With the release of the first MerCruiser sterndrive at the Chicago Boat Show in 1961, Mercury Marine founder Carl Kiekhaefer forever changed the boating industry. Until then, outboards were the standard in marine engines, but Kiekhaefer's sterndrive allowed boaters to maintain outboard-like maneuverability in a package that offered unprecedented recreational boating power. With its already stellar marine reputation, MerCruiser quickly captured a commanding majority of the recreational market. Now celebrating its 50th anniversary, MerCruiser continues to lead the industry, guided by the same trailblazing ethic that inspired Kiekhaefer's historic first sterndrive.
For a half century, MerCruiser has been synonymous with unrivaled sterndrive and inboard performance. It all starts with a diverse selection of engines ranging from 135 to 430 hp, and more than 20 unique drive systems including Alpha One - the most popular sterndrive in the world. With the most complete lineup in the industry crafted by expert engineers, you're certain to find a MerCruiser engine-drive combination perfect for your boating style. Mercury enhances these offerings with complementary marine innovations such as Axius, the intuitive joystick-control system, and the stalwart corrosion protection of MerCruiser SeaCore. With decades of industry leadership and an eye to the future, the MerCruiser legend continues to grow.
Over these five decades, MerCruiser has worked tirelessly to maintain and grow its reputation as the most trusted sterndrive brand on the planet. MerCruiser has been able to stay at the forefront of marine engineering by remaining true to its four brand pillars: an unmatched product lineup, innovative integrated technologies, reliable and durable engines and drives, and an unrivaled service network.
Every boater has unique values and expectations for their on-water pursuits. That's why MerCruiser is committed to offering the most complete gasoline sterndrive product selection in the industry. With a wide range of engines, each with even deeper features and options, MerCruiser prides itself on having propulsion and technology systems for every boating style.
Nobody else offers a more comprehensive selection of catalyzed engines than MerCruiser. From the wildly popular 3.0L all the way up to the 8.2L big block, only MerCruiser has had the insight and wherewithal to invest in this game-changing technology to ensure its availability on a global scale.
The proven high-pressure common-rail fuel system provides a quiet, smooth ride with virtually no smoke or odors and up to 80 percent less noise than competitor diesel engines. Plus, you get impressive acceleration and precise throttle response with the QSD engine line.

Making Boating Enjoyable
You want the performance without the headaches. That's why Mercury is committed to developing innovative and sound technology that contributes to a more seamless boating experience. MerCruiser sterndrives feature Engine Guardian technology that monitors your engine's vitals to help protect your investment for the long run; power steering reduces the effort needed for steering while providing enhanced hull control at all speeds. Now, that's more like it.
Mercury's innovative joystick-control Axius system is the perfect remedy for boat maneuvering and docking woes. Axius allows you to dock in a safe and relaxed way, regardless of close quarters, cross currents or side winds. The intuitive and natural user interface gives you total boat control with one hand, meaning anybody can dock safely with total confidence.
SmartCraft: More Boating, Less Work
There has been one goal for the Mercury SmartCraft team from day one - to make boating more enjoyable through the use of boater-friendly technologies. SmartCraft technology enables engine components to gather and share information with each other and you, integrating this digital information to make monitoring your vessel, its engine and external conditions an easy, intuitive process. SmartCraft options such as DTS, MercMonitor, ECO-Screen and SmartTow help us accomplish our goal: maximizing the enjoyment you get on the water.
