To avoid battery explosion and serious
damage to the electrical system:

●

Do not reverse the polarity of the jumper
cables when connecting to the batteries.

●

Do not connect the negative (–) jumper
cable to the negative (–) terminal of the
watercraft battery.

●

Do not touch the positive (+) jumper ca-
ble to the negative (–) jumper cable.

(1) Connect the positive (+) jumper cable to

the positive (+) battery terminals of both
batteries.

(2) Connect one end of the negative (–)

jumper cable to the negative (–) battery
terminal of the booster battery.

(3) Connect the other end of the negative (–)

jumper cable to an unpainted bolt on the
cylinder head.

(4) Start the engine, and then disconnect the

jumper cables by reversing the steps
above.

NOTICE:

Never push the start

switch while the engine is running. Do
not operate the start switch for more
