SX100 external stern thruster 12V

The SX100 external stern thruster 12V (item code SX100/185T-12V) is an externally mounted Sleipner stern thruster for boats up to 55 ft with twin stern drives. It delivers 100–116 kg of thrust, and special cowls divert the water flow past the stern drive legs. The unit is delivered pre-assembled, wired and sealed in a waterproof box, requiring only a small hole in the transom for power and control cables.

Key features

• Hydrodynamic shape and short flow channel for minimal water resistance at speed
• External motor placement reduces noise emission by about 80%, avoids border cavitation and gives more efficient water cooling for longer run time per cycle
• Ignition protected as standard – suitable for petrol-powered boats
• Q-PROP™ five-bladed skew twin propellers for reduced noise
• Patented intelligent power control: minimal delay between drive directions, solenoid monitoring and automatic stop on solenoid lock-in
• Overheat protection with automatic shut-off
• Galvanic separation of immersed parts from the onboard electrical system
• Sealed, lifetime-lubricated gearleg with ceramic/carbon mechanical seal
• Analog control with colour-coded plug-and-play signal cables
