Proper anodes are good insurance against costly corrosion.
Marine corrosion can cause major damage to your boat, if left unattended.
Several factors that influence the severity of corrosion: water salinity & movement, electrical grounding, and dissimilar metals.
Some types of bottom anti-fouling paint can also contribute to metal corrosion.
Some tips to help prevent corrosion to the running gear of your boat.
Make sure your engines, outdrives, & outboards, are grounded properly.
Make sure the shore power to your vessel is properly wired and grounded.
Make sure the Marine or Dock your vessel resides at, does not have stray current in the surrounding water.
Make sure that any metal parts underwater are protected with cathode protection.
The “zinc’s” or sacrificial anodes should be of the type to provide protection in the type of water the vessel is moored/stored in.
Saltwater, Brackish water, and Fresh water all require different types of anodes to provide the best protection.
Marine Corrosion will usually consume the softer metal when several types are submerged together.
Make sure the only metal sacrificed, is the anode that is designed to do so.
Check the anodes regularly to see that they are eroding, and not your vessels expensive machinery.
