Mercury 300 HP Verado Six Cylinder – Every Verado in the range is built on one solid principle. To create a motor that is tough from top to bottom. With supercharged power in every Verado, the torque produced by the engine is nothing short of incredible. With greater torque through the entire rev range you receive awesome acceleration as well as being able to keep a heavily loaded boat on plane at slower speeds, and climb larger waves.

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.

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, 300hp or 350hp 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 and 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.

Power.

The instant boost of an intercooled supercharged system delivers tremendous hole shot, unrivaled mid-range punch and excellent top speed.

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.
