3.4 Long Term Storage
(1) In cold temperatures or before long
term storage, be sure to drain the
seawater from the seawater cooling
system.
Drain seawater from the seawater
cooling system after the engine has
cooled down. Be careful to avoid
burns.
If seawater is left inside, it may
freeze and damage parts of the
cooling system (fresh water cooler,
seawater pump, etc.) when ambient
temperature is below 0°C[32°F].
1. Loosen the drain cocks/plugs at-
tached on the pipe and on the heat ex-
changer, and drain off the seawater
inside.
If no liquid comes from the drain
cocks/plugs, it may be necessary to
use a stiff wire to remove any debris to
allow drainage.
2. Loosen the 4 bolts attaching the side
cover of the seawater pump, remove
the cover and drain the water from in-
side.
Retighten the bolts when finished.
3. Close the drain cocks/plugs.
(2) Do not drain fresh water/coolant in
the cold season or before the long
storage.
If LLC (Long Life Coolant) has not
been added to the cooling fresh water,
be sure to add LLC or drain off the
fresh water from the fresh water cool-
ing system daily after use
If the fresh water without LLC is not
removed, it may freeze and damage
parts of the cooling water system
(fresh water cooler, cylinder block,
cylinder head, etc.) when ambient
temperature is below 0°C[32°F].
1. Open the fresh water drain cocks/
plugs (2 positions as illustrated) and
drain the fresh water from inside.
2. Close the drain cocks/plugs after
draining the fresh water.
