TO
START
ENGINE
Before
starting the
new
engine
check
the
oil level in the
crankcase
check fuel in
tank
and
ventilate
engine
compartment
thoroughly Shift
the
reverse
gear
to
neutral
posi
tion
Open
the throttle
slightly
approximately
1 8
open
Turn
switch
on
operating
fuel pump
until fuel
lines
fuel filter and carburetor
are
full
Then
depress
starter
button
or
turn key
all
the
way
to
the right
to
engage
the
starter
Do
not
engage
the
starter
for
prolonged periods
If the
engine
does
not start
immediately
investigate
the
cause
of trouble As
soonas
the
engine
starts release the starter Check
to make
sure
that oil pressure
is
present
and that
cooling
water is
circulating
This
engine
is
equipped
with
an
automatic
choke
If
the
engine
does
not
start
due
to
flooding the throttle
should be
opened fully which will
reduce the
choking action
The
starter
should
be
engaged with
throttle
opened fully
As
soon as engine
starts
close
the throttle
When
taking
the
boat out
always
run
the
engine at
moderate
speed until the oil
warms
up
When
returning always
allow the
engine to
run
slowly for
several minutes before
shutting it
off
This will
greatly extend the life of
the
valves
To
accomplish this
many
owners plan
to idle
their
engines
for the last several hundred
yards
travelled
Before engaging
or
disengaging
the
reverse gear
it is advisable
to slow the
engine down
to
1000 RPM
or
less Shifting
at higher
RPM will shorten the life of the
reverse
gear
and may
cause
damage
LUBRICATION

the habit of
watching
the oil
pressure
gauge

approximately
18
lbs at
idle
speed
and
35
to 45 lbs
at
maxi
mum

with the
engine
hot
ENGINE OIL
RECOMMENDATION
Chris Craft Marine
Engines
should be serviced with oil of
good
character and
quality
to insure
smooth
operation
freedom from trouble and best
engine performance obtain
able A Marine
engine
works at
maximum capacity 90
of the time while
an
automo
bile
engine rarely
works
at
it s maximum
even
10 15
percent
of the time
Therefore
the
requirements
for
a
good
lubricating oil are far
greater
in
a
marine
engine
We recommend
the
use
of
S
A E
430
lubricating
oil
containing detergents and addi
tives
conforming
to
API
designation
MS
or
DG U
S
Military
Spec
MIL L 2 104A
or supplement 1
or
IC E I
designation A
or
B It is not
recommended that
different brands of oil
be mixed
Always replenish
with the
same
make and
type
of
oil that is in the crankcase If it is
necessary
to
change
the make of
oil
always
drain
the crankcase
as
completely
as
possible before
refilling
TO CHANGE ENGINE OIL
The
new engine
when
shipped
is
filled with S A E
10
break in oil
After
ten to
fif
teen hours
running
this
oil should be
replaced
with
S
A
E 30
motor oil
Thereafter
the oil
should
be
changed
every
fifty to
one
hundred hours
depending
upon
the
type
of
