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.

Battery Connections

DISCONNECTING OUTBOARD BATTERY CABLES
1. First, disconnect the black battery cable from the (‑) negative terminal and then disconnect the red battery
cable from the (+) positive terminal.
