Side-Power (Sleipner) Stern Thrusters - SX50 12V 110.2 lbf (50.0 kgf) 150mm Hull

The SX50 is Side-Power (Sleipner)'s most compact thruster yet. Its versatile design allows for installation on boats of any hull shape up to 37 feet, providing 35 kg of thrust.

• Energy-efficient and long run times.
• Easy to mount, with no GRP work necessary.
• Intelligent Power Control.

SX50 is also available in PRO with variable speed control.

DC ELECTRICAL CURRENT
Powered by direct current

ANALOG
Side-Power (Sleipner) analog signal cables with plug-and-go connectors are color-coded to match the wiring diagrams with high-quality connectors to ensure a correct installation.

OVERHEAT PROTECTION
Detect when internal components become too hot. When an unsafe temperature is detected, the switch automatically shuts off the unit to prevent overheating.

IGNITION PROTECTION
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.

GALVANIC SEPARATION
The gear house and drive legs are 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 affected 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.

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 Side-Power (Sleipner) single series system has proven its reliability.

Q-PROP™
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 Side-Power (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 Side-Power (Sleipner) models except models with 300 mm and 385 mm tunnel diameter.
• Upgrade kits are available for most SP series thrusters with special adaptors

INTELLIGENT POWER CONTROL
The Side-Power (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.
