Bow thruster 25.0 tunnelset

The Bow Thruster Tunnel Set 25.0 from Rim Drive Technology is a particularly powerful electric bow thruster system with 96V operating voltage and 25.0 kW power. With an impressive static thrust of 320 kgf, the system is ideal for large boats, yachts, and professional maritime applications where maximum control and reliable performance are crucial.
Thanks to the integrated tunnel construction, optimal water flow is achieved, enabling precise maneuvers even in strong winds or currents. The tunnel with a diameter of 355.6 mm ensures stable integration into the ship's hull and reliably protects the drive even under challenging conditions.

The IP68 protection class makes the motor completely waterproof and saltwater-resistant. The integrated motor control ensures efficient and precise regulation of the drive, while the robust stainless steel construction provides long service life and high durability in maritime use.

Our standard bow thruster is the quietest in its class. Thanks to its compact design, it can be installed further forward in the bow, which allows for better control – especially in wind or current.

This electric bow motor can also be used as a stern thruster. It is designed for continuous operation and does not require wear-prone components such as shaft seals or gaskets.

This ensures a reliable, low-maintenance, and particularly quiet propulsion system.

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.
