New: Water-Cooled Supercharger

New: Water-Cooled Supercharger

The intuitive Verado 350 design taps into the engine’s cooling system to cool the supercharger and reduce the effort required to compress air, thereby increasing efficiency and durability. 

New: Cold-Air Intake

New: Cold-Air Intake

The Verado 350 can breathe! The cold- air intake system is designed to capture cool, fresh air from outside the cowl and deliver it directly and efficiently to the supercharger. The larger, straighter airflow path is a more efficient design that creates less turbulence. The unique labyrinth design in the top cowl keeps the powerhead dry. 

New: Lightweight / Compact Design

New: Lightweight / Compact Design

At just 668 pounds, the Verado 350 is 95 pounds lighter than its competition, and its compact design allows for 26" engine spacing and less stress on the transom. 

Geared Right.

Geared Right.

The ultra-robust 5.44-inch-diameter gearcase is built for offshore seas and provides extra lift for longer, heavier center consoles and walkarounds.

World-Class Design.

World-Class Design.

Our long-bolt design anchors the block and cylinder head to the bedplate and eliminates the effects of expansion and contraction. An exclusive oil cooler maintains optimal oil temperature to extend the life of the engine.

In addition, the Verado valve train is maintenance-free for the life of the engine

Joystick Piloting for Outboards.

Joystick Piloting for Outboards.

With a simple push or twist of a joystick it’s possible to maneuver a boat in virtually any direction – sideways, diagonally or spinning the boat on its axis.

Control dual, triple or quad Verado 250hp or 300hp outboards, even in challenging wind and current conditions. This system integrates seamlessly with SmartCraft® Digital Throttle & Shift (DTS) and electro-hydraulic power steering, while standard integrated autopilot provides Auto Heading and Waypoint Sequencing.

Also available with Skyhook®, a digital GPS positioning system which can hold a boat in position while fishing or waiting for bridges to open.

Smoothest, quietest.

Smoothest, quietest.

The inherently balanced in-line six-cylinder engine and our Advanced Mid Section (AMS) with perimeter mounts virtually eliminate vibration in the boat. Perfect for sneaking up on fish or cruising on luxury pontoons.

Driving Experience.

Driving Experience.

SmartCraft® Digital Throttle & Shift provides smooth, instantaneous, predictable and quiet shifting, as well as ultra-responsive throttle control, while true Power Steering (standard on six-cylinder models) delivers precision steering without undesirable steering torque.

Mercury “shadow technology” eliminates the hassle of grappling with multiple engine levers when running with triple or quadruple outboards. Shadow mode controls up to four engines with just two levers from as many as two helm stations.

White, Black, Your Choice.

White, Black, Your Choice.

In addition to standard Phantom Black, Mercury now offers 300hp and 350hp Verado outboards in two shades of white – Cold Fusion and Warm Fusion. The two new shades of Mercury White will complement almost any boat design or style.
