The SX35 Compact Stern Thruster is a 12V stern thruster that provides 35 kg of thrust. Designed to offer a compact and efficient solution, it enhances the maneuverability and control of the boat, especially in confined spaces.

SX35/140 12V Compact On/Off External Stern Thruster, 35 kg (77 lbs), 140mm (5.5″) tunnel, Fits transoms up to 2″ (50mm) in thickness

Use the Hydropod Kit #SM150536 for installation as a Bow thruster or in water flow

The SX35/140 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)
  • For use between Outboards, Stern Drives, or other shallow applications like Ski Boats, consider adding the Cowls SM130773, or Grates SM130789.
  • For Isolation on Aluminum/Steel hulls or for spacing, consider an Isolation Block,  SM148170 50mm or SM148171 10mm.


  • Simple external installation with no GRP work necessary.
  • Compact unit, energy efficient and long run times
  • 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).
  • Available in PRO version with variable speed control
