Verado 400R



The New Standard

of Performance



If your thing is massive torque, instantaneous power and an intuitive control experience, there are four little numbers you should know.

1650. It comes race ready to dominate everything on the water. The 9.0 liter quad cam, four-valve engine delivers Godzilla-like power throughout the RPM band.

Larger turbochargers provide greater airflow for enhanced power and torque. SmartCraft Digital Throttle & Shift (DTS), provides big power with luxury-car-like drivability. Racers will appreciate Mercury Racing's proprietary pulse-separated exhaust tuning which keeps turbos "spooled up," virtually eliminating throttle lag and low-end torque deficit.



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





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





Guide Plates

Standard on all 400R models, the stainless steel guide plates stabilize the engine and Advanced Midsection for improved durability and rock solid handling at high speeds and in rough seas


Engine Mounts

High performance engine mounts designed in conjunction with Mercury's exclusive Advanced Midsection for the perfect combination of handling and overall running quality




A big part of what makes the 400R so great is the suite of technologies that support the Verado platform. SmartCraft integrated marine technology is the brains behind the operation and the backbone for leading technologies like Digital Throttle & Shift and Joystick Piloting for Outboards. SmartCraft links the engine, controls, steering, and displays to provide data to keep the user informed of engine diagnostics and performance.



Digital Throttle and Shift is a fully electronic throttle and shift system that offers smooth and predictable shifting and instant throttle response, similar to a modern sports car. DTS reduces the loud "clunk" associated with mechanical shifting for a high quality experience. Mercury Racing Zero Effort controls with Shadow Mode offer the ability to throttle and shift up to four engines with just two throttle and two shift levers for easier control at higher speeds



Joystick Piloting for Outboards

Running full throttle in the open water is what the 400R was designed to do, but docking a large boat in wind and current can sometimes be a challenge. Joystick Piloting for Outboards takes away the anxiety by combining throttle, shift and steering into one easy to use joystick which is designed for maximum maneuverability at lower speeds. The 400R gives you maximum performance at high and low speeds with Joystick Piloting for Outboards.
