Always visually check the water around the bow before activating the thruster. The suction can pull objects or swimmers into the tunnel.
Check the sacrificial anode thickness; replace it if more than 50% is consumed. Do you need help finding specific wiring schematics
QL bow thrusters use a high-torque electric motor connected to a submerged propeller via a gear leg. The system modifies the vessel's pivot point, allowing sideways movement of the bow during docking or slow-speed tight maneuvers. Key Components
QL bow thrusters were manufactured in various sizes, typically measured by thrust output (e.g., QL BP300, BP450, BP600, BP800, BP1200).
