Sacrificial Anodes
Galvanic corrosion occurs in fresh or salt water.
Salt, brackish, and polluted water can accelerate
corrosion. “Sacrificial” anodes are intended to pro-
tect the underwater metal components of the out-
board from galvanic corrosion.
Outboards are equipped with sacrificial anodes.
Visually inspect anodes and metal components
below water level. Erosion of anodes is normal
and indicates the anodes are functioning properly.
IMPORTANT: Anodes that are not eroding may
indicate that the anodes are not properly
grounded. Anodes and the mounting screws must
be clean and tight for effective corrosion protec-
tion.
