PRODUCT AWARENESS: The New Mercury Four-Strokes


Mercury Marine is asking customers to “unthink” everything they know about four-stroke outboards with the introduction of its all-new 75, 80, 90, 100 and 115hp four-stroke models. At 2.1L, the new Mercurys have one of the largest displacements in their class and deliver up to 23% more torque over previous four-stroke models. Cutting-edge engineering has delivered a compact and low-weight package from a 2.1L, four-cylinder, eight-valve, low-friction valve train with single-overhead-cam design, to provide outstanding torque and horsepower. In fact, despite their larger capacity, the new 115hp four-stroke is very light – 9kg lighter than the next closest competitive four-stroke product – and all five new four-strokes even trump Mercury’s popular 1.5L OptiMax direct-injection models in terms of weight. Exceptional fuel efficiency is also delivered, with the new 115hp model offering up to 14% better cruise-speed economy than Mercury’s previous four-stroke model. The new Mercury four-stroke engines are based on the same architecture as the reliable and popular Mercury 150hp four-stroke, highly regarded for its simplicity, efficiency, and strong balance of durability and performance.  And unlike competitive four-strokes, the lower friction valve train is maintenance free for the life of the engine, meaning less time in the workshop and more time on the water. As with all Mercury engines, the new 75-115hp four-strokes have been tested to extremes. Over 17,000 hours of testing have been conducted, involving: vicious log strikes, saltwater spray booths, high-humidity chambers, hot-and-cold water temperatures, and hours of endurance testing. Choose between two different gearcase options An all-new, world-class hydro-dynamically designed gearcase comes as standard, decreasing drag by 15% to improve efficiency and performance; ideal for lighter-performance oriented hulls. However, for heavier boats, boats that tend to run “wet” (more hull surface remaining in contact with the water after its planed), pontoons and houseboats, the new robust Mercury Command Thrust gearcase facilitates added thrust, maintains slower-planing speeds in rough water and simply additional lift. Available with the 90hp and 115hp four-stroke outboards, the Command Thrust models (previously known as “Big Foot”) use the same bigger gearcase housing as the Mercury 150 four-stroke, but with an all-new 2.38:1 ratio ideally suited for heavier boats. The 90 and 115hp Command Thrust models are also available with left-hand rotation for improved handling and docking in dual-engine installations. With the Command Thrust’s larger, heavy-duty gearcase, outboards can be fitted with the larger-diameter class of V6 propellers that go with it, such as Mercury’s popular Enertia series. Smooth and quiet operation

Mercury’s new 75-115hp four-stroke outboards each feature a tightly-sealed top cowl and idle relief muffler system which lessens high-frequency exhaust noise. A top-mounted throttle body fine-tunes intake noise, while the exclusive Focused Mount System greatly reduces vibration. Even the trim pump is designed to run significantly quieter, and a new clutch system reduces shock while shifting into gear. All these features deliver a smoother, quieter, more pleasant boating experience.

These new outboards also feature Mercury’s industry-leading anti-corrosion protection that includes Mercury’s exclusive XK360 low-copper alloy, extensive use of stainless steel components and the MercFusion paint process, which is engineered specifically for the harshest marine environments. Mercury backs up its corrosion protection with a three-year limited warranty.

A full range of Mercury’s dedicated SmartCraft digital gauges, including SmartCraft SC1000 gauges, VesselView4 and VesselView7 screens, can be optioned with these engines, along with a wide range of propellers to help boaters get the most from their packages.
