The SEP25 is a compact thruster with variable speed control designed to fit a tunnel of only Ø100 mm. SEP25 is suitable for vessels less than 7m depending on the vessel's windage area. Only available for bow installation.

As with all the other thruster models in Sleipner's tunnel series, the SE25 offers tremendous installation flexibility, as it can be installed upon the tunnel at any angle and the thruster motor can be rotated on the motor bracket in 90 degrees steps.

The SE25 is galvanic insulated and features Sleipner's patented IPC technology for intelligent power control and safety. See more of the product features below.
Powered by direct current.
Automatic detection of overheating of internal components. When an unsafe temperature is detected, the unit is automatically shut off to prevent overheating.
S-Link™ is a CAN-based control system used for communication between Sleipner products installed on a vessel.
  • Compact and waterproof plugs
  • Keyed and color-coded connectors to ensure correct and easy installation
  • Different cable lengths, extenders and T-connectors makes the system scalable and flexible to install
A PRO™ thruster system enables you to apply only the necessary power to complete your maneuver. The variable speed control eliminates the noise associated with standard on/off thrusters.

With a dual setup (bow and stern), you also get a practical hold function enabling you to set and leave the level of thrust.

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.
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.
