The Verado Advantage

Adaptive Speed Control
Adaptive Speed Control 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 care of the rest.

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.

Effortless Control
Digital Throttle & Shift (DTS) delivers 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 confidence wherever the water takes you.

Exceptionally Smooth & Quiet
The rugged, refined Advanced MidSection (AMS) mounting system cradles the powerhead to isolate vibration, while careful tuning dampens induction sounds and nearly eliminates injection noise. So you can enjoy your conversations while cruising comfortably.

Precision Gearcase
At high speeds, the hydrodynamic gearcase slips effortless through the water, maximizing efficiency and stability. At low speeds, its large-diameter Revolution X™ prop grips the water, giving you confident handling around the docks and providing instant hole shots when you need it.

Lightweight & Efficient
V10 Verado outboards are calibrated to deliver full performance on 87-octane fuel with efficiency-enhancing features such as a closed-loop fuel system and Advanced Range Optimization (ARO) that help extend your range.

Easy Maintenance

Mercury Verado outboards are thoughtfully designed to minimize maintenance and ensure you get the most joy from your time on the water. An electronic oil sensor handles routine engine oil checks for you, automatically verifying the oil level and notifying you on a connected multi-function display. When oil is needed, the industry-exclusive access door on the top cowl takes the hassle out of the job, allowing you to top off without removing the engine cowl. Color-coded touch points inside further speed up the process to get you underway faster.
