The SRL170 is a sturdy retractable thruster suitable for cruiser-racers or flat-bottomed boats between 15-22m. With its quick deployment and 170-210 kgs of thrust, you get a thruster installation you can rely on year after year.

The SRL170 is also available in PRO with variable speed control.

Powered by direct current.
Flexible coupling protects the product’s driveline by compensating for misalignment between the shafts of the electric motor and gearleg.
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.
Automatic detection of overheating of internal components. When an unsafe temperature is detected, the unit is automatically shut off to prevent overheating.
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.
Two counter-rotating propellers offer the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in our larger thrusters for maximum power. Our twin-counter thruster range is the favorite among leading boatbuilders in high-end yachts.
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.
