Inspecting and replacing anode(s)

Yamaha outboard motors are protected from
corrosion by sacrificial anodes. Inspect the
external anodes periodically. Remove scales
from the surfaces of the anodes. Consult a
Yamaha dealer for replacement of external
anodes.
ECM00720
CAUTION:
Do not paint anodes, as this would render
them ineffective.
NOTE:
Inspect ground leads attached to external
anodes on equipped models. Consult a
Yamaha dealer for inspection and replace-
ment of internal anodes attached to the pow-
er unit.
