SX50 external stern thruster 12V

50kg thrust, on/off, <=150mm hull, w/controller

SX50 is our most compact thruster yet, with 50-62 kg thrust. Its versatile design allows for installation on boats of any hull shape up to 37 feet in length.

The external unit is easy to mount. No GRP work is necessary on boats with a hull thickness of up to 150 mm.

Properties

The Q-PROP™ has measured noise reductions of up to 75% in controlled environments. The five-bladed skew propeller reduces noise levels while maintaining exceptional efficiency. Some thruster models even see an increase in thrust power.

• The expected noise reduction in average installations: 20-40%
• Upgrade kits are available for most Sleipner thruster models with special adaptors

Sleipner’s patented intelligent power control provides a minimal delay between drive directions to reduce wear of the mechanical parts while monitoring solenoid functions. In the case of a solenoid lock-in, the thruster will automatically stop without extra user action or controlling the main switch.

Our ignition-protected products are compliant with ISO 8846 and ensure gasoline or other flammable fumes cannot enter or be ignited.

Waterproof housing for use in areas exposed to water.

When an unsafe temperature is detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating the thrust power to maintain temperature within safe levels.

Powered by direct current.

Sleipner analog signal cables with Plug & Play connectors are color-coded to match the wiring diagrams with high-quality connectors to ensure a correct installation.

Immersed parts exposed to seawater are galvanic isolated from the onboard electrical system, eliminating stray currents.

The thruster gearleg is pre-filled for lifetime lubrication and sealed using a long-time mechanical seal with ceramic and carbon surfaces for ultimate security against water intrusion.

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 thruster range. With more than 60.000 single propeller thrusters in use, the single propeller has proven its reliability.

Installation Manual, SX (SX35, SX50)

The compact SX models are available in four configurations that allow a vast array of installation options in the bow and stern of the boat.

1. Standard stern thruster

The most compact stern thruster on the market. Minimal height and width requirements.

2. Stern thruster with protection grids

An optimal solution for increased safety during watersport activities or for vessels used in waters with debris or drifting objects.

3. Stern thruster with cowls

Many vessels have a hull design requirement on the boat’s transom that disturbs the water flow to and from the stern thruster, thus making it less efficient. The adjustable cowls direct the water flow to be less disturbed, obtain a higher efficiency level, and allow a shallow installation closer to the waterline.

4. Hydropod bow- and stern thruster

With the hydropod low-drag cover, the SX 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.

Features

Ultra-compact
Fits where others won’t. The SX’s versatile installation possibilities and small size make it a perfect choice for vessels whose inside configuration does not allow a standard thruster installation.

Easy installation
Only requires drilling three small holes with a minimal footprint on the hull. No fiberglass work is necessary. Compatible with standard Side-Power products, control panels, and accessories.

Minimal noise emission
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 quietly.

Safety
Ignition protected. It can advantageously be installed in stern locations/ on high-octane fuel gasoline boats due to a hermetically sealed housing. ISO 8846 and UL 1500 certified. Galvanic isolation kit for metal/aluminum hulls and safety protection grids available as accessories.

Long run times
The external placement of the unit provides a more efficient water cooling and allows a prolonged duration per cycle of the unit than with traditional bow and stern thrusters. Even longer run times in the PRO™ version when running at reduced speed.

Optimal efficiency
The optimum efficiency of the SX models results from a shorter transverse channel and ideal leverage created by more profound and remote positioning away from the pivot point. Provide up to 40 percent higher efficiency than conventional tunnels.

 

 

 

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.
