Corrosion And Corrosion Protection
Whenever two or more dissimilar metals (like those found on the stern drive) are submerged in a conductive
solution, such as saltwater, polluted water, or water with a high mineral content, a chemical reaction takes place
causing electrical current to flow between metals. The electrical current flow causes the metal that is most chemi-
cally active, or anodic, to erode. This is known as galvanic corrosion and, if not controlled, it will in time cause
the need for replacement of power package components exposed to water.
IMPORTANT: Replace sacrificial anodes if eroded 50% or more.
1
Universal Anodic Plate - serves as a sacrificial anode.
Remove plug from drive shaft housing to access attaching screw and insert 1/2 inch socket. Unthread attaching
screw and remove universal anodic plate. Do not remove screw. Clean or scrape mounting surfaces to bare
metal for proper contact. Install new anodic plate and tighten screw securely. Install plug.
2
Anodic Plate - serves as a sacrificial anode. Unscrew both attaching screws and remove. Clean or scrape
mounting surfaces to bare metal for proper contact. Install a new anodic plate and tighten securely.
3
MerCathode System - should be tested to ensure adequate output..
Test should be made where boat is moored, using Quicksilver Reference Electrode and Test Meter. Contact your
Authorized MerCruiser Dealer to arrange for this test.
