MERCURY 400HP FOURSTROKE ROS

  • blank

Upon the heels of the highly successful Verado 400R outboard is its sinister competition relative, the Mercury Racing 400 ROS (Race Offshore).  The 400 ROS features the 400R powerhead mounted on an all-new race midsection, featuring the competition-proven Mercury Racing heavy-duty swivel clamp bracket assembly. A Sport Master gearcase transfers the 400 ROS’s massive power to the water. And to ensure every revolution counts, Mercury Racing has developed an all-new line of CNC cleaver propellers specifically for the 400 ROS.
