The Mercathode anti corrosion system used on stern drives. Is anyone familiar with the Magnesium anodes that are optional for use in fresh water? Are there any issues that differ from the Zinc anodes? Magnesium anodes available for the Mercury K-planes?
Doesn't seem like many folks know about the fresh water salt water system. Apparently the Zinc works in both types of water but the Magnesium is better in fresh water and is an option. $100 for the set at the Mercury dealer.
