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.
 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.
NOTICE
Severe engine damage can occur in as little 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.
To flush the water passages, you must obtain a
commercially available engine flush device.
1. Make sure that the motor is stopped.
2. Plug the water intake hole 1 with a piece of
duct tape. (except DF50AV/60AV model)
3. Install the flushing attachment 2 so that the
water intake holes are covered by the rubber
cups on the attachment.
4. 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 rubber cups
on the attachment.
5. Shift the motor into “NEUTRAL” and remove
the propeller. Start the motor and allow it to
run at idle.
6. Readjust the water flow, if necessary, so
that there is still plenty of excess water flow-
ing out from around the rubber cups.
7. Allow the water to continue circulating for a
few minutes.
8. Stop the motor, then turn off the water.
9. Remove the flushing attachment and
remove the duct tape from the water intake
hole.
10. Clean the motor surface and apply a coat of
automotive wax on the external finish of the
motor.
