PRO™
A PRO™ thruster system enables you to apply only the necessary power to complete your maneuver. The variable speed control eliminates the noise associated with standard on/off thrusters.
The system also includes a practical hold-function. In a dual system (bow and stern) a single press of a button will keep you alongside the docks - making docking truly a one-person job.
Speed controlled thrusters are the best choice for joystick interaction. -
INTELLIGENT POWER CONTROL
Sleipner's patented intelligent power control provides a minimal delay between drive directions to reduce wear of the mechanical parts while monitoring solenoid functions. In the case of a solenoid lock-in, the thruster will automatically stop without extra user action or controlling the main switch.
-
OVERHEAT PROTECTION
When high temperatures are detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating power to maintain temperature within safe levels.
-
FLEXIBLE INSTALLATION
Sleipner offers installation flexibility to work with the space you have. Our thruster models allow installation at any angle on the tunnel, tailored to fit any space available in your vessel.
-

TWIN COUNTER-ROTATING PROPELLERS
Two counter-rotating propellers offer the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in our larger thrusters for maximum power. Our twin-counter thruster range is the favorite among leading boatbuilders in high-end yachts.
Item code: SEP210/250TC
SEP210 PRO™ with variable speed control is one of Sleipner's most popular models with 210-250 kg thrust. Suitable for boats between 55-78 feet, depending on weight and windage area. Can be mounted in the bow and stern.
The thruster offers great installation flexibility as it can be mounted at any angle on the tunnel. Additionally, the electric motor can be rotated 90 degrees on the motor bracket.
It is galvanically isolated and features Sleipner's patented IPC technology for intelligent power control and safety. See more of the product features below.
Sleipner's tunnel thrusters are the world's top-selling thrusters resulting from over 35 years of development. Over the years, our tunnel thrusters have been installed in over 350,000 boats worldwide.
Bow and stern thruster
They are fitted either in a tunnel through the boat's bow or into a stern tunnel at the boat's stern. Available as standard version (on/off), PRO™ version (variable speed control), and IP PRO™ version (with ignition protection and variable speed control), extending from 20 kg to 300 kg of thrust.
Sleipner's stern tunnels are designed with solid and durable fiberglass to enhance the thruster's performance and are installed effortlessly in the boat's transom. Additional cowls (sold separately) allow installation in boats with shallow drafts or obstructions on the stern.
The electric motors, solenoids, patented IPC control system, and mechanical parts of the propulsion system are all custom designed and built - utilizing the extensive experience gained through years of leadership in the global thruster market.
Docking has never been easier
Our PRO™ thruster models are equipped with speed control, giving you full variable control of the thruster. The speed control is more intuitive for you as a boater and makes for a quieter and more relaxed maneuver. If you install a dual thruster system (bow and stern), you get the revolutionary hold function, pinning the boat to the pier while docking.
Ignition protection
We offer ignition-protected thruster models to provide a reliable and safe installation in locations where the thruster motor may be exposed to water or gasoline fumes.
An additional advantage is that electric parts that could obtain water damage are also covered and protected, making these thrusters the ideal choice for stern thruster installations where ensuring that the thruster will always remain dry is difficult. The IP versions have all the benefits and proven reliability of our standard tunnel thrusters.

Not necessarily. These systems typically come with a Battery Management System (BMS) that will disconnect the thruster in case of any issue with the battery (for instance, if the thruster draws more current than the BMS allows). Just imagine a sudden cut-out in the middle of a maneuver without any pre-warning.
At Sleipner, we recommend a solution with a simple, separate battery and without a disconnect BMS system (such as the lead acid bank frequently used for starting or similar). The helmsman will then be warned when the battery is getting low and feel that the thrusters are gradually losing power, which is significantly better than losing your thrusters without any pre-warning.
Disclaimer: Ensure battery/energy source is installed according to CE/ISO current rules and regulations and by licensed electricians.
-
Yes, you can, but not without taking some precautions. Sleipner produces two product lines of thrusters that will work well with high-capacity batteries and one product line which should be used with caution in combination with LiFePO4, Lithium, Li-ion, or similar batteries, which may be capable of delivering higher voltage under load than traditional batteries (such as lead-acid, AGM, gel or similar).
- All Sleipner proportional thrusters will work well with Li-ion or LiFePO4 batteries, as the included PPC unit will control the output voltage to a safe level for the thruster. Make sure, though, that you actually get a good battery intended for maritime use. NB - make sure you have the latest embedded software installed.
- All Sleipner eVision thrusters have built-in functionality to limit the maximum voltage delivered to the thruster. Again, make sure your battery is intended for maritime use.
- Traditional DC on/off thrusters may be damaged or have a reduced life expectancy if operated at voltage levels outside their specifications.
Disclaimer: Ensure battery/energy source is installed according to CE/ISO current rules and regulations and by licensed electricians.

Yes. Most engineers would tell you that it is not ideal for connecting the bow thrusters to a service bank protected by a Battery Management System. Thrusters are heavy consumers, and they may create sudden peaks in current draw, which again may cause the BMS to disconnect the batteries if the thruster draws more current than allowed. If this happens in the middle of a maneuver, you would be left without thrusters and may lose control of the boat.
Hence, Sleipner recommends that the thrusters be connected to a separate battery bank (that is not lithium) without a Battery Management System that can disconnect the batteries (and consequently the thrusters).

This is a unique patented Sleipner safety feature supplied with all standard (on/off) DC electric Sleipner thrusters. The IPC functionality provides two unique features:
1) It will detect "flapping" of the solenoid (typically caused by badly charged batteries that are subject to a huge current draw and voltage drop when the thruster motor is engaged), and will stop trying to run the thruster, preventing excess solenoid contact tip wear and dramatically reducing the risk for a weld-in situation of the solenoid. A 'weld in' (run away) situation is when a thruster continues operating without a signal from the operator at the control panel.
2) Even if the solenoid has a weld-in situation, which even with the IPC prevention actions is still possible, as all mechanical switches can weld-in at a point, the unique IPC function will STOP THE THRUSTER, without active action by the operator. This will give the operator time to locate and Select OFF on the thruster system Isolation/Main Switch.

S-link is a Sleipner CAN BUS based control system with full intelligent communication between all devices within the system, much like a computer network. It is used for all retract thrusters and Pro thrusters with a DC control system.
Main advantages include:
• Round, compact and waterproof plugs with unique keying and color coding to avoid faulty hookups.
• An unlimited number of commands or information transfer on a single cable.
• It has user feedback to panel
• Intelligent troubleshooting

Sleipner recommends that the thrusters are connected to a battery bank that is not protected by a Battery Management System (BMS). Typically this means lead-acid, AGM, gel, or similar kinds of batteries. This is important because thrusters draw a lot of currents quickly, and the high amp draw may lead the BMS system to think that there is an issue with the system and consequently disconnect the batteries from the circuit, in which case you would lose maneuverability.
If you have Lithium batteries powering your thrusters, the best advice we can give you is to check the actual voltage measured on the thrusters during operation. Sleipner thrusters are designed to operate within a specific voltage range, and as long as you are within these boundaries, it doesn’t matter for the thruster if the current is delivered by this or that battery pack.
It may also be a very good idea to check the actual current drawn from the battery during full power at the thruster to see that you are not at the limit for the BMS to avoid sudden loss of maneuverability if the BMS disconnects the battery.
With installations where the battery pack is far from the thruster, the higher voltage delivered by LiFePO4 or similar batteries might not be a problem as you will experience a voltage drop through the long cables.
Always make sure you measure your voltage on the thruster to avoid the risk of early thruster wear.
As battery tehcnology is changing rapidly, we always recommend consulting a professional battery supplier.
