Maintaining Ground Circuit Continuity
The transom assembly and sterndrive are equipped with a ground wire circuit to ensure
good electrical continuity between the engine, transom assembly, and sterndrive
components. Good continuity is essential for the MerCathode System to function
effectively.
Anodes and MerCathode System Locations
IMPORTANT: Replace sacrificial anodes if eroded 50 percent or more.
The following sacrificial anodes are installed at different locations on your power package.
These anodes help protect against galvanic corrosion by sacrificing its metal to be slowly
eroded instead of the metal components on the power package.
MerCathode System— Electrode assembly replaces the Anode block. System should be
tested to ensure adequate output. The test should be performed where boat is moored,
using Quicksilver Reference Electrode and Test Meter.
