Bowthruster systems have become essential for precise maneuvering in tight spaces, and the Lewmar Bowthruster Black Box (model 559003) plays a vital role in this setup. This component is designed to work seamlessly with Lewmar's Gen 1 TT140 2.2 and higher thruster models, ensuring smooth operation and control.

Understanding the Black Box

The Lewmar 559003 Black Box is essentially a semiconductor switch that drives the contactors on the DC thruster motor. It serves as an intermediary between the control panel and the main contactors, translating user input into the appropriate electrical signals to activate the thruster.

Key Features:

  • Compatible with Gen 1 TT140 2.2 and higher models
  • Allows for negative switching operation
  • Designed for easy replacement and installation

Installation and Wiring

The black box typically connects to a control panel via a 4-wire system:
  • Black (0V)
  • Red (12V)
  • Blue (port)
  • Grey (starboard)

These wires route to the black box, which then activates the main contactors. This setup allows for precise control over the thruster's direction and power.

Frequently Asked Questions

What is the purpose of the Lewmar Bowthruster Black Box
The black box acts as a control interface between the user panel and the thruster motor, translating commands into the appropriate electrical signals to operate the thruster.

Is the Lewmar 559003 compatible with all Lewmar thrusters
No, it's specifically designed for Gen 1 TT140 2.2 and higher thruster models. Always check compatibility before purchasing.
