MerCathode
System
The MerCathode reference electrode and
anode are mounted to the composite cover on
the underside of the drive. The MerCathode
controller is mounted on the transmission. The
controller harness connects the components.
Other sacrificial anodes, if equipped, may be mounted on the vessel to protect against galvanic corrosion. Refer to the operation
and maintenance manual provided by the boat manufacturer for additional information about vessel mounted anodes.

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.
