Side-Power Twin Counterrotating Propellers

Twin Counterrotating 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 Sealed Drive Lifetime Lubricated

Sealed and lifetime lubricated gearleg

Sealed gearleg with long-life "mechanical" seal where highly polished ceramic and carbon surfaces form the only moving sealing surfaces, ensuring protection against damaging water intrusion into the gear leg. Pre-filled with special gear oil for lifetime lubrication.

  • "Mechanical" seals with surfaces of ceramic and carbon for ultimate security against water intrusion

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
