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.
