Product details
This compact and practical SX series bow and stern thruster from SIDE-POWER is externally mountable and ideally suitable for boats where a tunnel bow thruster cannot be installed, regardless of the hull shape, material and propulsion system.
The SX models can be used in all types of boats, from sailboats and motorboats to catamarans with steel, aluminium, wood or GRP hulls.
As the external bow thruster is installed further forward towards the bow compared to a conventional tunnel bow thruster and has a significantly lower installation position, a much better leverage effect is achieved. This means that the EX series bow thrusters can move considerably larger boats with a lower nominal power.
Features
Hydrodynamic design
Very short cross channel and ideal positioning reduce water resistance compared to conventional systems. Loss of speed is not noticeable.
Easy installation
Only the installation holes are required, which are sealed with special rubber gaskets. No laminating necessary.
Noise reducing
External design results in significant noise reduction. Deeper installation position for minimal cavitation.
Longer operating times
The external mounting position under the hull allows efficient cooling. This results in considerably longer operating times than with conventional systems.
Space-saving installation
The external construction of the unit saves a lot of space on board compared to conventional systems.
Optimum efficiency
The significantly shorter cross tunnel and ideal leverage effect due to the deeper installation position, further away from the pivot point, result in optimum efficiency. This enables an increase in efficiency of up to 40% compared to conventional systems.
Quality
All components of the SX series are carefully constructed coordinated so that the systems meet the highest quality requirements. Manufactured in our ISO-certified factory in Fredrikstad.
i-BOX - Intelligent system control
Delivery includes the i-Box control unit and the SX35S bow and stern thruster.

i-BOX - Intelligent system control
- Minimum electronic switching delay in case of abrupt change of thrust direction
- Permanent monitoring of the relay function
- Automatic deactivation of the bow thruster in case of a malfunction of the relay, additional actuation of the main switch is not necessary
- Compatibility with all Side-Power bow and stern thrusters is guaranteed by using standard Side-Power components.
Delivery includes the i-Box control unit and the SX35S bow and stern thruster.
