Corrosion Protection
Mercury MerCruiser power packages are equipped with anodes to help protect them from
galvanic corrosion under moderate conditions. However, for severe conditions or if using
a stainless steel propeller, it is recommended that a Quicksilver Anti-Corrosion Anode Kit
and/or a MerCathode System be installed (some models have a MerCathode System as
standard equipment). 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 “Quicksilver
Mercury Precision Parts / Quicksilver Accessories Guide” for part numbers.)
Boats which 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 anodes may be unable to handle the increased galvanic corrosion
potential.
Refer to Marine Corrosion Protection Guide P/N 90-881813 01 for specific information about
marine corrosion.
