Notes:

  • In some systems with dual steering rams in parallel, cylinder capacity is the total of both rams. Rams in series only require single capacity valve. Hydraulic steering systems with steering rams over 500cc require our larger constant running pump used in conjunction with the relevant ACU - contact Raymarine for details.
  • An authorised Raymarine dealer is best suited to installing a hydraulic autopilot system.
  • Type 0.5 suitable for Volvo D4/D6 Sterndrive applications.
