INSPECTION AND MAINTENANCE
Washing outboard motor
When the engine has been used in
salt water or polluted water, wash the
exterior and flush the cooling water
passage with fresh water. The cooling
water passage is flushed by placing
the propeller section of the outboard
in a bucket filled with fresh water,
and operating the engine for about 3
minutes to circulate the water in the
passage.
!
Keep cooling water passage free of
clogs, or lack of cooling water flow
could lead to engine overheating,
9
potentially resulting in engine trouble.
Note
It is recommended to check chemical
properties of water on which your
outboard motor is regularly used.
�������
!
Do not start engine without removing
propeller, or accidentally turning
propeller could cause personal injury.

carbon monoxide, a colorless and
odorless gas which can be fatal if
inhaled for any length of time.

position before washing. (3.5B2 Only)
• When removing the propeller, remove
the plug cap from the spark plug

• Wash the exterior of the outboard
before long-term storage.
• Keep engine at idle speed during
flushing.
