5 Variants

Side-Power PROportional


A PROportional speed controlled thruster system allows for more precise handling of the boat in all conditions, applying only the necessary power needed to complete your maneuver confidently. 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 will keep you alongside the docks - making single handed docking very easy indeed! Proportional thrusters are also the best choice for joystick interaction.

Side-Power S-link™


S-link™ is a CAN-based control system with full intelligent communication between all units in the system, much like a computer network.

  • Round, compact and waterproof connectors with unique keying and color coding to avoid faulty hookup
  • Unlimited number of commands or information transferred on a single cable
  • User feedback at panel
  • Intelligent troubleshooting

Side-Power Twin Counter-Rotating

Twin Counter-Rotating Propellers

Two counter-rotating propellers can give the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in our larger thrusters for maximum power. The TC models are the favourite thrusters among leading boatbuilders for their high-end yachts.

Side-Power Gravity Feed Lubrication

External oil tank for easy access

The thruster gearleg is filled with oil from a remote reservoir located above the waterline. This generates overpressure, making an effective seal against water intrusion in the gear leg.

  • Separate oil reservoir placed above the waterline
  • Allows easy access for oil changes
  • Having the advantage to be able to change oil in units used commercially, with hundreds of running hours per year
