LAY-UP AND RECOMMISSIONING 
General 
Many owners rely on their boatyards to  prepare their craft, including engines and generators,  for  lay-up 
during the off-season  or for  long  periods 
of 
inactivity.  Others  prefer 
to 
accomplish lay-up  preparation 
themselves. 
The procedures which follow  will allow you  to perform your own  lay-up and recommissioning, or to use 
as a check list 
if 
others do the procedures. 
These procedures should afford your engine protection during a lay-up and also help familiarize you with 
the maintenance needs 
of 
your engine. 
If 
you have any questions regarding lay-up procedures, call your local  servicing dealer;  he  will 
be 
more 
than willing to provide assistance. 
Fresb 
Water 
Cooling System 
A 50-50 solution 
of 
antifreeze and fresh water 
is 
recommended for use in the fresh water cooling system at 
all times.  This solution may require a higher concentration 
of 
antifreeze, depending on the area's winter 
climate.  Check the solution to make sure the antifreeze protection is adequate. 
Should more antifreeze be needed,  drain an appropriate amount from  the engine block and add a more 
concentrated mixture.  Operate the engine to ensure a complete circulation and mixture 
of 
the antifreeze 
concentration throughout the cooling system. 
Now 
recheck the antifreeze solution's strength. 
Lubrication System 
With the engine warm,  drain all the lubricating oil from the oil sump.  Remove and replace the oil filter. 
(place some paper towels and a plastic bag around the filter 
to 
catch the oil during its removaL) 
When installing the 
new 
oil filter,  be sure 
to 
apply a  small  amount 
of 
oil on the rubber sealing gasket at 
the base 
of 
the  filter.  Fill the  sump with  the correct amount 
of 
oil  for  your engine.  (Refer to  the 
"SYSTEM SPECIFICATIONS"  section 
of 
this manuaL) 
Use 
an oil  with 
an 
API  specification 
of 
CC or 
CD. 
Run the generator and check for proper oil pressure and make sure there are no leaks. 
II 
CAUTION 
II 
Do not leave the engine's old lubricating oil in the sump over the lay-up period.  Lubricating oil 
and combustion deposits  combine 
to 
produce  harmful  chemicals which can  reduce the life 
of 
your engine's internal parts.
