The E300 48V E-series Thruster is a marine electric propulsor with 300 kg of thrust. Compatible with tunnels of 300 mm (11.81″) in diameter, it enhances maneuverability and navigation in various vessels, providing a powerful and efficient solution.

The E300 is a highly efficient, compact, lightweight thruster suitable for boats between 72-100 feet. The integrated inverter for variable speed control makes for a quick and easy installation.

E300 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.



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.


Powered by direct current.


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


This product is manufactured for installations in environments that may experience moist or occasional splashes.


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.


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.

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.?


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


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.


Twin propellers can provide more thrust than a single propeller system in the same tunnel diameter. We use this system in our mid-range models, where high thrust is required in small tunnel diameters. Due to the compact design and high performance, the twin models have become the thrusters of choice among boatbuilders worldwide.


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.
