56 INSPECTION AND MAINTENANCE
Washing outboard motor
If outboard motor is used in salt
water, brackish water or water with a
high acidic level, use fresh water to
remove salt, chemicals or mud from
exterior and cooling water passage
after every cruising or before storing
outboard motor for long time. Before
flushing, remove the propeller and the
forward thrust holder.
!
Keep cooling water passage free of
clogs, or lack of cooling water flow
could lead to engine overheating, po-
tentially resulting in engine trouble.
Notes
It is recommended to check chemical
properties of water on which your
outboard motor is regularly used.
!
10
Do not start engine without removing
propeller, or accidentally turning
propeller could cause personal injury.
!
Never start or operate the engine
indoors or in any space which is not
well ventilated. Exhaust gas contains
carbon monoxide, a colorless and
odorless gas which can be fatal if
inhaled for any length of time.
