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.
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.
High performance engine mounts designed in conjunction with Mercury’s exclusive Advanced Midsection for the perfect combination of handling and overall running quality.
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.
Seven different colors are available for the graphics package on the Cold Fusion White 400R and are designed to reflect your personal style or match the color palette of the boat. Either way, heads will turn, even if you won’t be in view for long. Phantom Black available only with Red / Carbon graphics package.
