Intuitive, Innovative Features

Exceptionally Smooth & Quiet

The rugged Advanced MidSection (AMS) mounting system cradles the powerhead to isolate vibration, while expert tuning minimizes engine noise and optimizes the sound quality for a more enjoyable boating experience.

Effortless Operation

Mercury Digital Throttle & Shift (DTS) controls deliver smooth, quiet shifting and instant throttle response, with zero hesitation. Advanced electro-hydraulic steering enhances the driving experience at all speeds, providing complete control and confident handling wherever the water takes you.

Joystick Piloting for Outboards

The industry’s most advanced Joystick Piloting system makes maneuvering in tight spaces as simple as nudging the joystick whichever direction you want the boat to go. The SmartCraft system takes it from there, providing unparalleled low-speed control for easy, confident docking.

Adaptive Speed Control

The Adaptive Speed Control (ASC) feature lets you maintain engine rpm despite changes in load or conditions. Climbing large swells is easier. Cruising at low speeds is smoother. Carving out tight turns is effortless. You just point the bow toward your destination, and Verado takes it from there.

Advanced Sound Control

Choose the sound that moves you with the industry-exclusive Advanced Sound Control feature. It lets you toggle between a whisper-quiet exhaust tone or a throatier growl at startup and idle, for those times you truly want to hear the horsepower.
