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
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 replacement of inter-
nal anodes attached to the power unit.

Checking battery (for electric start
models)
EWM01902
Battery electrolyte is poisonous and caus-
tic, and batteries generate explosive hy-
drogen gas. When working near the
battery:
● Wear protective eye gear and rubber
gloves.
● Do not smoke or bring any other source
of ignition near the battery.
The procedure for checking the battery varies
for different batteries. This procedure con-
tains typical checks that apply to many batter-
ies, but you should always refer to the battery
manufacturer’s instructions.

A poorly maintained battery will quickly
deteriorate.
