  • Made of seawater resistant bronze, all shaft and bearing surfaces are CNC machined to 2/1000mm accuracy
  • Its hydrodynamic shape ensures low water resistance and thus less cavitation
  • Heavy-duty seal designed for separation of two media, combining excellent contamination protection and supreme sealing performance
  • Gear-damaging vibrations caused by the action of the twin propellers are minimized due to crucial vibration damping capacity of the seals
  • Easy to replace anti-electrolysis aluminium anode
  • Hardened spiro-conical gears, developed for us by leading German manufacturers. The precise elemental geometry leads to a quieter running of the gear sets and longer lifetime
  • EMS S90 represents the ultimate electrical maneuvering system for motor yachts and deep footed sailing yachts in the 12-16m size
  • This state-of-the-art twin propeller propulsion system generates greater thrust force in the same tunnel diameter than the preceding EMS S80 model
  • With blade tips swept back against the direction of rotation, while bending rearward in reference to the longitudinal axis, our propellers generate “ahead” thrust which almost coincides with “reverse” thrust, i.e. the thruster system is reliable for maneuvering in both directions
