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 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.
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, page
11
for
the BCD 4.4KW, and page
15
for
the BCD 6.0KW.)
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.
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.
