Tecnoseal BTQ185 Quick Zinc Propeller Nut Anode Kit

The Tecnoseal Quick Zinc Propeller Nut Anode Kit BTQ185 fits bow thrusters with a 185 mm diameter tunnel. It replaces the propeller nut with an anode. That protects the thruster's propeller and lower housing.

Zinc is the traditional choice for saltwater use, but it isn't suited to fresh water, where it can develop a coating that stops it from working. Most thrusters need two anodes, one for each propeller. The mounting screw is not included.

Thruster anodes are easy to forget because the tunnel is out of sight. Check them at every haul-out. Other thruster anodes are in our marine anodes section.
