ANTI-CORROSION
PROTECTION
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.
