Verado Advantages

Legendary Power

Even with heavy loads or in tough conditions, V10 Verado outboards barely break a sweat. Their impressive 5.7 liters of displacement make easy work of powering boats out of the hole and up to speed.

Active Trim

Active Trim automatically trims your boat, which simplifies operation while improving performance and decreasing fuel costs. With Active Trim, both new boaters and experienced captains can achieve perfect trim without constantly monitoring and adjusting the trim control.

Smoother and Quieter

Verado engine designs virtually eliminate transmission of vibration to the boat, while acoustic engineering not only prevents harsh noises, but it also tunes the engine for an optimal, pleasant boating experience.

Corrosion Resistance

Advanced alloys. Durable coatings. Sealed electronics. Easy-to-use freshwater flush system. Verado outboards come packed with premium corrosion-preventive technology that enables them to stand up to the most demanding marine environments.

Joystick Piloting for Outboards

Mercury Joystick Piloting provides fingertip control of throttle, shift and steering so you can dock precisely, safely and with confidence. Move forward, backward, sideways, diagonally or spin the boat on its own axis with total control despite wind or current.
