SERVICE MANUAL NUMBER 28
CORROSION PROTECTION - ALL MODELS
Quicksilver Isolator
Boats that are connected to AC shore power require additional protection to prevent de-
structive low voltage galvanic currents from passing through the shore power ground wire.
A Quicksilver Isolator can be installed to block the passage of these currents, while still pro-
viding a path to ground for dangerous fault (shock) currents.
CAUTION
If A.C. shore power is not isolated from boat ground, the MerCathode System and
sacrificial anodes may be unable to handle the increased galvanic corrosion poten-
tial.

Corrosion Protection Testing and Troubleshooting
NOTE: The following corrosion protection test supersedes all previously issued tests. This
test can be used on applications with or without a MerCathode System.
If the unit is equipped with a MerCathode System, this test should be performed annually
where the boat is moored to ensure that the system is functioning properly.
Test requires the us of MerCathode Reference Electrode Test 76675A1 and Quicksilver
VOA meter 91-62562A1. This meter is no longer available from Mercury Marine. If you do
not already have this meter, a digital multi-meter must be used. A STANDARD ANALOG
METER CANNOT BE USED, AS AN INACCURATE READING WILL RESULT.
IMPORTANT: Quicksilver Volt/Ohm Meter 91–93572 and Multi-Meter DVA/Tester
91-99750
are no longer recommended for testing corrosion protection.
