To help you make your decision on which bow thruster is best for you, we have created a key to these special features, so that you can read in more detail about the benefits they provide.
The new 5-blade special skew propellers are the result of 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 has been achieved, and we have even made them a little more aggressive on some models, increasing the thrust on some thrusters about 5%. Please see individual information on each new thruster for more details.
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.
To provide reliable and safe thruster installations in more boats, Side-Power offer modified versions of their DC electric thrusters in water-tight housings for use in stern and other locations that may get wet or be exposed to gasoline fumes. These thrusters are fully ignition protected (ISO 8846) for use in boats with gasoline engines. They have a hermetically sealed composite housing around all electric parts. This provides the ignition protection as no gasoline fumes can enter and be ignited by sparks.
The other advantage is that the electric parts that could be damaged by water are covered and protected, making these thrusters the ideal choice for thruster installations where it is difficult to ensure that the equipment will always remain dry.
The Side Power unique thruster controller that intelligently protects the thruster from potential inherent problems in all high current applications as well as user faults. It includes several important safety features imperative in a product with such high power, run by DC electrics, as a thruster.
Sealed gearleg with long-life “mechanical” seal where highly polished ceramic and carbon surfaces form the only moving sealing surfaces, ensuring protection against water damage in 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
The gearhouse / drive legs of most Side-Power DC Electric thrusters are now fully galvanically isolatedfrom the electric motor and motor bracket. This ensures that even if there is an accidental short circuit or a current leak for other reasons, the immersed parts are not effected as they could be with direct electric contact.
A properly engineered single propeller system will be the most energy efficient thruster. Its compact design fits easily into narrow bows making it the perfect match for our smaller models. With more than 60.000 single propeller thrusters in use, the Sidepower single series system has proven its reliability.
The twin propeller system can give more thrust than a single propeller system in the same tunnel diameter. This is our choice for our mid-range models where high thrust is required in a small tunnel diameter. Due to the compact design and high performance, the twin models have become the thrusters of choice among boat builders around the world.
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.
S-Link ™ is a CAN- based system with intelligent communication between all connected devices, much like a computer network. S-Link digital signal transfer is used on all SR (foldable) and SEP (power-controlled) models.
