You have to live it to believe it.

When Mercury set out to engineer the perfect outboard engine, we questioned everything: every number, every scenario, every detail. The result? Verado®, the world’s most reliable and advanced propulsion system. The six-cylinder Verado delivers an amazing driving experience, superior reliability, jaw-dropping power and acceleration, and the quietest, smoothest ride ever produced by an outboard.

Reliability

Gearcase Durability

Mercury Marine's commitment to testing and continual product improvement never stops. The most recent examples of this commitment are found in the new range of Verado gearcase offerings.

The new 5.44-inch gearcase - with strengthened internal components - is a larger, more robust version of the current 4.8-inch gearcase. The 5.44-inch gearcase is best suited for saltwater offshore boats that are run more aggressively, or in rough seas where the propellers frequently ventilate. Additionally, 23-foot or larger single-engine boats that weigh more than 5,000 pounds fully loaded will significantly benefit from this larger gearcase.

Lastly, the current 4.8-inch Verado gearcase continues to be the best choice for single-engine boat applications – including bass, freshwater multispecies, inshore flats and bay and pontoon boats. The 4.8" gearcase has a smaller hydrodynamic profile to ensure top performance on these boat types. This gearcase is available in right-hand rotation exclusively on a 20-inch and 25-inch 225 hp Verados as well as the new 250 and 300 Pro FourStrokes

Built Tough

Verado’s unique Long Bolt Engine Design provides ultimate durability by keeping the powerhead in a constant state of compression. The extra-long bolts (which pass through the bedplate, block, and cylinder) are supported by rubber dampening elements to minimize the effects of engine vibration.

Maintenance-Free Valve Train

Unlike many competitors’ four-strokes, Verado’s durable valve train stays maintenance-free for life, thanks to a unique and robust overhead cam design.

Long-Lasting Gearcase

The Verado gearcase was built to withstand high torque and speed, with unmatched impact protection. Also, only Mercury features Dual Water Inlets, including our patented low water pickup located on the front tip of the torpedo, ensuring a consistent flow of cooling water. The location of competitors’ pickups can prevent their engines from receiving a strong flow of cooling water due to weeds or air pockets.

Superior Corrosion Protection

Salt demands more. That’s why Mercury uses more stainless steel components than our competitors, as well as our exclusive low-copper XK 360 aluminum alloy that provides industry-leading protection against saltwater corrosion. The Verado supercharger features a marine-grade anodized aluminum housing. To top it all off, Verado is equipped with protective sacrificial anodes for superior protection at every level.

Performance

Awesome Torque

Verado’s Supercharged System delivers the torque big boats need for immediate planing, superior mid-range acceleration, and sustained planing at lower speeds.

Superior Combustion

The unique Verado Charge Air Cooler teams with the supercharger to deliver superior holeshot and acceleration by cooling the compressed air before it enters the combustion chambers. In addition, the Verado injection-molded Intake Manifold increases torque and power by delivering higher levels of airflow. As a result of all this, combustion is more complete, intense, efficient, and powerful.

Fuel Efficiency

Economy, Not Compromise

An enhanced power train gives you increased fuel efficiency and power without sacrificing reliability. Its robust design features forged pistons, precision-machined oil dams, eccentric grooved crankshaft main bearings, a unique intake cam profile, and an enhanced PCM (power control module) calibration.

More Air, More Power

The intake cam provides better top-end power by significantly improving airflow, allowing the engine to produce more power while working less.

Experience

Ultimate Control

The SmartCraft® Digital Throttle & Shift (DTS) System delivers automotive-like control, instant throttle response and smooth shifting by eliminating the hesitation of traditional mechanical cable systems. More than 50,000 hours of testing and nearly a decade of consumer use make DTS the most rigorously proven control system on the water.

Smooth, Precise Handling

The six-cylinder Verado features a unique Cradle-Mount Design with four oversized, calibrated elastomer mounts surrounding the powerhead to isolate and cancel vibration for an incredibly smooth ride. The advanced midsection (AMS) design incorporates a new steering-to-engine-axis geometry that greatly improves handling at higher speeds by eliminating the “crabbing effect” felt in large displacement fourstroke outboards. In addition, Mercury’s exclusive Power Steering system replaces the steering torque often felt with competitive outboards with a precise steering feel unique to Verado.

Unbelievably Quiet

The Verado multi-chambered Intake Sound Attenuator not only reduces overall noise by up to 14 decibels, it also tunes the engine sound to a more pleasing tone. Acoustic foam lining along the upper cowling and lower cowl absorbs high-frequency engine and driveshaft noise for a best-in-class sound rating.
