The SCHOTTEL Electric Propulsor (SEP) and the Siemens-SCHOTTEL Propulsor (SSP) are innovative propulsion systems which differ mainly in the kind of electric motors housed in the pods.
The two pillars of the SSP – a joint development of Siemens and SCHOTTEL – are the SCHOTTEL Twin Propeller technology and a permanently-excited motor (PEM) from Siemens characterised by its high efficiency and slim-line construction.
With the SEP SCHOTTEL offers a propulsion system with asynchronous or synchronous motors depending on the owner/shipyard request and application of the vessel.

The popular 55S thruster offers the power and performance needed on most yachts from 29-38 ft loa. It features a maintenance-free, sealed gearleg for easy installation and a powerful purpose-built electric motor. Like all Side-Power thusters, the 55S2i features the patented Intelligent Power Control (IPC) for safe, reliable performance.

|
|
The ultra-compact 30S thruster offers the 60-85 lbs. of thrust in a package small enough to fit in boats as small as 20' loa. A sealed gearleg, high-performance prop and easy-access zincs make it a powerful and easy-to-maintain addition to any boat.

|
The 40S thruster gets every ounce of power you could want out of a 5" tunnel thruster. Side-Power's proprietary IPC system ensures safety and reliability while maintain high thrust output and low-noise operation. Customize your thruster system with our wide range of controls, remotes and other add-ons.

TRAC Thrusters deliver more thrust per horsepower than any other thruster available. TRAC's twin counter-rotating propellers are more efficient and can reach higher horsepower than single prop thrusters.
TRAC hydraulic thrusters are fitted with high efficiency piston motors. 8" thru 12" thrusters are available in a DC version and all TRAC thrusters are available in AC versions.
Thruster control is available in single or proportional speed. TRAC proportional thruster control enables precise maneuvering control.

Installing an electric bow or stern thruster in a petrol (gasoline) engined boat can be very dangerous, due to the possibility of the electric motor igniting fuel vapour.
In order to eliminate the risk, this special housing will shield the bow or stern thruster from potentially explosive vapour. The housing enables the thruster to comply with the ISO 8846 Marine "ignition protection" standard. In addition to the standard thruster, the set consists of a watertight (IP65) housing for the electric motor and relays, together with all required seals, electrical connectors and fastening components. An automatic fuse for the control loom is also supplied. This can be reset externally without opening the housing.

Swing retracting thrusters are ideal for higher performance sailing yachts, and fast planing or semi-displacement hulls. With the thruster in a raised position it offers a completely fair hull section causing minimum drag. Lewmar has now introduced a completely new and simple design, which is a logical step forward from the current successful range.
This design is in keeping with Lewmar's environmental concerns and has no hydraulic motors or hoses in the water. Unlike many manufacturers, all of this componentry is housed inside the hull, preventing pollution in the event of an oil leak.

The most compact thrusters available and ideal for boats where space is limited are the Compact series. Due to the innovative design they offer outstanding performance in a very compact envelope. They feature a belt transmission between motor and drive, which further reduces noise level and hence motor wear.

Installed in combination with a bow thruster the stern thruster improves boat manoeuvrability and greatly simplifies berthing, even with larger boats. QL stern thrusters are recommended for boats with inboard engines, (single installation) with a conventional propeller shaft. They are installed at the stern, with the motor inside the hull and the propeller tunnel outside the transom. The tunnel has a flared inlet and outlet in order to improve flow.

WESMAR's innovative Double Thrust bow thrusters provide a conservative 40% more thrust than conventional single-prop designs with the same tube, prop size, GPM and PSI. When water passes through a spinning prop two types of energy are created: axial and swirl. WESMAR's VORTEX systems convert swirl energy into axial energy. The result is greater efficiency and more thrust

Prop-eye
Is an extremely silent and powertul high-performance propeller with internal ring motor for short and continuous operation.
Thus it is usable as a drive unit or as bow- and stern thrusters.
Topic energy savings
Skippers know the situation:
Out of consideration for nature and for smaller boats there are usually speed limitations on fairways, rivers, channels or inland waters. Here the use of the main engine is not economic and it is designed for much higher speeds. Additionally there's the noise that one feels disturbing.
With Prop-eye you can switch off the main engine and cruise almost silently by using the much more quiet and energy saving generator as the main energy source.
Prop-eye 265
The Prop-eye 265 is powered by three phase current.
With its 130 kp thrust it is an ideal drive system for silent and economic propulsion for example for cruising rivers or near the shore - without using the main engine.
Special features
- Robust
- No cavitation
- Longevity
- High efficiency
- Very low weight
- Low power consumption
- Compact, small assembly dimensions
- Smooth running device by axial guided propeller
- Very quiet and additionally acoustically decoupled from the hull
- Suitable especially on boats with little space available
Use as 3 phase current drive
- Powered directly by the generator
- Electronically controlled
- Stepless regulation of the rotation speed
- No galvanic corrosion
- Motor without spark formation (no contacts)
- Use of thin cables

Skippers know the situation:
Out of consideration for nature and for smaller boats there are usually speed limitations on fairways, rivers, channels or inland waters. Here the use of the main engine is not economic and it is designed for much higher speeds. Additionally there’s the noise that one feels disturbing.
With Prop-eye you can switch off the main engine and cruise almost silently by using the much more quiet and energy saving generator as the main energy source.
The Prop-eye 170 is powered by alternating current (ac). When using the battery the provided potential transformer changes the co-current flow (dc) into alternating current (ac). Naturally it can also be driven without potential transformer driven directly by a generator.
So the Prop-eye 170 with its 40 kp thrust is an ideal combination as bow and stern thrusters under usage of the battery or a generator, or as an auxiliary drive under usage of a generator.
Special features
- Robust and longevity
- No cavitation
- High efficiency
- Very low weight
- Low power consumption
- Compact, small assembly dimensions
- Smooth running device by axial guided propeller
- Available as AC or as DC version

- Suitable especially on boats with little space available

In sailing vessels where inadequate immersion is possible for traditional tunnel thrusters, retractable thrusters can offer a solution. These have been developed over 20 years and the range now extends up to 90 kW.
These thrusters are also available as a version where the unit can be rotated 90o for use as emergency propulsion.
