Side-Power General Features:

  • Built for outstanding performance, you can rely on your Side-Power bow thruster or stern thruster year after year
  • Boat builders all over the world are choosing Side-Power for reliability, ease of installation and unrivalled safety features
  • This commitment to quality has made the new range of Side-Power thrusters manufactured by Sleipner Motor the market leader
  • Performance
    • The high performance of a Side-Power thruster is a result of their continuous efforts in product development and testing. propulsion technology know-how 5 bladed composite propellers purpose-built high power electric motors improved water flow from streamlined gearhouse design
  • Safety:
    • Side-Power thrusters include several features to ensure the safety of your boat and its passengers
    • These features protect against technical and operator errors
    • No overheating of electric motor
    • Mechanical protection of drive gear
    • Electronic protection against sudden change of drive direction
    • No accidental operation from child safe on/off and automatic deactivation
    • IPC comes standard on all DC electric thrusters hence reducing solenoid wear and the risk of lock in
  • Reliability:
    • The quality of a Side-Power thruster is always one step ahead
    • In house manufacturing and assembly
    • Engineering through experience
    • Use of superior materials
    • Controlled quality of every supplied part
    • 2-Year limited warranty
  • Installation
    • Through their extensive experience and close co-operation with major boat builders we know how important a correct installation is for the thruster system
    • Therefore they have made all the preparations to ensure that it is easy to install a Side-Power correctly
    • Compact-sized units
    • "Plug and Go" Electric wiring
    • Easily accessible battery cable terminals
    • Fast and safe propeller mounting with locknut
    • Professional and solid GRP stern thruster kits
    • Easy access zinc anodes

The Speed Controlled Thrusters (SEP Series) Features:

  • The SEP series are basically SE thrusters with the addition of the DC Power control system
  • Providing even more accurate control by fully regulating the power of the thruster as well as providing even longer run times, this is the latest in DC electric thrusters
  • The noise reduction and automatic "Hold" function are further benefits provided by the SEP series
  • Powerful single speed thrusters can, in light weather conditions, be a bit difficult to use as they push the boat too fast
  • The solution is to fit the new Sidepower DC Power Controller which enables proportional speed control of a DC electric thruster
  • By also controlling the thruster's power, you get even more precise handling of the boat in all conditions
  • Another great advantage is that when you run the thruster at less than full power, the usable run time is extended, with close to continuous usage being possible when you are running the thruster at less than 50% of full power (percentage of thrust with continuous duty depending on thruster model)

Ignition Protected Features:

  • High safety standards provide reliable and safe thruster installations in more boats
  • Side-Power offers modified versions of their DC electric thrusters in watertight housings for use in stern and other locations that may get wet or be exposed to petrol fumes
  • These thrusters are fully ignition protected (ISO 8846) for use in boats with petrol engines
  • They have a hermetically sealed composite housing around all electric parts
  • This provides the ignition protection as no petrol 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
  • Certified to ISO 8846 Ignition Protected standards
  • Water Proof (not for submerged mounting)
  • Stainless cable seals
  • Manufactured, tested and delivered as a ready sealed unit, ensuring that the installer does not have to fit any other parts that can jeopardize the hermetical seal
  • Supplied with 1 m/3.28' main power cables and termination blocks for easy and safe installation
  • Supplied with 1 m/3.28' plug and go control cable
  • Ignition protected housing can be opened and thereby retains serviceability of components inside the enclosure
  • Available as SEP-IP versions with DC Speed Control

SEP40/125S-1IP Features:

  • The SEP40/125S-1IP is a Proportional Speed Control DC Thruster
    • Side-Power's range of proportional speed control DC thrusters allow you to select the power you need for precise boat movements in any weather and sea conditions
  • The unique "hold" feature allows you to keep the boat in position at dock or in locks
  • This IP version is for use in gasoline engine boats or in applications where the splash proof/humidity proof motor enclosure is preferred
