Cleaning and Inspection

Inspection and replacement interval will vary according to the condition of the seawater and the mode of engine operation.

NOTE: Use sandpaper, fiber brush, or cleaning pad, remove the deposits from the surface of the anode before trying to

determine the amount of erosion. Do not use a mild steel brush which might leave deposits that could accelerate corrosion.

1. Remove the deposits.
2. Inspect and measure the anode. Compare the measurements to the specifications for a new sacrificial anode and replace

the anode assembly when deteriorated 50%.

NOTE: Sacrificial anodes are available only as an assembly. Replace both the plug and anode as a unit.
