NEW SX MODELS PRO
The next generation of external thrusters with proportional control
The brand new SX series is the world's most compact external bow and stern thrusters, offering several additional benefits for boat builders and retrofit installations. Its versatile installation possibilities and small size make it a perfect choice for vessels where the inside configuration does not allow a standard thruster installation. Available in 35 and 50 kg thrust as on/off and PRO-versions suitable for boats up to 11 meters / 37 feet.
The Side-Power engineering team has accumulated a vast amount of know-how about externally mounted thrusters over the years, resulting in a brand new generation of external trusters. The new generation of the SX series has improvements in virtually every component and is engineered for a more effective manufacturing process to reduce production cost and thereby price.
As a stern thruster, the design of the SX is the most compact ever created. If you could not fit a stern thruster before, the SX might be the right thruster for you.
Proportional Control
A DC Speed Control system allows for more precise handling of the boat in all weather conditions, applying only the necessary power needed. By limiting the power under normal weather conditions, noise levels are significantly reduced. The system also includes a practical HOLD-function in a twin thruster system. With a single press of a button, the bow and stern thruster keep you alongside the docks, making docking on your own very easy.
A DC Speed Control system consists of a proportional control panel, a power control unit, and a DC electric thruster, all tied together with the S-link™ control system.
Key design features
- Ease of installation with no GRP work necessary
- Energy-efficient and long run times
- Versatile installation that fits many hull shapes
- Patented Intelligent Power Control (IPC) protection as standard
Benefits
The world's most compact external thrusterUltra compact
Fits where others won't.
Quick and easy installation
Only requires drilling of three small holes with a minimal footprint on the hull. No fiberglass work is necessary. Compatible with standard Side-Power products, control panels, and accessories.
Versatile installation
The new SX models design allows for an extensive range of different installations as bow and stern thruster for motorboats and sailboats.
Long run times
The external placement of the unit provides a more efficient water cooling and allows a prolonged duration per cycle of the unit than with traditional bow and stern thrusters. Even longer run times in PRO version when running at reduced speed.
Optimal efficiency
The optimum efficiency of the SX models is the result of a shorter transverse channel and ideal leverage created by more profound and remote positioning, away from the pivot point. Provide up to 40 percent higher efficiency than conventional tunnels.
Safety
Ignition protected. Can advantageously be installed in stern locations/ on high octane fuel gasoline boats due to a hermetically sealed housing. ISO 8846 and UL 1500 certified. Galvanic isolation kit for metal/aluminium hulls and safety protection grids available as accessories.
Intelligent Power Control
Delivered standard with Side-Power's patented IPC:
- Provides delay between drive directions
- Monitors solenoid functions to reduce the chance of solenoid lock-in
- Will stop the thruster in case of a locked-in solenoid, without further user action and without controlling the main switch.
Quiet
With a short and optimally designed tunnel, vibration absorbing sleeves on all hull connections, 5-bladed Q-prop™, and the fully submerged unit, the thruster operates remarkably quiet.
Configurations
The new SX models are available in four configurations that allow a vast array of installation options with 35 or 50 kg of actual thrust at 10,5 volts.Standard stern thruster
The most compact stern thruster on the market. Minimal height and width requirements.

Stern thruster with propeller protection grids
An optimal solution for increased safety during watersport activities, or for vessels used in waters with debris or drifting objects.

Stern thruster with cowls
Many vessels have a hull design requirement on the transom of the boat that might disturb the water flow to and from a stern thruster, thus making it less efficient. With the adjustable cowls, water flow can be directed to be less disturbed, obtaining a higher level of efficiency or allow for a very shallow installation closer to the waterline.

In-flow configuration as bow or stern thruster
By adding the Hydropod Low-Drag Cover, the new XS-models can be mounted under the hull in the water flow for low- and mid-speed vessels. The optimal design adds minimal drag and will, in most installations, not be noticeable. The in-flow configuration is perfect for boats where it is difficult to fit a tunnel thruster or, for example, as a stern thruster for cruising sailboats.

SX Series Accessories
Extender/Galvanic Isolation
- Polyurethane spacer allows for easier installation in proximity to stepped and concave surfaces on the transom
- Spacer functions as galvanic isolation for metal hulls
SX Controller
- Side-Power IPC system
- Easy installation
- Easy mounting
- Little space requirements through compact measurements
- Enclosure in rugged flame-retardant ABS material
- For on/off and PRO-models.
Additional PPC, S-link cables and panel needed for PRO-models. Own seperate controller box available for each model
Cowls
- Made of reinforced UV resistant composite material
- Easy installation and retrofit
- Removes cavitation on shallow installations (more thrust, less noise)
- Guides thrust away from flaps or stern drive
- Either preassembled from the factory or as a retrofit kit
Safety Protection Grids
- Hydrodynamic shape to reduce resistance
- Made of reinforced UV resistant composite material
- Removable for cleaning and propeller service
- Either preassembled from the factory or as a retrofit kit
Hydropod Low-Drag Cover
By adding the Hydropod Low-Drag Cover, the new SX models can be mounted under the hull in the water flow for low- and mid-speed vessels. The optimal design adds minimal drag and will, in most installations, not be noticeable. For a typical sailboat cruising at 7,5 knots, the added drag is less than 5 kg. The in-flow configuration is perfect for boats where it is difficult to fit a tunnel thruster or, for example, as a stern thruster for cruising sailboats.
