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 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.
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
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 model. Use an oil with an
API
specification
of
SD,
SE
or
SF.
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. Lubricat-
ing 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, if the fuel system contains one, and clean the separator sediment
bowl. Clean the filter screen in the fuel lift pump and in the carburetor.
