Flushing The Water Passages - Suzuki DF350A Owner's Manual

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
passage 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.
Breathing 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
flushing the water passages can be haz-
ardous.
When flushing the water passages,
always take the following precautions:
• Make sure that the engine remains in
NEUTRAL. If shifted into gear, the pro-
peller shaft will turn and could cause
severe personal injury.
• Make sure the motor is properly
clamped to a secure stand or boat, and
remain in attendance until flushing is
completed.
• Keep children and pets away from the
area, and stay clear of all moving parts.
NOTICE
Severe engine damage can occur in as lit-
tle as 15 seconds if the engine is started
without supplying water to the cooling
system.
Never start the motor without supplying
water to the cooling system.
1. Make sure that the motor is stopped.
2. Install the flushing attachment (Suzuki genu-
ine part) 1 so that the water intake hole is
covered by the attachment.
NOTE:
• Consult your authorized Suzuki marine
dealer for Suzuki genuine parts.
• Refer to the "Flushing Attachment Instruction
Manual" supplied with the product for detailed
operating instructions.
3. Connect a garden hose to the flushing
attachment and turn on the water to obtain
enough flow so that plenty of excess water is
flowing out from around the attachment.
4. Make sure that the cooling water is dis-
charged from the auxiliary water supply
ports 2 and 3.
