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 them-
selves.
The procedures which follow will allow you
to
perform your own lay-up and recommissioning, or to use
as
a check list
IT
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
assis-
tance.
Fresh 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
in
the manifold 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 con-
centrated mixture. Operate the engine
to
ensure a complete circulation and mixture of the antifreeze con-
centration throughout the cooling system.
Now
recheck the antifreeze solution's strength in the manifold.
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 model. Use an oil with an
API
specification of SE, SF
or
SG. Run the engine and check for proper oil pressure and make sure there are
no leaks.
CAUTION
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.
Fuel
System
Top off your fuel tanks with regular or unleaded gasoline with an octane rating of 89 or higher. Fuel addi-
tives should be added at this time
to
control algae and condition the fuel. Care should be taken that the ad-
ditives used are compatible with the primary filter/water separator used in the system. Change the element
In your primary fuel filter/water separator, the fuel system should contain one, and clean the separator sedi-
ment bowl. Clean the filter screen at the inlet
to
the carburetor.
