Anchoring
When the boat is at anchor or in
port for extended period, vegetation
may develop on the hull, the keel,
the drive, the rudder, the propel-
ler, etc. It will significantly affect
the behaviour of the boat and the
performance of the engine if the
vegetation is not removed before
the next time the boat is used.
Vegetation and fouling can also
obstruct the raw water system and
result in damage to the engine by
overheating.
Inspect and clean the boat and the
raw water system each time the
engine is used. Clean if necessary.
If the boat is put out of water, clean
the hull and spray a coat of anti-
fouling. Never paint the anodes.
Furthermore, when the boat is
at anchor or in port for extended
period, water can fill the exhaust
system via the exhaust outlet. It is
necessary to drain regularly the wa-
terlock when the boat is at anchor.
Storage
If the boat is being left in the water
while not in use for few weeks, the
engine must be controlled and run
few minutes every 10 days.
If the boat will not be used for
more than 2 months, special set of
operations must be performed on
the engine and the transmission.
Refer to the chapter
LONG-TERM
STORAGE .
To prevent damages due to freez-
ing, the raw water circuit must be
drained when there’s a risk a frost.
Refer to the corresponding chap-
ters in the section
MAINTENANCE
and to the chapter LONG-TERM
STORAGE .
ALL THESE OPERATIONS
SHOULD BE CARRIED OUT BY
A NANNI AUTHORIZED WORK-
SHOP.
