Draining of open cooling circuit 
Seawater circuit 

 
To  avoid  any  deposits  or  accumulation  of  salt  in  the 
seawater  part  of  the  cooling  circuit,  you  must  rinse  it 
with fresh water. 
-Close the seawater intake valve. 
-Drain the seawater intake pipes, the filter 

35

 (optional, 

and may be specific to boat), the seawater pump 

34

, and 

the temperature exchanger pipe by loosing the mounting 
clamps. 
-Drain the exhaust circuit as a certain quantity of water 
will remain in the exhaust «  waterlock ». 
 
 

Draining of engine and gearbox oil and filling with 
new oil 
Draining of engine casing oil (see page A-5).  

-The oil is removed using  a drain pump 

25

, preferably: 

engine slightly warm. 
-Fully pump out all the oil. 
-Fill with new oil. 
-Check the oil level using the gauge. 
-Do not exceed the maximum level. 
 

 

Hot  oil  can  burn.  Avoid  any  contact  with  the 

skin. 
Observe the environment protection rules. 

 

To drain the oil in the gearbox, refer to its specific 
manual.

Wintering 

 

Before  removing  the  boat  from  the  water  for  winter  or 
off-season, contact a NANNI INDUSTRIES – approved 
shop to check the engine and other equipment. 
The  wintering  procedure  is  aimed  at  safeguarding  the 
engine and transmission during the annual period during 
which  it  is  not  used.  These  operations  will  ensure  that 
your engine is in perfect operating condition for the next 
season. 

We recommend that you have these wintering 

operations 

performed 

by 

a 

NANNIDIESEL-

approved  shop.  For  more  information,  refer  to  the 
service and maintenance section. 

 
List of wintering operations:

 

 

Check of condition of coolant. 

 

Rinsing of seawater cooling circuit with fresh water. 

 

Suction  of  mixture  formed  by  50%  water  and  50% 

antifreeze in seawater circuit previously cleaned (for 
storage  during  winter  where  outdoor  temperatures 
may  be  negative,  we  recommend  that  you  drain  the 
seawater  circuit):  see  seawater  circuit  rinsing 
procedure. 

 

Blanking of engine air intake. 

 

Draining  of  oil  in  engine  and  gearbox,  and  filling 

with new oil. 

 

Release of belt tension. 

 

Removal  of  seawater  pump  turbine  (store  dry  after 

rinsing with fresh water, in a location sheltered from 
light). 

 

Filling  of  temperature  exchanger  with  coolant  to 

maximum level. 

 

Drying of bilges under engine. 

 

Spraying  of  waterproof  protecting  product  on 

engine. 

•

 

Extended storage 

For extended storage before or after initial use of the 
engine, a set of special measures must be carried out. 
Contact your NANNI approved technician. 
 
 
 
 
 

8.TROUBLESHOOTING 

 
This section will help you to understand various 
problems which may occur on marine engines. 
However, the surest way to correct a problem is to 
contact a qualified technician. 

TQAN

 stipulates that the 

operation must be performed by a NANNI 
INDUSTRIES-approved qualified technician. The 
"corrective actions" indicated follow the procedures 
defined in section 7. "Servicing and maintenance", 
under the detailed operations heading.
