Do not pressure‑wash the MerCathode assembly, if equipped. Doing so will damage the coating on the reference electrode
wire and decrease the corrosion protection.

IMPORTANT: Replace sacrificial anodes if eroded 50% or more.
The following sacrificial anodes are installed at different locations on your power package. These anodes help protect against
galvanic corrosion by sacrificing its metal to be slowly eroded instead of the metal components on the power package.
MerCathode System—The electrode assembly, if equipped, replaces the anode block. The system should be tested to ensure
adequate output. Perform the test when the boat is moored, using a Quicksilver reference electrode and test meter. Contact
your Mercury Diesel authorized repair facility.
