Flushing The Water Passages - Suzuki DF4 Manuel Du Propriétaire

FLUSHING THE WATER
PASSAGES
ENGINE RUNNING – Vertical position –
Suzuki recommends that you flush the water
passages by using this method.
 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.

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.
1. Shift the motor into "NEUTRAL".
2. Remove the propeller from the motor. Refer
to the PROPELLER SELECTION AND
INSTALLATION section.
3. Install the motor on a large container such
as an empty 55 gallon drum.
4. Fill the container with clean, fresh water as
illustrated.
5. Start the motor and let it idle for about five
minutes. This will clean the salt water out of
the cooling system.
6. Shut off the motor. Remove the motor from
the container and maintain motor in a verti-
cal position until the engine has drained
completely. Reinstall the propeller as out-
lined in the PROPELLER SELECTION AND
INSTALLATION section.
7. Clean the motor surface and apply a coat of
automotive wax on the external finish of the
motor.
