Side-Power PROportional


A DC Speed Control system contains three main elements - proportional control panels, a power control unit and a DC electric thruster - all tied together with the new S-link™ control system. The thrusters used in a speed control system are almost identical to the familiar SE range of DC thrusters, the only difference being the addition of a temperature sensor and a new electronic control box. All mechanical and main electric parts are from the well proven thruster range produced by Side-Power for many years.

All 12 & 24 volt DC electric thrusters produced by Side-Power can be enabled for DC Speed Control by authorized Side-Power service personnel, even the oldest models.

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 Q-prop™


The new 5 blade special skew propellers are the result of over 2 years of development work and thousands of tests. They have been designed to reduce the noise level, while maintaining the exceptional efficiency of the old 4 blade Side-Power propellers. This goal was achieved, and we even chose to make them a little bit more aggressive on some models, increasing the thrust on some thrusters about 5%. Please see individual information on each new thruster for more details.

  • Noise reductions of up to 75% measured in controlled environments
  • The expected and tested normal noise reduction in average installations: 20-40%
  • Will be delivered on all Side-Power models except models with 300mm and 385mm tunnel diameter
  • Upgrade kits are available for most SP series thrusters with special adaptors

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
