3. Setup and Installation

Proper installation is crucial for the safe and effective operation of the thruster. It is highly recommended that installation be performed by qualified marine technicians.

3.1 Tunnel Installation

• The thruster is designed to be fitted into a tunnel through the boat's bow or a stern tunnel at the boat's stern.
• Sleipner offers solid and durable fiberglass stern tunnels designed to optimize thruster performance and ease of installation.
• The thruster can be mounted at any angle within the tunnel, providing significant flexibility for various hull designs.
• For boats with shallow drafts or obstructions at the stern, additional cowls (sold separately) may be required to facilitate proper installation.

3.2 Motor and Control Unit Placement

• The electric motor can be rotated 90 degrees on its mounting bracket, allowing for optimal positioning relative to available space and cable routing.
• Ensure the control unit and electrical connections are protected from direct water exposure and are easily accessible for inspection.

4. Operating Instructions

The Sleipner SE30 thruster is designed for intermittent use to assist with docking and maneuvering. Avoid continuous operation to prevent overheating.

4.1 Basic Operation

• Ensure the main power switch for the thruster system is engaged.
• Use the control panel or joystick to activate the thruster in the desired direction (port or starboard).
• Apply thrust in short bursts (typically 2-3 seconds) rather than continuous activation to allow the motor to cool and conserve battery power.
• The IPC (Intelligent Power Control) system monitors power usage and protects the thruster from overload.

4.2 Thruster Versions

The SE30 is available in different versions:

• Standard Version: On/off control.
• PRO Version: Offers variable speed control for precise maneuvering.
• IP PRO Version: Includes ignition protection and variable speed control, suitable for specific engine room environments.

5. Maintenance

Regular maintenance ensures the longevity and reliable performance of your thruster.

• Annual Inspection: Visually inspect the thruster unit, propeller, and tunnel for any signs of damage, corrosion, or marine growth.
• Propeller Cleaning: Keep the propeller free from marine growth, fishing lines, or other debris that could impede its rotation or damage the seals.
• Electrical Connections: Check all electrical connections for tightness and corrosion. Ensure the galvanic isolation system is intact.
• Battery Condition: Ensure your boat's battery system is in good condition and adequately charged to provide sufficient power to the thruster.
• Anode Replacement: Inspect and replace sacrificial anodes as necessary to protect against galvanic corrosion.

6. Troubleshooting

If you encounter issues with your thruster, perform the following basic checks before contacting service personnel.

• Thruster Not Responding:
  • Check if the main power switch for the thruster is ON.
  • Verify battery voltage and charge level.
  • Inspect fuses or circuit breakers in the thruster's power circuit.
• Reduced Thrust:
  • Check the propeller for marine growth, fishing lines, or other obstructions.
  • Ensure the thruster tunnel is clear.
  • Verify battery health and connections.
• Unusual Noises or Vibrations:
  • Immediately cease operation.
  • Inspect the propeller for damage or foreign objects.
  • Contact a qualified technician for further inspection.

For persistent issues or complex problems, it is recommended to consult an authorized Sleipner service center or a qualified marine electrician.
