At a staggering 153 horsepower per liter, the all-new Mercury Racing Verado 400R outboard is the most powerful consumer outboard ever produced by Mercury and provides the highest power-to-weight of all other four stroke outboards in its class. This incredible achievement in power and efficiency was achieved through a number of advancements to the proven 2.6L Verado platform. This powerhouse is designed to complement the latest generation of high performance hulls.
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. Structural upgrades incorporated into the 2.6L cylinder block and head ensure classic Verado durability, even at this higher power output.
