400 ROS Custom Rigging Requirements:
The electric fuel pump and oil sump for the competition 400 ROS are boat-mounted. As such, Mercury Racing has developed special 400 ROS rigging kits which contain the dry sump oil tank (#8M0115428) and the electric fuel pump kit (#840368A1), and these are required to complete the 400 ROS installation (one of each kit per engine). In addition, the standard dual engine rigging kit (#8M0101415) which contains the DTS Zero Effort system and other necessary harnessing and components is required, and SmartCraft instrumentation must also be ordered separately. Finally, the 400 ROS requires a custom after-market hydraulic steering system and tie bars, and is not compatible with the standard Verado power steering. The remote-mounted 12-volt trim pump (#818377A2) is not included with 200XS or 400 ROS engines.
