View ProductWhat This Anode Kit is Used For
The Tecno Seal VER4 anode kit is used to help protect compatible Mercury Verado and OptiMax outboards from galvanic corrosion.
Sacrificial anodes help reduce corrosion damage to lower units, brackets, cooling passages, and other submerged metal components exposed to freshwater or saltwater environments.
Regular inspection and replacement of worn anodes is an important part of routine outboard maintenance, especially for boats stored in the water or operated in saltwater conditions.
Aluminum anodes are commonly preferred for many modern marine applications because they provide strong corrosion protection in both freshwater and saltwater use.
