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.

Do not paint anodes, as this would render
them ineffective.

Inspect ground leads attached to external an-
odes on equipped models. Consult a
Yamaha dealer for inspection and replace-
ment of internal anodes attached to the pow-
er unit.
