LONG-TERM STORAGE
BEFORE YOU PLACE THE
ENGINE IN LONG-TERM
STORAGE
Before performing any storage procedures
within this section, review the Safety section
on page 4.
In cold temperatures or before long-term
storage, be sure to drain the seawater from
the cooling system.
WARNING! NEVER remove the coolant
filler cap if the engine is hot. Steam and
hot engine coolant will spray out and
seriously burn you. Allow the engine to
cool down before you attempt to remove
the cap.
CAUTION! DO NOT drain the coolant
system. A full coolant system will
prevent corrosion and frost damage.
CAUTION! If seawater is left inside of the
engine, it may freeze and damage parts
of the cooling system when the ambient
temperature is below 0°C (32°F).
1. Loosen the seawater drain cocks
(Figure 1, (1)), (Figure 2, (1)) and drain
the seawater.

If no liquid comes from the drain cocks,
it may be necessary to use a stiff wire to
remove any debris to allow drainage.
2. Loosen the six bolts attaching the side
cover of the seawater pump, remove the
cover and drain the water from inside.
Retighten the bolts when finished.
