Bow thruster 2.5 tunnel set

The Bow Thruster Tunnel Set 2.5 kW from Rim Drive Technology is a powerful electric bow thruster with 24V operating voltage and 2.5 kW power. Despite its compact design, it delivers a static thrust of 23 kgf and is ideal for small to medium-sized boats as well as demanding maritime applications.

Thanks to the integrated tunnel construction, the drive is optimally protected and can be cleanly and stably integrated into the hull of the ship. The tunnel with a diameter of 114.3 mm ensures efficient water flow and high maneuverability even under difficult conditions.

The Thruster Tunnel Set from Rim Drive Technology contains all the necessary components for the professional installation of a bow or stern thruster. It is optimally matched to the respective drive systems and ensures efficient water flow as well as maximum thrust.

Thanks to its robust and saltwater-resistant construction, the set is ideal for maritime use. The precisely manufactured components allow for easy integration into different boat hulls and guarantee a durable, reliable solution for demanding applications.

A bow thruster – in German, Bugstrahlruder – is a transverse thruster located at the front of a boat. It generates lateral thrust and allows the bow (the front of the boat) to be moved precisely to the left or right. This is especially helpful when:


✔ Docking in the harbor
✔ Casting off in crosswinds
✔ Maneuvering in tight marinas
✔ Positioning in currents

The bow thrusters from Rim Drive Technology are suitable for boats from 2 to 20 meters and are available in power levels from 0.5 to 75 kW. Thanks to their modular design, they can be easily expanded or converted for other purposes. This way, you remain flexible in the future as well.

All our electric bow thrusters are saltwater-resistant, compact, and lightweight. They contain neither oil nor seals, which prevents leaks and significantly reduces maintenance requirements.
The unique rim-drive technology operates with only a single rotating component. This minimizes the risk of failure while maximizing performance.

Our motors offer proportional control and instant acceleration for precise and controlled maneuvers.

Also as a stern thruster A major advantage of our electric bow motors is their versatility. You can install them not only at the bow of the boat, but also at the stern as a stern thruster.


This makes maneuvering easier, especially when docking or navigating in tight areas. This way, you maintain full control over your vehicle in every situation.
