  • 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 P100 is probably our most versatile bow thruster system. Excellent choice for 12-15m motor yachts and deep footed sailing yachts, whose owners require utmost reliability in virtually all environmental situations, yet appropriate for vessels up to 16m in length
  • Utilizing the same mechanical components as the even more powerful EMS P120, its smaller DC motor ensures better energy efficiency translating into lower amp draws and more compact installation size
  • Our skewback six-blade propellers generate less cavitation, which, in addition to the carefully chosen hydroacoustic design, results in great noise reductions
