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 50 mm.
Remote control is a popular accessory. See some of the important product and safety features below.
Product Description
Properties
Q-PROP™
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
INTELLIGENT POWER CONTROL
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.
IGNITION PROTECTION
Ignition-protected products are compliant with ISO 8846 to operate safely in hazardous environments where gasoline vapors or other flammable gases might be present.
OVERHEAT PROTECTION
When high temperatures are detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating power to maintain temperature within safe levels.
ANALOG
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.
GALVANIC SEPARATION
Immersed parts exposed to seawater are galvanic isolated from the onboard electrical system, eliminating stray currents.
SEALED DRIVE LUBRICATION
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.
SINGLE PROPELLER
A properly engineered single propeller 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.
