Submerged housing containing the oil-lubricated or sealed gears that transfer power to the propeller.
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 Test voltage at the thruster motor input terminals

Located inside the hull; provides high-power, short-duration thrust.
The QL series features compact, high-torque electric DC motors connected to a submerged propeller via a streamlined gear leg. These units operate on either 12V or 24V DC systems, depending on the specific model (such as the popular QL BP300, BP600, or BP800 series). Core Components
For boaters operating in freezing climates, preparing the thruster for storage prevents water-expansion damage.
