The Power of New
Whether you choose a high-performance Mercury Verado; a direct-injected (DI) two-stroke OptiMax; or a high-quality FourStroke, you can't go wrong with a new Mercury engine to repower your boat.
View Mercury Outboard Models
Genuine new factory outboard powerheads are available just like the ones used to produce new Mercury outboards. More than a bare powerhead, these new engines feature the latest engineering updates and are the exact same pieces used for producing new Mercury outboards. So if nothing less than new will do, then come to the source!
If your outboard discovered how shallow the water can be the hard way, then you can discover how quickly a Quicksilver gearcase can get you back on the water. These are genuine new factory units just like the ones use to produce new Mercury outboards. We cut our own gears, so the dependability and reliability of genuine Mercury gearcase has you covered.
Factory-fresh units, gearcases from Quicksilver come with a one-year factory-backed limited warranty. Major Assembly Protection from Mercury Product Protection is also available to provide up to two years of additional coverage

Reliability. Out here, it's everything
At Mercury, we engineer, build and test reliability into all our products. We always have, and we always will. Because whether you've got four 300hp Verados spanning your transom or a 2.5hp FourStroke on the back of your inflatable boat, consistent, reliable engine performance is a must.
So before we put our outboards to the test in the real world, they endure test after test in our state-of-the-art testing center. All so you can take to the water with confidence every time, no matter what. Because when you're on the water, reliability is more than just a word. It's peace of mind.
Mercury engineers all of its outboards for tough, long-lasting performance; Here are some specific examples…
The Mercury Verado features a unique Long Bolt Engine Design to keep the powerhead in a state of constant compression, with rubber dampening to minimize the effects of engine vibration. Fewer parts moving means fewer chances for wear and tear.
Our OptiMax family incorporates the best gearcase design priciples by featuring a heavy-duty prop shaft and Mercury-patented dual water pickups on the front end of the torpedo for a constant flow of cooling water. And every 75-115hp Mercury FourStroke features a fully filtered air intake to protect internal engine components, along with our advanced antidrainback oil system to assure instant lubrication on start-up.
State-of-the-Art Test Center
To help make sure our engines are the best you can buy, we test marine engines 24 hours a day, seven days a week. We monitor everything from fuel economy, horsepower, and RPM to noise and vibration levels, and everything in between.
Maintenance-Free Valve Train
All Verado and 75-115hp FourStroke outboard engines feature a valve train with a unique, robust, overhead cam design, making it incredibly durable and, unlike many competitors' four-strokes, maintenance-free for life.
Superior Corrosion Protection
Mercury engines are built with more stainless steel components, which translates to saltwater durability, longer intervals between maintenance, and lower cost of ownership.
Peace of Mind
Mercury's Engine Guardian system uses more than 40 sensors to monitor all the major functions of your engine. If the proactive operator-warning system detects a potential problem – such as over-revving, overheating, or low oil pressure – Engine Guardian sends out an alert and automatically reduces engine power enough to prevent damage, but still allows you to get to shore.
