Expert opinion

« Technical analysis of the Sleipner EX70C outboard thruster »

The Sleipner EX70C external thruster is a strategic solution for owners of 12–14m motorboats who cannot install a traditional tunnel thruster due to structural constraints or space limitations. Mounted at the stern on the transom, it eliminates the need for complex lamination work, significantly reducing installation time and cost. Securing with just three drilled holes, sealed with a specific sealant, is a major advantage for hull integrity.

The external design and water-cooled motor give the EX70C an advantage in continuous operating time and a drastic reduction in onboard noise perception—a critical comfort factor. While its 67 kg thrust is suited to its target, precise sizing must be validated for each vessel, including voltage and control accessories, justifying a quote-based purchase process. This model stands out for its marine-grade robustness and sealed-for-life lubrication system, minimizing maintenance.

It is ideal for retrofits or additions on existing boats without compromising interior space, offering improved maneuverability during docking and departures. It is essential to ensure compatibility with the boat’s electrical architecture and integrate the appropriate controls for optimal user experience.

Frequently Asked Questions

Need help? Contact us

Why is the Sleipner EX70C thruster only offered on a quote basis?

The Sleipner EX70C stern thruster is offered only on request. This approach ensures the system is correctly sized for your vessel, that the voltage is compatible with your electrical installation, and that the installation location and required accessories are validated by our experts. This guarantees optimal performance and enhanced safety of the installation.

What is the thrust power of the Sleipner EX70C thruster?

The Sleipner EX70C thruster delivers a nominal thrust of 70 kg at 24V. For maximum performance, it can reach a thrust of 95 kg at 24V.

What is the required power supply voltage for the EX70C thruster?

The Sleipner EX70C stern thruster requires a 24-volt power supply to operate correctly.

Is the EX70C thruster quiet in operation?

Yes, the Sleipner EX70C thruster is fitted with the Q-PROP™ propeller. This five-blade, skewed propeller is specifically designed to reduce operating noise by 20 to 40% under real-world conditions and up to 75% in controlled tests, while maintaining or improving thrust performance.

What are the main safety features integrated into the EX70C thruster?

The Sleipner EX70C thruster integrates several advanced safety features to protect the device and the user:

Intelligent power control: minimizes mechanical wear and monitors solenoid performance, cutting power if a solenoid seizes.Overheat protection: automatically detects high internal temperatures and shuts down the system before damage occurs.Galvanic isolation: all submerged parts are electrically isolated from the onboard system to eliminate stray currents and prevent galvanic corrosion.Secure startup: control panels require a two-button activation, preventing accidental starts.

For which type of sailboat is the EX70C thruster recommended?

The Sleipner EX70C stern external thruster is ideally suited for vessels measuring between 10 and 15 meters (approximately 35 to 48 feet).

Is it possible to have variable speed control with the EX70C thruster?

Yes, the EX70C thruster is compatible with Sleipner’s PRO™ Variable Speed Control system. This feature enables smooth, silent, and precise maneuvering via variable operating speed. It also includes a hold function for twin systems and is ideal for integration with a joystick.
