2021 Mercury 400 ROS For Sale – 15 in. Shaft

• Powerhead: The 400 ROS is the most powerful competition outboard ever produced by Mercury Racing. Structural upgrades incorporated into the 2.6L cylinder block and head ensure classic Verado durability, even on the enduring offshore race circuit.
• Cool Air Intake: The cool air intake grabs fresh outside air to feed the supercharger and cooler air means more horsepower for big performance gains
• Supercharger: The water-cooled supercharger uses the engine cooling system to reduce air temperatures and supercharger load, increasing supercharger durability and more importantly – POWER
• Charge Air Cooler: For even more power, the air is cooled one last time by the charge air cooler after the air exits the supercharger and before it enters the cylinder head for maximum performance
• Electronic Boost Bypass Control Valve: Electronically monitors boost pressure levels to self-compensate for environmental changes, delivering consistent power that you have to feel to believe
• Billet Midsection: Custom designed by Mercury Racing, the competition midsection lowers the engine’s center of gravity for enhanced handling particularly when powering into and out of turns as well as overall boat performance at race speeds
• Sport Master Gearcase: The Sport Master gearcase provides enhanced boat handling, speed and efficiency. Custom short shaft models in both right and left hand rotation.
• Custom CNC Propellers: All new five and six-blade CNC cleaver propellers designed specifically for the 400 ROS. The new props are available in 13, 15, 18 or 21 degree rake and a variety of pitch sizes for precision matching of engine to hull for maximum efficiency and performance.
• Styling: Bold new 400 ROS graphics customized with XCAT logo and color scheme. A lightweight, carbon fiber lower cowl conceals the transition of powerhead to midsection. Dual rigging tubes facilitate rigging of external systems.
• SmartCraft: SmartCraft integrated marine technology is the brains behind the operation and the backbone for leading technologies like Digital Throttle & Shift. SmartCraft links the engine, controls, steering, and displays to provide data to keep the user informed of engine diagnostics and performance.
