Corrosion And Corrosion Protection

Whenever two or more dissimilar metals (like those found on the

sterndrive) 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 chemically 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.

2 Anodic Plate - serves as a sacrificial anode.

3 Block (if equipped) - Is mounted to underside of gimbal housing

and serves as a sacrificial anode.

4 MerCathode System (if equipped) - Electrode assembly

replaces Anodic block.

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

Mercury MerCruiser Dealer to arrange for this test.

5 Anode Kit (if equipped) - Mounted to boat transom. Acts as a

sacrificial anode.
