CORROSION PROTECTION

This power package is equipped with various anodes and a MerCathode System. A
MerCathode Monitor also is available to allow the operator to check the operation of the
MerCathode System with the push of a button. Refer to Mercury Precision Parts /
Quicksilver Accessories Guide for part numbers.
Boats that are connected to AC shore power require additional protection to prevent
destructive low voltage galvanic currents from passing through the shore power ground
wire. A Quicksilver Galvanic Isolator can be installed to block the passage of these currents
while still providing a path to ground for dangerous fault (shock) currents. Refer to Mercury
Precision Parts / Quicksilver Accessories Guide for part number.
IMPORTANT: If AC shore power is not isolated from boat ground, the MerCathode
System and zinc anodes may be unable to handle the increased galvanic corrosion
potential.
