SX50 Compact External Stern Thruster, 12v 50kg/110lb Thrust On-Off, up to 2" (50mm) transom thickness

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

The SX50/140 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.

Features: 

To provide reliable and safe thruster installations in more boats, we offer modified versions of our DC electric thrusters in watertight housings for use in stern and other locations that may get wet or be exposed to gasoline fumes. These thrusters are fully ignition protected (ISO 8846) for use in boats with gasoline engines. They have a hermetically sealed composite housing around all electric parts. This provides the ignition protection as no gasoline fumes can enter and be ignited by sparks.

The other advantage is that the electric parts that could be damaged by water are also covered and protected, making these thrusters the ideal choice for other stern thruster installations where it is difficult to ensure that the thruster will always remain dry.

The gearhouse / drive legs of most Sleipner DC Electric thrusters are now fully galvanically isolated / separated from the electric motor and motor bracket. This ensures that even if there is an accidental short circuit or a current leak for other reasons, the immersed parts are not effected as they could be with direct electric contact.

  • Achieved by composite bushings around the bolts and beneath the washers and a bushing in the motor bracket electrically isolating the drive housing from the motor bracket.
  • Available on DC electric models with flexible couplers only, where the flexible coupler provides galvanic separation of the motor and gearleg shaft.
Side-Power Sealed Drive

Sealed drive lubrication

Sealed gearleg with long-life "mechanical" seal where highly polished ceramic and carbon surfaces form the only moving sealing surfaces, ensuring protection against damaging water intrusion into the gear leg. Pre-filled with special gear oil for lifetime lubrication.

  • "Mechanical" seals with surfaces of ceramic and carbon for ultimate security against water intrusion

Single propeller

A properly engineered single propeller system will be the most energy efficient thruster. Its compact design fits easily into narrow bows making it the perfect match for our smaller models. With more than 60.000 single propeller thrusters in use, the Sleipner single series system has proven its reliability.

Side-Power Q-prop™

Q-propeller

The new 5 blade special skew propellers are the result of over 2 years of development work and thousands of tests. They have been designed to reduce the noise level, while maintaining the exceptional efficiency of the old 4 blade Sleipner propellers. This goal was achieved, and we even chose to make them a little bit more aggressive on some models, increasing the thrust on some thrusters about 5%. Please see individual information on each new thruster for more details.

  • Noise reductions of up to 75% measured in controlled environments
  • The expected and tested normal noise reduction in average installations: 20-40%
  • Will be delivered on all Sleipner models except models with 300 mm and 385 mm tunnel diameter
  • Upgrade kits are available for most SP series thrusters with special adaptors
Side-Power Intelligent Power Control

Intelligent power control

The Sleipner unique thruster controller that intelligently protects the thruster from potential inherent problems in all high current applications as well as user faults. It includes several important safety features imperative in a product with such high power, run by DC electrics, as a thruster.

  • Provides delay between drive directions
  • Monitors solenoid functions to reduce the chance of solenoid lock-in
  • Will stop the thruster in case of a lockedin solenoid, without extra user action and even without controlling a main switch.
