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.

Effortless Control
Digital Throttle & Shift (DTS) delivers smooth, quiet shifting and instant throttle response with zero hesitation. Combine that with joystick piloting and integrated power steering for the ultimate in comfortable, confident control.

Exceptionally Smooth & Quiet
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.
