          Sleipner Side-Power SX50 Compact Stern Thruster

          Item # 883351


          The brand new SX series are the world's most compact external bow and stern thrusters that fit where others won't and offer a number of attractive benefits for boat builders as well as retrofit installations. Its versatile installation possibilities and compact size make it a perfect choice for vessels where the inside configuration does not allow a standard thruster installation. Available in 35 and 50 kg thrust as On/off and PRO (variable speed) versions suitable for boats up to 11 m / 37'.

          As the Side-Power engineering team has accumulated a vast amount of know-how about externally mounted thrusters over the years, this knowledge has now resulted in a brand new generation of external thrusters. The new generation has been improved in virtually every component and engineered for a more effective manufacturing process in order to reduce production cost and thereby price. Further more, when used as a stern thruster, these models will be the most compact ever. So, if you could not fit a stern thruster before, it might be a good idea to check out our latest generation of external thrusters.


          • The world's most compact external thruster
          • Energy efficient and long run times -- The external placement of the unit provides a more efficient water cooling and allows longer duration per cycle of the unit than with traditional bow and stern thrusters. Even longer run times in PRO (variable speed) version when run at reduced speed
          • Versatile installation -- The design of the new SX models allows for a large range of different installations as bow and stern thruster for both motor boats and sail boats. Easy installation with no GRP work necessary
          • Patented Intelligent Power Control (IPC) protection as standard
            • Provides delay between drive directions
            • Monitors solenoid functions to reduce the chance of solenoid lock-in
            • Will stop the thruster in case of a locked-in solenoid, without extra user action and even without controlling a main switch
          • Integrated PMDC motor for reduced size and optimal cooling
          • Full aluminum body. Various alloys used for specific purposes. Hard coated and treated for optimal corrosion protection
          • Optimized tunnel geometry for better performance and reduced noise -- Optimal efficiency of bow model results from a shorter transverse channel and ideal leverage which is created by deeper and more distant positioning away from the pivot point, giving up to 40 % higher efficiency than with conventional tunnel
          • Sealed gear house -- no oil changes needed
          • All external stainless parts galvanically isolated from wetted aluminum surfaces
          • Safety -- Ignition protection. Can be installed in stern locations/ on compartments with high octane fuels due to hermetically sealed housing. ISO 8846 and UL 1500 certified. Galvanic isolation kit for metal/aluminium hulls and safety protection grids available as accessories
          • Very Quiet -- With a short and optimally designed tunnel, vibration absorbing sleeves on all hull connections, 5-bladed Q-prop™ and the fully submerged unit, the thruster operates remarkably quiet with less vibration
          • By adding the Hydropod low drag cover, the new SX models can be mounted under the hull in the water flow for low- and mid-speed vessels. The optimal design adds minimal drag and will in most installations not be noticeable. The in-flow configuration is perfect for boats where it is difficult to fit a tunnel thruster or for example as a stern thruster for cruising sailboats


          • Thrust at 12V/24V: 62kg (136lbs)
          • Thrust at 10.5V/21V: 50kg (110lbs)
          • Typical boat size: 8-11m (27-37ft)
          • Tunnel inner diameter: 140mm (5.5in)
          • Propulsion: Single
          • Power at 10.5V/21V: 2.8 kW (3.7hp)
          • For DC System: 12V
          • Weight: 15.3 kg (34lbs)
          • Min. battery capacity (CCA 12/24V): 380A
          • Signal type: Analog

          All Side-Power thrusters gets their thrust rating from the actual performance you can expect in a boat - at the voltage a normal installation will provide at the thruster. We have chosen to use the net performance at 10.5V/21V, but we also list the effect at 12/24V for comparison.

          All battery CCA ratings are stated with the DIN rating, multiply by 1.9 to to get the SAE equivalent (at 0°F, ABYC standard).
