LAY-UP
&
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 will seive
as
a checklist
if
others
do
the procedures.
These
procedures
should provide protection
for
your
engine/generator during a lay-up and
also
help
familiarize
you
with
its
maintenance
needs.
If
you
have
any
qu~stions
regarding
lay-up
procedures, call
your
local
servicing
dealer.
He
will be more
than
willing
to
provide assistance.
Propeller
Shaft
Coupling
(Propulsion
Engine]
The
transmission
and propeller half
couplings
should
always
be opened
up
and
the bolts removed when
the
boat is hauled
out of the
water
or
moved
from land to
water,
and
during
storage in the cradle.
The
flexibility
of
the boat
oftens
puts a
· severe
strain
on
the propeller shaft or coupling or both,
while
the boat is
taken
out
or
put
in
the
water.
In
some
cases, the
shaft
has
actually
been bent
by
these strains. This
does
not
apply to
small
boats that
are
hauled out of the water
when
not
in
use,
unless
they have been
dry
for
a considerable
period
of
time.
Fresh
Water
Cooling
Circuit
A
SO~SO
solution
of
antifreeze and distilled
water
is
recom-
mended
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
mix-
ture of the antifreeze concentration throughout the
cooling
system.
Then
recheck the antifreeze solution's strength.
Lubrication
System
With the engine
warm,
drain
all
the
engine.oil from
the
oil
sump.
Remove
and replace the oil filter
,and
fill the sump
with
new
oil.
Use
the
correct
grade
of
oil.
Refer
to
the
ENGINE
LUBRICATING
OIL
pages
in
this
manual
for
"engine
oil
change".
Run
the
engine and check for proper oil
pressure
and
make
sure
there
are
no
leaks.

Fuel
System
[Gasoline]
Top
off
your
fuel
tanks
with
unleaded
&asoline
~f ~9
~ctane
or
higher.
A
fuel
conditioner such
as
MARINE:STABIL
stabilizer
should
be
added.
Change
the element in your
gasoline/water
separator and
clean
the
metal
bowl.
Re-install
and
make
certain
there
are
no
leaks.
Clean
up
any
spilled
fuel.
Fuel
System
(Dleselj
Top off
your
fuel
tanks
with
No.2
diesel
fuel.
Fuel additives
such
as
BIOBOR
and
STABIL
should
be
added
at
this
time
to
control
algae
and
condition the
fuel.
Care
should be taken
that.the
additives
used
are
compatible with
the
primary
fuel
filter/water seperator
used
in
the
system.
Change the element
in
ypur
primary
fuel
filter/water
seperator,
if
the
fuel
system
bas
one,
and
clean
the seperator sediment
bowl.
Change the
fuel
filter elements
on
the engine
and
bleed
the
fuel
system,
as
needed.
Start
the
engine
and
allow it to
run
for
5 -
10
minutes
to
make sure
no
air
is
left
in
the
fuel
system.
Check
for
any
leaks
that
may
have
been created
in
the
fuel
system
during
this
servicing,
correcting
them
as
needed.
Operating
the engine
for
5 -
10
minutes
will
help
allow
movement
of
the treated
fuel
through
the
injection
equipment
on
the
engine.
Raw
Water
Cooling
Circuit
Close the
through-hull
fitting.
Remove
the
raw
water
intake
hose from
the
fitting.
Place
the
end of
this
hose
into
a
five
gallon
bucket
of clean
fresh
water.
Before starting
the
engine,
check
the
zinc
anode
found
in
the
primary
heat exchanger
on
the engine
and
clean or replace it
as
required
and
also
clean
any
zinc
debis
from
inside
the heat exchanger
where
the
zinc
anode
is
located.
Clean
the
raw
water
strainer.
Start
the
engine
and
allow
the
raw
water
pump
to draw the
fresh
water
through the
system.
When the
bucket
is
empty,
stop
the
engine
and refill
the
bucket with
an
antifreeze
solution
slightly
stronger
than
needed
for
winter
freeze
protection in
your
area.
Start
the
engine
and
allow
all of this
mixture
to
be
drawn
through
the
raw
water
system.
Once
the
bucket
is
empty,
stop
the
engine.
This
antifreeze
mixture
should protect the
raw
water
circuit
from
freezing
during
the winter
lay-up,
as
well
as
providing corrosion
protection.
Remove
the
impeller
from
your
raw
water
pump
(some
antifreeze
mixture
will
accompany
it, so
cat.ch
it
in
a
bucket).
Examine
the
impeller.
Get a replacement,
if
needed,
and a
cover gasket
Do
not
replace the impeller
(into
the
pump)
until
recommissioning,
but
replace
the cover
and
gasket
Intake
Manifold
and
Thru·Hull
Exhaust
Place a
clean
cloth, lightly
soaked
in
lubricating
oil,
in the
opening of
the
intake manifold
to
block
the
opening.
Do
not
shove the
cloth
out of sight.
(If
it
is
not
visable
at
recommissioning,
and
an
attempt is
made
to
start
the
engine,
you
may
need
assistance
of
the
seivicing
dealer).
Make
a
note
to
remove
the cloth prior to start-up.
The
thru-hull
exhaust port
can
be
blocked
in
the same
manner.
