Long-Term Storage; Prepare Engine For Long-Term Storage - Yanmar 3JH5E Operation Manual

LONG-TERM STORAGE

If the engine will not be used for an
extended period of time, special measures
should be taken to protect the cooling
system, fuel system and combustion
chamber from corrosion and the exterior
from rusting.
The engine can normally stand idle for up
to 6 months. If it remains unused for longer
than this, please contact your authorized
Yanmar Marine dealer or distributor.
Before performing any storage procedures
within this section, review the Safety
section on page 5.
In cold temperatures or before long-term
storage, be sure to drain the seawater from
the cooling system.
NOTICE
DO NOT drain the coolant system. A full
coolant system will prevent corrosion and
frost damage.
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).
