WARNING
Leaking fuel is a fire hazard. When
G
transporting and storing the outboard
motor, close the air vent screw and fuel
cock to prevent fuel from leaking.
USE CARE when transporting fuel tank,
G
whether in a boat or car.
DO NOT fill fuel container to maximum
G
capacity. Gasoline will expand consid-
erably as it warms up and can build up
pressure in the fuel container. This can
cause fuel leakage and a potential fire
hazard.

WARNING
Never get under the lower unit while it is
tilted, even if a motor support bar is used.
Severe injury could occur if the outboard
motor accidentally falls.
ECM00660
CAUTION:
Do not use the tilt support lever or knob
when trailering the boat. The outboard
motor could shake loose from the tilt sup-
port and fall. If the motor cannot be trail-
ered in the normal running position, use
an additional support device to secure it
in the tilt position.
The outboard motor should be trailered and
stored in the normal running position. If there
41
is insufficient road clearance in this position,
then trailer the outboard motor in the tilt po-
sition using a motor support device such as
a transom saver bar. Consult your Yamaha
dealer for further details.

Storing outboard motor

When storing your Yamaha outboard motor
for prolonged periods of time (2 months or
longer), several important procedures must
be performed to prevent excessive damage.
This is especially important for your oil injec-
tion-equipped outboard motor due to the
lean oil ratios used at idle prior to shutting the
engine off for the season. It is advisable to
have your outboard motor serviced by an au-
thorized Yamaha dealer prior to storage.
However, you, the owner, with a minimum of
tools, can perform the following procedures.
ECM01150
CAUTION:
Do not use any chemical goods con-
G
taining Silicon, Phosphorus, or Lead.
Otherwise the oxygen sensor for the
G
Electronic Fuel Injection system could
be damaged. Consult your Yamaha
dealer for details on the use of chemical
goods for storage.
Drain the remaining gasoline from the
G
vapor separator. Gasoline left in the va-
por separator for a prolonged period of
time will break down and could cause
damage to the fuel line.
