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 free-
zing, the cooling systems (raw
water and coolant) must be drained
when there’s a risk a frost. Refer to
the corresponding chapters in the
section
MAINTENANCE and to the
chapter LONG-TERM STORAGE .
All these operations should be
carried out by a Nanni authorized
workshop.
ONLY IN STERN DRIVE VERSION
Before removing the boat out of
water, raise the drive in the lift
range and lock the transmission
using the optional kit or any equi-
valent system. Put the drive in the
lift range and lock the transmission
using the optional kit or any equiva-
lent system.
