If you are retrofitting or reinstalling a unit, the QL manual emphasizes several critical "Golden Rules":
Use high-grade, heavy-gauge tinned marine copper wire. Consult the manual’s distance-to-gauge matrix (typically 50mm² to 95mm² depending on the run length).
Use the drawing tool provided in the manual to mark the tunnel hole. It is crucial to ensure the tunnel is exactly 90° abeam. Ql Bow Thruster Manual

The QL bow thruster provides lateral thrust for improved low-speed maneuvering and docking. Typical models are tunnel or pod installations with electric or hydraulic drives; QL focuses on compact units for small-to-mid sized recreational boats.
Never operate the thruster while the boat is out of the water. The propeller and shaft bearings rely on surrounding water for cooling and lubrication. It is crucial to ensure the tunnel is exactly 90° abeam
The QL range was designed for vessels from 22 to 75 feet. Common models listed in the QL Thruster Programme include:
