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.

TIP:
Inspect ground leads attached to external an-
odes on equipped models. Consult a Yamaha
dealer for inspection and replacement of inter-
nal anodes attached to the power unit.
