineered polymers, and an exclusive multistep painting and coating process. Saltwater maintenance is made easy in the 75-115hp models with the innovative freshwater flush. And only Mercury offers a three-year limited corrosion failure warranty.
