The 400R features a custom cold air induction system for improved air flow and power development while significantly reducing intake noise for improved sound quality.
An all-new water cooled supercharger is designed to reduce intake temperatures and significantly increase air density. This enables the engine to generate unprecedented torque and unmatched acceleration all the way from the lower end of the power band up to the 7,000 rpm maximum engine speed. Electronic knock control enables the engine to safely run on 89 octane (95 Ron) fuel when the recommended premium 91-octane (98 RON) fuel is not available to maximize performance.
The 400R is the first ever Verado to feature the race-proven Sport Master gearcase with low water pickups for added performance. The efficient and durable Sport Master greatly expands the application of the potent four-stroke. From single engine flats boats, traditional catamaran sport boats to multi-engine offshore center consoles – the Sport Master – in the correct application – will enhance boat handling, speed and efficiency.
To unlock the full potential of Sport Master, the 400R features stainless steel guide plates with composite wear pads on the Advanced Midsection for enhanced engine stability and improved handling at speed. The engine is also available with the standard Verado 5.44” HD gearcase for more traditional applications.
“Zero Effort” with Joystick Piloting (JPO)
The Verado 400R is the first Mercury Racing outboard to feature Joystick Piloting for Outboards (JPO) technology. Joystick Piloting takes the stress out of docking, maneuvering in tight spaces and operating in tight quarters by providing boaters 360-degree movement at their fingertips. JPO 400R models available exclusively with cambered Sport Master gearcases.
Mercury Racing’s ergonomic, high-style Zero Effort Digital controls go hand-in-hand with Joystick Piloting for an intuitive control experience – precisely signaling driver intent to the Digital Throttle & Shift (DTS) equipped Verado 400Rs. The DTS system also features one-touch Smart Start, automatic throttle synchronization and shadow mode for triple and quad engine applications (where two throttle levers operate all engines).
The 400R is available in both Cold Fusion white and the legendary Mercury Phantom Black. Cold Fusion white models come standard with Mercury Racing Blue accent colors. In addition, a total of seven custom colored accent decal kits are available on Cold Fusion White models to match a variety of boat graphics.
When we develop any high performance engine – we develop it as a complete system – including the propeller. The recommended props make use of all four hundred horses for unmatched performance on multi and single engine boats.
