FLUSHING THE WATER
PASSAGES
After operation in muddy, brackish, or salt
water, you should flush the water passages and
motor surface with clean, fresh water.
If you do not flush the water passages, salt can
corrode the motor and shorten its life. Flush the
water passages as follows.
ENGINE RUNNING – Vertical position –
Suzuki recommends that you flush the water
passages by using this method.
To flush the water passages, you must obtain a
commercially available engine flush device.
WARNING
Exhaust gas contains carbon monoxide, a
dangerous gas that is difficult to detect
because it is colorless and odorless. Breath-
ing carbon monoxide can cause death or
severe injury.
Never start the engine or let it run indoors or
where there is little or no ventilation.
WARNING
Failure to take proper precautions when flush-
ing the water passages can be hazardous.
When flushing the water passages, always
take the following precautions:
• Make sure that the engine remains in NEU-
TRAL. If shifted into gear, the propeller
shaft will turn and could cause severe per-
sonal injury.
• Make sure the motor is properly clamped to
a secure stand or boat, and remain in atten-
dance until flushing is completed.
• Keep children and pets away from the area,
and stay clear of all moving parts.
