service to
which the
engine
is
subjected
An
engine
that is used for short
runs
needs
an
oil
change
more
often
than
an
engine
which
is
run
longer
periods
of
time
as
long
runs
permit
the
oil to attain
proper
operating temperature
at
which there is less
possibility
of contamination and the oil will
remain
clean
longer
To
remove
the old oil from the
crankcase
the best method is
to pump
the oil
out
with
a
suction
pump
The
suction
tube
maybe
inserted
into
the oil
test rod
opening
or
through
the

plugged
hoe
on
the
side
of the oil
pan next to the test
rod
hole
The
oil
may
be
pumped
out
of the
reverse
gear
except Paragon
Hydraulic
gears
by
removing
the
reverse

top
cover
and
pumping
the oil
out
of this unit
On
engines
withreduction

there will remain
from
1

quarts
in that unit
which
cannot
be
removed
Most marine
service
stations
are
equipped
with
special
pumps
for this purpose
A
suitable hand pump may be
purchased
from the Chris
Craft Service Parts
Department
at
Algonac Michigan
Direct drive Model 283
engines
hold
approximately
7
quarts
of oil but
this
amount
will vary
depending
upon the

Engines
equipped
with
reduction gears
will
hold

It is
important
that all
electrical connections be
periodically inspected
to
make
cer
tain that the
condition of
the
insulation
on
wires
is
good
all
mechanical
connections
are
tight
and all
connections
are
free from
corrosion
In boats
operated
in
salt
water
it is
especially important
that all
connections
be
inspected
two
or
three
times
each
year
If necessary
each
connection
should be taken
apart
cleaned
with fine
sand
paper
given
a
light coating
of vaseline
to
retard
corrosion
and
tightly
reconnected
Battery
terminals should be cleaned often with
water and
baking
