Battery Installation ‑ Electric Start Models
MOUNTING BATTERY
Follow the battery manufacturer's instructions carefully. Mount
battery in the boat so it is secured against movement, preferably
in a battery box. Make sure battery is equipped with a
nonconductive shield to prevent accidental shorting of battery
terminals.
NOTE: Electric starting outboards must have the battery cables
connected to a battery whenever the engine is running, even if
started manually, as damage to the charging system could
result.
