E-series Bow and Stern Thrusters

The first step in Sleipner's eVision has been to develop the first-ever electric motor designed particularly for marine thruster use. After years of hard work, we have created these highly efficient, compact and lightweight electric motors rivaling the most cutting-edge machines used in the automotive industry today. When combining our new, state-of-the-art electric motor with the proven Sleipner gearleg design and Q-Prop™ skew propeller, you get a thruster that delivers performance and runtime never seen before in a DC thruster. The result is the new E-series of thrusters.

 

The E-series comes with the proven quality and performance of Sleipner’s gearleg and propeller design. Sleipner has optimized their design through more than 300,000 thrusters delivered over the last 40 years. Previous Sleipner thruster models can be upgraded with the new E-series electric motor either directly or by utilizing an adapter plate between the bracket and motor.

Product Features

DC

Powered by direct current.

                                                                                                 

IGNITION PROTECTION

IGNITION PROTECTION

Our ignition-protected products are compliant with ISO 8846 and ensure gasoline or other flammable fumes cannot enter or be ignited.

FLEXIBLE COUPLING

FLEXIBLE COUPLING

Flexible coupling protects the product’s driveline by compensating for misalignment between the shafts of the electric motor and gearleg.

 

GALVANIC SEPARATION

GALVANIC SEPARATION

Immersed parts exposed to seawater are galvanic isolated from the onboard electrical system, eliminating stray currents.

OVERHEAT PROTECTION

OVERHEAT PROTECTION

When an unsafe temperature is detected, On/Off thrusters are automatically shut-off to prevent overheating. Speed controlled thrusters provide extended run-time by derating the thrust power to maintain temperature within safe levels. 

 

SEALED DRIVE LUBRICATION

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.  

S-LINK™

S-LINK™

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
 

TWIN COUNTER-ROTATING PROPELLERS

TWIN COUNTER-ROTATING PROPELLERS

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.

PRO™

PRO™

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 integration.​

 

Q-PROP™

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
