Sleipner E250 eVision tunnel bow/stern thruster 24V

The E250 is a highly efficient, compact, lightweight thruster suitable for boats between 22-30 meters.

SKU: E250/300TC
Boat length
22 - 30 m

The E250 is a highly efficient, compact, lightweight thruster suitable for boats between 22-30 meters (72-100 feet). The integrated inverter for variable speed control makes for a quick and easy installation.

E250 has the new 6-phase PMSM synchronous motor made explicitly for marine thruster use, delivering performance and runtime never seen before in a DC thruster.

  • Up to 50% lighter
  • Compact design
  • Industry-leading runtime
  • Active air cooling
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
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
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.

The system also includes a practical hold-function. In a dual system (bow and stern) a single press of a button will keep you alongside the docks - making docking truly a one-person job.

Speed controlled thrusters are the best choice for joystick interaction.​
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.
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.
Sleipner offers installation flexibility to work with the space you have. Our thruster models allow installation at any angle on the tunnel, tailored to fit any space available in your vessel.
This product is manufactured for installations in environments that may experience moist or occasional splashes.
Power Supply
Powered by direct current.
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.
Flexible coupling protects the product’s driveline by compensating for misalignment between the shafts of the electric motor and gearleg.
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. Manufacturer product page for 24V Manufacturer product page for 48V
