Side-Power SE80/185T-12IP Thruster (Sealed Gearleg) with IP Housing, 12V, ignition protected, 185mm

The SE80/185T-IP suits a wide range of boats around the 12m/40ft mark and is thereby a very popular model. Utilizing the same mechanical parts as the even more powerful SE100/185T-IP, the reduced power makes it an exceptionally energy efficient thruster demanding less from the electric installation as well as being a very cost efficient model with a compact installation size. The SE80/185T-IP includes all the important and unique Side-Power features and qualities


Thrust @ 10.5VDC 176 lbs (80 kg)
Thrust @ 12VDC 212 lbs (96 kg)
Typical Boat Size 35-48' (10-15 m)
Tunnel Diameter (I.D.) 7.3" (185 mm)
Recommended Fuse Size 400 Amps (SMANL400)
Power @ 10.5V 6 hp (4.4 kw)
Fuse Size 400 Amp
Minimum Battery Capacity 1045 CCA SAE
Approximate Ship Weight (lbs) 61



To provide reliable and safe thruster installations in more boats, we offer modified versions of our DC electric thrusters in watertight 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 also covered and protected, making these thrusters the ideal choice for other stern thruster installations where it is difficult to ensure that the thruster will always remain dry.

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 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 Sealed Drive

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 Twin Propellers

Twin Propellers

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.


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.


Other items to consider when purchasing a new thruster:

  • Bow Tunnel or Stern Tunnel
  • Control Panels and Remote Controls
  • AutoMainswitch, Battery Disconnect, Fuse & Fuseholder
  • 4-Wire Harnesses (when not using AutoMainswitch)
  • 5-Wire Harnesses (for use with AutoMainswitch)
