This 3.00 kg Tecnoseal aluminum anode protects hulls, rudders, trim tabs, and other underwater metal parts against galvanic corrosion. The anode gradually decomposes instead of the metal parts it is mounted to protect.
The aluminum anode is suitable for use in both saltwater and brackish water. Aluminum has a higher negative potential than zinc and, according to product data, provides longer active protection over the anode's lifespan.
When installing, the contact surface must be cleaned of paint and rust to ensure direct metal-to-metal contact between the anode and the part to be protected. The anode must not have physical contact with zinc anodes, as the aluminum anode would otherwise protect the zinc anode.
