NOTICE
Washing the MerCathode assembly can damage components and lead to rapid
corrosion. Do not use any cleaning equipment such as brushes or high‑pressure washers
to clean the MerCathode assembly.
Do not pressure‑wash the reference electrode of the MerCathode assembly. Doing so
damages the coating on the reference electrode wire and decrease the corrosion
protection.

MerCathode System Testing
If the boat is equipped with a Quicksilver MerCathode system, test the system to ensure
that it is providing adequate output to protect the underwater metal parts on the boat. The
test should be made where the boat is moored, using a Quicksilver Reference Electrode
and Test Meter.
