After running-in is completed, select
the correct propeller so that the
engine speed is the recommended
range at the wide-opon throttle.

After completing 5 hours of break-
in, replace the gear oil with new oil.

Do not operate the outboard motor
in closed area or area with no forced
ventilation.
Exhaust gas emitted by this outboard
motor contains carbon monoxide
that will cause death if inhaled
continuously. Inhaling the gas initially
causes symptoms such as feeling of
sickness, drowsiness and headache.
During operation of the outboard
motor:
• Keep peripheral area well ventilated.
• Always attempt to stay on the
windward side of emission.

Operating the outboard motor without
break-in can shorten service life of the
product.
If any abnormality is experienced
during the break-in:
• Discontinue the operation immediately.
• Have the dealer check the product
and take proper action(s) if necessary.
