SEP60 Tunnel thruster, 12v

SEP60 Tunnel thruster, 12v
60kg thrust proportional

With its outstanding energy efficiency and unrivalled reliability, the SE60/185S is the classic and best selling thruster in the Side-Power series and includes all the important and unique Side-Power features and qualities - why settle for less.

Side-Power Intelligent Power Control

Intelligent Power Control

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.

  • Provides delay between drive directions
  • Monitors solenoid functions to reduce the chance of solenoid lock-in
  • Will stop the thruster in case of a lockedin solenoid, without extra user action and even without controlling a main switch.

Side-Power Single Propeller

Single Propeller

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 Side-Power single series system has proven its reliability.

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 Galvanic Separation

Galvanic Separation

The gearhouse / drive legs of most Side-Power DC Electric thrusters are now fully galvanically isolated / separated from 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.

  • Achieved by composite bushings around the bolts and beneath the washers and a bushing in the motor bracket electrically isolating the drive housing from the motor bracket.
  • Available on DC electric models with flexible couplers only, where the flexible coupler provides galvanic separation of the motor and gearleg shaft.

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 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 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.

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.

* All Side-Power thrusters gets their thrust rating from the actual performance you can expect in a boat - at the voltage a normal installation will provide at the thruster. We have choosen to use the net performance at 10.5V/21V, but we also list the effect at 12/24V for comparison.

** All battery CCA ratings are stated with the DIN rating, multiply by 1.9 to to get the SAE equivalent (at 0°F, ABYC standard).
