Type of Water:

  • Saltwater - Zinc
  • Brackish - Aluminium
  • Freshwater - Magnesium

The specifications are, in certain cases, more stringent than any other marine materials standards in the world. If 50% or more of the anode has been eaten away by corrosion it must be replaced in order to, once more, fulfil its vital function.

Never Jeopardize saftey and performance by fitting a non-genuine anode. Remember to never paint over the anodes.

Zinc and aluminum anodes will if left in freshwater become covered with white oxide which effectively passivate the anode, zinc anodes suffer a similar problem even in brackish water.

If the anode becomes passive, the drive will start to sacrifice itself, this will cause serious damage. Magnesium anodes will wear off much to fast in saltwater.
