The new Mercury 90 HP EFI Fourstroke
Meet the newest members to Mercury’s FourStroke Family What if you could hang a lighter, mid-range FourStroke outboard on your transom without sacrificing speed, hole shot, driving experience or sheer pulling power? What if that outboard also delivered increased fuel savings, hassle-free maintenance and extreme reliability?
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.
At 2.1 litres, the all new Mercury 75-115hp has one of the largest displacements in its class.
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.
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.
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.
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.
