great
aeal
of
skillful
engineering
careful
manufacture
and
exhaustive

PARTS
All Chris Craft Marine
Engines
have
special
parts designed
to
give
the best
perfor
mance
under conditions found
only
in
marine
use
To
insure
long
life and
dependable
performance
we
strongly
recommend that
only factory replacement
parts
be uaed
These
may
be obtained from your

BR
EAK IN
it is
very
important
that the
engine
be broken in
properly
All
moving parts
in th
engine
are
new
and
have
only
been run
for
a few
hours
while
the
engine
had
its
final
test
Engines
must be
run
carefully
in
the
beginning
until
all
parts
are
worn in and
the
engine
becomes
limber
Only
then will it be
safe to run the
engine
fast for sus
tained
periods
of time
Running
new
engines
or
engines
after a
major
overhaul
at
excessively
low
RPM
for
long periods
should be
avoided
because it
will
tend to
prolong
the
break in
period
and
delay proper seating
of
piston
rings
During
the first hour of
operation
do not exceed 2500 RPM
During
the
next five
hours
operation
do not exceed
3200 RPM
During
the first six
hours of
oPeration running
the
engine
in
excess of these
speeds
for
a
minute at
a time
to
check
engine
perfor
mance
is
recommended
and wi21 aid in
seating
the
piston rings
An abnormal
rise
in
engine
temperature
will indicate that the
engine
is
being
run a little
too
fast
We do
not recommend a
continuous
speedin
excess
of 3600
RPM
Use in
excess of
4000 RPM
voids the
factory warranty
During
the entire life
of the
engine
always
run
the
engine
at
medium
speeds
to
allow
the
oil to
warm
up
before
running
at
sustained
high
speeds
When
coming
tothe dock
after a run
always
allow the
engine
to
run
at
moderate
speed
for three
to five
minutes
before
turning
off
the
ignition
This
can be done
by slowing
down several hundred
yards
before
you
get
to the
dock and
coming
in
slow or
letting
the
engine
idle
after
you
have
come
into the dock This is
to allow
the valves
to
cool down while the
water is
still
cir
culating
in
the
engine
This will
help
prevent warped
valves
TO START ENGIIVE
Before
starting
the
new
engine
check the oillevel 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
18
open

Page

With
ignition key
turn on
switch and
engage
the starter Do not
engage
the starter
for
prolonged periods
If the
engine
does
not start
immediately
investigate
the
cause
of trouble
As
soon as 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
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

ENGINE OIL REGOMMENDATION
Chris Craft Marine
Engines
should
be
serviced
with oil of
good quality
to
insure
smooth
operation
freedom from trouble
and
best
engine performance
obtainable
A
Marine
Engine
works at maximum
capacity
90 of
the
tizne while
an
automobile
engine
rarely
works at its
maximum even
10 15
percent
of the
time
Therefore
the
requirements
for a
good lubricating
oil are far
greater
in a Marine
Engine
Wz
recommend
the
use
of S A E
430
lubricating
oil
containing detergents
and addi
tives
conforming
to API

is
not
recommended that
different brands of oiI be mixed
Always
replenish
with the same make and
type
of
oit
that is in
the crankcase If
it is
necessary
to
change
the
make of
oil
always
drain
the
crankcase as
completeiy
as
possible
before
refilling
TO CHANGE OIL
The new
eng ine
when
shipped
is
filled with S
A E 10 break in oil After fifteen to
twenty
hours of
running
replace
with S A
E 30
motor oil and also
replace
the
filter
element
Subsequent
oil
changes
should be made
every
fifty
to one hundred
hours
de
pending
on the
type
of
servi ce to which the
engine
is
subjected
An
engine
used for
short
runs
only
will r
equire
an oil
change
more often than an
engine
used for
long
runs
During
the
longer
run
the oil attains the
proper
operating temperature thereby
re
ducing
the
po
s
sibility
of c
ontamination
The best method for
removing
crankcase oil is with
a suction
pump
The easiest
me
thod
is
to insert the suction hose
through
the
dip stick
or
throughthe
14
plugged
hole
on the side of the oil
pan
next to the test rod hole
Most marine
service
stations are
equipped
with
special pumps
for
removing
oil
or a
suitable
puznp may
be
purchased
from

OIL FILTER
The oil
filter
element
should be
replaced
in
the new
engine
when the break in
oil
is
removed after fifteen to
twenty
hours
running
Thereafter replace
the
oil filter
ele
ment
every
100
running
hours
If oil
pressure
fluctuates due
to
a
clogged
oil
filter
reduce
speed
and
cha nge
the oil
filter
element
immediately
This
is
a
full flow filtPr
which can restrict
oil
flow if
ciogged
with
dirt
even
though
an oil
bypass
is
incorporated
in its
design
ELECTRICAL
SYSTEM
The electrical
equipment
on the

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
soda
coated with vas
eline
and reconnected
High

be
in
good
condition Even a
small
crack in the
insulation
might
permit
oil or
moisture to
cause a

FUEL
PUMP
V
The fuel

or
electrical
with
which
your

is
equipped
is
war
ranted
by
the manufacturer who
produced
it
l
Electric
fuei
pumps
will often click
or
buzz when
the
ignition
switch is
turned on
This
is inherent
in
their
operation
COOLING
SYSTEM
The model
283
engine
is
equipped
with a
dual water
pump
The two
sections
of the
pump
direct water
equally
to
each
bank of
cylinders
insuring proper
cooling
water
di stribution
Cooling
water is
pumped
first into
the exhaust
manifolds
where it is
preheated
to
re
duce
rapid
temperature change
and
possible
condensationafter
beingrouted
to
thecyl
inder
block
The
cooling
water
after
traveling
the
full
length
of the
exhaust mani
folds and
back
again
is routed
into
the rear end of the
cylinder
block
The water
flows up
around the
cylinder
bor es
and into the
cylinder
heads After
cooling
the valve
areas
in
the
cylinder
heads the water
passes
out
of
the
front of the heads
and
is
con
ducted
to the after end of the
engine through
separate
overflow
passages
in the mani
folds
It leaves the
engine traveling through
the
exhaust
tube
where it
helps keep
the
exhaust
tube
cool
and
helps
to
muffle
engine
noise

on
housing
is
currently
used
Both
type pumps
are
equipped
with
a
water seal
which
is automatic in
action If leak
occurs around
shaft
this seal should be
replaced
A
rubber
impeller pump
can
often be
repaired
by replacing
the rubber
impellers
Re
pair
can be
made
by
rexnoving
and
dismantling
pump
The
bronze
gear pumP with
grease
cup
requires
little lubrication Turn
the cup
one
revolution each
time
oil is
changed
In an
emergency
a
worn
pump
can
be
primed
by
turning
the
cup all the
way
down
forcing grease
around the
pump gears
A
worn
pumP
can
often be
repaired
with new
parts however
if
the
housing
is
worn a
new
pump
should
be
obtained
Cooling
water
hoses should
always
be
kept tight
If seasonal
inspection
shows them to
be soft
or
deteriorated
they
should
be
replaced
YALVES AND
VALVE
TAPPETS
Good
valve action is
very important
to
the
efficiency
and smoothness of the
engine
The
need for valve
grinding
will irst
be
indicated
by
loss of
engine
speed
increased
fuel
consumption
and
rough
idling
A
check of
the
compression
in each
cylinder
is a
reliable
check of valve
condition
Engines
operated with
proper
care will
require
a
minimum
amount of
valve
vaintenance
In the
new
engine
check
valve clearance after ten to
twenty
hours of
operati on
Valves
should be checked
every
100
hours of
operation
and
anytime
thehead is removedor the
head bolts are
adjusted
Clearance adjustments
should
be made while the
errgine
is hot
Intake valve
clearance should
be
4L0 L and exhausfi
valve
clearance should be 02011
REVERSE

PARAGON HYDRAliLIC
REVERSE GEAR
The actual
operation
of the
hydraulic
reverse
gear
is
nearly
the same
as the manual
reverse
gear
except
that
hydr ulic pressure
does the work
in
shifting gears
The
hydraulic
section
of the
reverse
gear
is
completely
contained
within the reverse
gear
housing
For
the
forward drive
no
adjustment
is needed For the reverse
drive
there
is an ad
justment
on
the outside of the starboard
side of the reverse
gear housing
If the
gear
slips
in
reverse drive
remove
the
long
acorn
nut
covering
the
adjustment
screw
Loosen the locknut
and
with the reverse
gear
in
neutral
position
and
the
engineidling
tighten
the
adjustmen t
screw until
the
propeller
shaft
just begins
to turn Then
loosen
the
adjustment
screw
14 turn
tighten
the locknut
and
replace
the
long
acorn nut
The
Hydraulic
Reverse
Gear has
an
oil
supply separate
from
the
engine
and
must
be
checked
and
replaced individually
Hydraulic
fluid should be
changed
once each sea
son
or
every
100
operating
hours
whichever
is first
The level of the
hydraulic
fluid
sh uld reach the
full
mark
on the Reverse
Gear
dip
stick
When
adding
or
replacing
fluid
always
use
Type
A
Automatic
Transmission Fluid
wNNUa
Y uP
In
areas
where
freezing
is a
problem
preparing
the
engine
becomes
a
major
consil
eration because
of the
potential damage
from
freezing
This does
not infer that
lay ups
in
more
temperate
climates are less
important
and therefore less
exacting
A
thorough
lay up operation
will include the
following
steps
1 Drain the
engine
oilandrefill
the crankcase
Add
Ghris Craft Crankcase
Oil
Supplement catalog
number 56 00 20630
in the
proportion
of
16
ozs
for
every
four to
six
quarts
of oil
2 Before
lifting
the boat
from the
water
add
Chris Craft Fuel
Conditioner
and
Valve Lubricant
partnumber

00 20629
to the
gasoline supply
in
the
proportion
of
6
oz
to each 7
gallons
of
gasoline
W
e
suggest running
the
fuelsupplylow
atthe
end of the
season
therebyreducing
the
required
amount
of Fuel
Conditioner
If
preferred
the
treated fuel
may
be
fed
from
anauxiliary
tank An
outboardmotor
gasoline
tankwould serve
very
well for this
purpose
Run
the
engine
for at least
fifteen minutes to dis
perse
the
Conditioner
throughout
the
engine
The
conditioning
properties
lie
in
the residue
resulting
from the combustion of the
Fuel
Conditioner
therefore
it is
very
important
to
run
the
engine
as
directed
During
this
final
running
close the fuel
valves at the tanks and run the
engines
un
til
they
stall
3
R
emove and clean
the sediment bowls
and
replace
them
4
Drain the
entire
cooling system
and flush with fresh water
This is
es
pecially important
for boats

wood
engine
string
ers
running
fore
and
aft
in the
boat with
proper
cutouts for
mounting
the
engine
sup
ports
are
usually
used
ALIGNMENT
Proper alignment
with the
propeller
shaft is
important
for
engine efficiency
and
smoothness
The two
coupling
faces
one
on
engine
and
one on shaft
must be
paral
lel Use a
feeler
gauge
or
piece
of shim stock not more
than
003
inch
in
thickness
When
coupling
faces are
brought
together
by
hand
not
bolted
the
003
feeler
should
be
tightly gripped
at all
points
around the
edges
of the
couplings Alignment
must be
correct
when
couplings
are viewed from the side as
well as when seen from
the
top
It
is
necessary
to lift
lightly
on
the shaft and
coupling
to
compensate
for the
weight
of those two items but be
very
careful that
only
the
weight
is
lifted and the
shaft
is
not
sprung
To
adjust any
misalignment
the corners
of the
engine may
be
raised or
lowered
by using tapered
cast
iron
wedges
In
addition the rear
engine
mounts are
designed
to
permit
lateral
alignment
EXHAUST
The
cooling
water
overflow is routed into the
exhaust tube
directly
out of the exhaust
manifold
The flow of water
through
the
exhaust tube will cool the exhaust
and
in
ad
dition will
help
to
quiet
the exhaust noise
We recommend that
copper
tubing
exhaust
hose or
iron
pipe
of
proper
diameter be
used for the exhaust
pipe Copper tubing
can be
bent
as
needed to fit
a
particular
