A set of operations must be per-
formed to prepare and protect the
engine for a long-term storage.
Refer to the corresponding chapter
in the MAINTENANCE section to
perform some of these operations.
We recommend that you have all
these operations carried out by a
Nanni authorized workshop.
NOTICE: It might be necessary to
adapt these operations depending
the climatic conditions. Contact
a Nanni authorized workshop for
further informations.
For prolonged storage (>12
months), a specific set of meas-
ures must be performed. All these
operations should be carried out by
a Nanni authorized workshop.
I CAUTION
If the engine is likely to be
subject to frost, drain all water in
the seawater circuit.
