Sleipner Side-Power Thruster Systems

AMI are the Exclusive Distributor for Sleipner Side-Power Systems throughout Australia and Singapore.

Manufactured by Sleipner Motor, Norway, Sleipner Side-Power offer over 120 models of thruster for vessels ranging from 30 to 100’. The range includes DC Thrusters, Retractable thrusters, Electric AC and Hydraulic models to suit a range of vessels and configurations.

Various upgrades exist to make boating even more comfortable, such as DC Proportional, an upgrade kit that allows users to take ultimate control during docking with the unique ‘hold’ function on their remote.

Sleipner Side-Power Thrusters offer the following features:

Noise Reduction

  • Noise reductions of up to 75% measured in controlled environments
  • The expected and tested normal noise reduction in "average installations" 20-40%
  • Upgrade kits are available for most “SP” series thrusters with special adaptors

Intelligent Power Control

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

Gravity Feed Lubrication

The thruster gear leg 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.

  • Separate oil reservoir placed above the waterline.
  • Allows easy access for oil changes
  • Having the advantage to be able to change oil in units used commercially, with hundreds of running hours per year

Sealed Drive Lifetime Lubricated

Sealed gear leg 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

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 eliability.

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 equired 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.

Twin Counter Rotating 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.

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.

Ignition Protected

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. Theyhave 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.


S-link is a "CAN" based control system with full intelligent communication between all units in the system, much like a computer network. Main advantages include:
- Round, compact and waterproof plugs with unique keying and color coding to avoid faulty hookup
- Unlimited number of commands or information transfer on a single cable
- User feedback at panel - Intelligent troubleshooting.

DC Speed Control

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 Sleipner Side-Power for many years. All 12 & 24 volt DC electric thrusters produced by Sleipner Side-Power can be enabled for DC Speed Control by authorized Sleipner Side-Power service personnel, even the oldest models.

Sleipner Side-Power DC Thrusters

The standard bow and stern thruster series are the base for all our extensive range of DC electric thrusters.
They are fitted in a tunnel through the bow, or into Sleipner Side-power's stern tunnels to use as stern thrusters. The electric motors, solenoids, patented IPC control system and the mechanical parts of the propulsion system are all totally custom designed and built, utilizing the extensive experience gained through years of leadership in the global thruster market.

Speed-Control Upgrade to Proportional Control – Docking made easy
Have you edged your vessel around a crowded marina, or had to feather the power of the thruster in low speed maneuvers, and thought there should be an easier way?


Sleipner Side-Power DC Proportional Thrusters offer a balance of high performance with the control required for precision movement. Comprised of three main elements, the proportional control panel, power control unit, and DC Thruster, the Sleipner Side-Power Proportional Thruster system offers boaters full control, even in rough conditions.

Available as an upgrade to a standard Sleipner Side-Power DC Thruster, or as a new standalone system, Proportional Thrusters are not only highly efficient, but by not requiring continuous full power, the usable run time is only limited to the capability of the battery in some cases.

Unique to the Proportional control panel, the 'Hold' function synchronizes both bow and stern thrusters with the push of a button, keeping the vessel parallel to the dock, while the level of thrust is adjusted accordingly. Docking just got easier.

Normally this level of control would be limited to an expensive hydraulic or AC thruster system, not always an option where usable space is at a premium. The Proportional Thruster is a considerably more compact, and cost effective alternative.


Sleipner Side-Power DC Thrusters - EX Series

EX Series:
The EX series can be installed in most types of boats between 6 and 15 meters independently of hull form, hull material, propulsion and depth. These pod thrusters are an excellent choice where a tunnel thruster cannot be fitted, or as an extremely compact stern thruster. As they are easy to fit they are especially good for retrofitting.

Sleipner Side-Power DC Thrusters - SR Series

SR Series:
For boats that cannot fit a tunnel thruster or do not wish to have an external thruster under the boat, then a retractable thruster is the solution. Sleipner Side-Power have designed a product range that is focused on practical sturdiness, uncompromised safety and quick deployment.

Sleipner Side-Power DC Thrusters - SX Series

SX Series:
Sleipner Side-Power now offers a complete external stern thruster assembly, specially designed for installation on boats with twin stern drives.

Sleipner Side-Power Thrusters for Larger Vessels

AC Electric
Safe to operate and trouble free to install, Sleipner Side-Power Electric AC Thrusters range from 240-1200KG of continuous thrust.AC Thrusters are suited to multiple configurations, and can be combined with hydraulic thrusters and existing setups. Contact your AMI representative for more information on Sleipner Side-Powers range of Electric AC Thrusters.

Hydraulic thruster systems are the natural choice when extensive thruster usage or long run cycles are required. Sleipner Side-Power design their hydraulic systems with the style needed for pleasure craft and the reliability necessary for commercial use. Ask your AMI representative for more information about the Hydraulic Thruster range.
