SX100/185T 12V External Stern Thruster, 100 kg (220 lbs), 185mm (7.3″) tunnelThe SX100/185T is the perfect choice for boats where the inside configuration of the boat’s stern makes a standard thruster installation impractical. When fitted with the optional cowls, the stern thruster assembly is perfect for boats with twin stern drives. The special cowls enable good performance by diverting the waterflow past the stern drive legs which normally blocks the waterflow and the thrust.


Other items to consider when purchasing a new thruster:

  • Control Panels and Remote Controls
  • AutoMainswitch, Battery Disconnect, Fuse & Fuseholder
  • 4-Wire Harnesses (when not using AutoMainswitch)
  • 5-Wire Harnesses (for use with AutoMainswitch)
  • Note:  For use between stern drives, add the Side-Power Stern Tunnel Cowls that are sold separately.

Features & Benefits:

  • Pre-assembled thruster unit in a rugged GRP casing for simple external installation.
  • Waterproof and ignition protected: can be installed in gasoline-powered boats.
  • Requires only small holes in the boat’s transom for power/control cables and mounting.
  • Serviceable when boat is lifted (refitted with new O-ring seal).
