ATTACHING TNOTOR
TO BOAT
This motor is designed
for useon a standard15inch
transom. If transom is higher, it shouldbe cut down
to 15 inches so propeller will be at least 2 lnches
below bottom of boat. Best performance will be ob-
tained only by having the driveshaft vertical andthe
propeller placed below bottom of the boat. If the
aboveinstructions are followed, the lowerunitshould
clear the bottom of the boat whenthe motor is turned
to reverse position: however, someboatsmay be so
constructed that the keel will have to be modified
for clearance.
Place motor on stern of boat with stern bracket
clamps inside the stern, centered on the transom
or stern board. Tighten bracket clamp screws se-
curely by hand. Adjust lower unit angle by tilttng
motor slightly. Lift up on lever (Fig. a) andmove
it forward or backward so that lower unit ls in a
vertical position when boat is loaded and running
(see
Fig. 2).
When motor is running, occasionalty check
bracket clamp screws to be sure they are
tlght. We will not be responslble for any
motor damaged or lost overboard due to
loose clamp screws.
The use of a safety chain or rope attachedto motor
stern bracket and boat will guard against Ioss of
motor overboard. Holes are provlded in thumb
screw handles through which a padlock may be ap-
plied to lock the motor on the boat. (SeeFig. 4.)
TUBRICATION
AND FUEL
INSTRUCTIONS
Proper lubricatlon is an important factor in the per-
formance and life of your outboard motor. The
following lnstructions are therefore very important
and shouldbe followed carefullv.
IMPORTANT
The oil and fuel mixture referred to in the following
lnstructlons should always be thoroughly mixed in
a separate container before pouring into motor fuel
taak: NEVER POUR SEPARATELY INTO FUEL
TANK. Also, all fuel should be poured through a
fine mesh strainer to remove dirt and water which
may be present. Use only metal containers.
tMp*,
You are to be congratulated
on your selec-
tion of this outboard motor which ls de-
signed and built to give years of satisfactory
service. The fine materials and hlgh stan-
dards of workmanshlp used assure durability
and lasting performance.
Read these instructions carefully before
attempting to operate your motor. It is
shippedcomplete ready for use.
TYPE OF GASOLINE. Use a good
gradeof regular
gasoline.
TYPE OF OIL. Use a high gradeoutboard
oil, or,
if that is not available, regular SAE 30 motor oil.
Avoid use of low-priced third grade (ML) oils.
MD(TURE. Mix L/2 pint of oil with each gallon of
gasoline.
STRAIN Att FUEI
PROCEDURE. Pour into the container approximately
one-half the amount of gasoline required. Add all
the oil lequlred at the ratio of l/2 pint of oil to
each gallon of gasoline. Shake the two together
until they are thoroughly mixed. Add the balance of
gasoline. Shake container briskly to insure mixing.
LUBRICATION OF GEAR CASE. The gear case
has
been filled at the factory with the correct lubricant.
Check lubricant after first 5 hours of operation;
then every 50 hours. (Seepage 5.)
TAKE CARE OFYOURMOTOR
The service obtained from your motor ls dependent
largely upon the care it is given. Following the
simple suggestions llsted below will assist in its
proper maintenance.
1. Remove carburetor andgas tank strainer screens
and clean periodically.
2. Inspect
spark plugoccasionally,
clean
thoroughly,
wipe dry and adjust gap u necessary.
3. Check and adjust breaker points.
4. Draw up all nuts and screws at least once a
season.
5. Remove
grease
anddrain plugsperiodically, draln
off water if any and ftll with lubricant.
6. Wipe off motor regularly with a clean
oily cloth.

aOperatlon of Your Motor
BREAK.IN PERIOD
Reasonable care in the operatlon of the motor during
the first several hours of use will improve its per-
formance and insure Ionger life. Follow the oiling
instructions carefully, Do not run continuously atfull
speed for the first few hours, to give the rings and
bearings a chance to become well seated. The motor
may not develop full speed and power until after ap-
pro>dmately 20 hours operation. No extra oil is
required for the break-in period.
STARTING AND OPERATING INSTRUCTIONS
See Fig. 3.
1. Open air vent screw in fuel tank filler cap.
2. Open fuel shut-off valve under fuel tank.
3. Move speed control lever to position marked
START.
4. Turn carburetor knob to left or PRIME position
and hold down against spring pressure for 10seconds;
then release.
5. PulI starter handle slowly until starter engages,
then pull forcibly. If motor does not start after
several pulls, repedt priming instructions. Allow
starter cord to rewind before releasinghandle. Also,
do not pull cord out more than 30 inches-
6. After motor stalts, turn carburetor knob slowly
to right until motor runs smoothly. Advance speed
control lever as desired.
?. Advance speed eontrol lever to FAST position
and adjust carburetor knob until motor runs smoothly.
Since the speed control lever and carburetor control
are synchronized, the full range of speed is obtained
without further adjustment of the carburetor knob,
except when under unusual conditions.
8. To stop motor, move speed control Iever to
position marked STOP or beyond.
NOTE
The above starting instructlons are given in
step by step form - it is advisable to become
familiar with each detail prior to actually
operating the motor. A few moments spent
in practice are well worth while.

WARIYI MOTOR
It is not necessary to prime motor when starting i-f
motor has be-en warmed up. Motor can usually be
started with carburetor knob in running position
and pulling starter handle with speed control lever
at START position.
FIOODING
Flooding may occur by over-priming or priming a
warm motor. If this occurs, turn carburetor knob
to extreme right (Iean posltton) and pull starter
handle several times. When motor starts, allow to
run until it stops. Then follow instructions for start-
ing cold or warm motor, whichever applies.
REVERSE
An important feature of the motor is that it can be
turned completely around in its pivot bearing, per-
mitting backing up and easy maneuverability. To
reverse, simply raise the steering handle and turn
the motor around to REVERSE position. With the
motor in reverse position, the reverse lock (Fig.
4) prevents the thrust of the propeller from forclng
the lower unit out of the water. The reverse lock
should be kept lubricated with grease and checked
periodically for proper operation. For SAFETY SAKE
do not attempt to reverse motor at any speed higher
than haU throttle.

PROPELTER
Motors are equipped wlth a propeller which gives
the best all around performance on the average boat.
Adding a high speed propeller to a motor will not
increase the speed of the boat unless the boat itself
is light and designed to develop higher speed. We
cannot be responsible lor wear or damage to a motor
used for racing or equipped with a raclng propeiler.
PROPELLERSHEAR
PIN
Il the propeller strikes an obstruction, a shear pin
in the propeller shaJt may shear off, preventing
damage to propeller, gears or shaft. When the
pin shears the motor will suddenly speed, but pro-
peller will not turn. SHUT OFF MOTOR IMMEDI-
ATELY. Remove cotter pin, propeller shalt nut, and
slip oll propeller. Remove broken pin from propeller
shaft and replace with new shearpin. Reassembleand
tighten nut- firmly against propeller but not tight
enough to partially shear the pin. Replace cotter pln.
THECO.PIIOT
The co-pilot permits the motor to maintalna set
course without holding the steering haldle. It can
be adjusted by tighteningthe screw, located under
front of pivotbearing(Fig. 4) to the desired tenslon.
TILTING FRICTION
To adjust tilting frlction, ttghtenor loosennut (Fig.
4) on side of stern bracket to desired tension. Ten-
sion should not be too great, but only enoughto
maintain motor tn a tilt position. Never tilt motor
by using steering handle. Grasp rear of tank at
sides, thentilt.
EMERGENCY
STARTING
In case of starter failure. vou can still use your
motor.
Remove the screws holdtng starter housing to fuel
tank. Lift off entire starter housing assembly.
To start the motor, wind a 3/16-lnch rope wlth a

flywheel. Start motor in theusual.manner. (Fig. 5.)
When replacing the starter housing assembly, set
ln position and start the mounting screws. Hold-
ing starter in posltlon, pull handle slowly untll
starter engages. Tighten screws and agaln check

CARR.YINGHANDLE
The carrying handle ls a part of the steering
handle. To use, ralse handlegrip sllghtly, press
spring loaded steering handle lock (Fig.4) and
push handle all the way down. Release lock and
handle will automatically lock in position. To
again use as steering l'.-.irl'c, press lock and raise

CARBURETOR
ADJUSTTIIENT
The carburetor ls adjusted for both htgh and low
speed operation at the factory. If further adjust-
ment is necessary proeeed as follows: Wtth port
motor cover removed, start motor as previously
lnstructed, and operate at FAST, adjust carburetor
knob untll motor runs smoothly. Now move speed
control lever to SLOW. Turn low speed adjusting
screw, located on right handside of carburetor (Fig.
7) toward RICH or LEAN untll satisfactory low speed
performance is obtained.
NOTE: Turning low speed adJustlng screw or car-
buretor knob to the left enriches the mlxture, that
ls, lncreases the ratlo of fuel to air. Turning to
the rtght leans the mlxture, reducing the ratio of
fuel to air. A rich mlxture may cause motor to
run "rough" and a lean mixture is tndtcated by
"coughlng" or "spltting" ln the carburetor.
The carburetor ls now adjusted for average condi-
tlons. Spectal settlng may be necessary for best
performance wlth heavy boat loads or very slow
trolling.
RUNNING MOTOR IN TESTTANK
1. Do not run motor out of water.
2. Do not "break-in" motor ln tank.
3. When running ln tank be sure gear houslng and
propeller are submerged.
4. Do not race motor in tank.
5. Use test propeller when testing motor in tank.
6. Cavttatlon (air pocket around propeller) may oc-
cur when operatlng motor ln tank with regular pro-
peller. Motor will then not perform properly or it
may race and be damaged as a result,

CARN OF
CARE OF TTOTOR IN COI.D WEATHER
The motor will not freeze while in use, but when
lt is idle, water in the cyltnder or pump might
freeze and damage the motor. Drain by setting
the motor in an upright position and revolving the
flywheel with speed control lever in STOp positlon.
If the motor is to be stored durlng cold weather,
be sure t}tat no water ls left ln the motor or lt
may freeze. (See
"Storlng Your Motor.")
SALT WATER INSTRUCTIONS
When using a motor in salt water it should be re-
moved from the boat when not in service. Flush
the motor thoroughly elther by running tt ln a tank
of fresh water or by removing WATER FLUSH pLUG
(fg. 6) in gear houslng and, uslng an adapter,
(availabletltrough
your regular Service parts Source)
,
run fresh water through cooling system. Wipe the
motor dry and go over all parts wtth an oily cloth.
Thls should be done as soon as possible after re-
movlng motor from boat.
STORING YOUR TTOTOR
No outboard motor shouldbe placed in storage with-
out conslderlng the necessary precautions.
PREPARATIONFOR STORAGE
Remove all plugs in the gear case housing, (Flg.
6) to allow water (lf any) fn the gear case andwater

GEAR TUBRICATION
Keep gear housing
filled with grease at all times.
To fill, remove grease plug in right side of gear
housing and also drain screw on opposite side (Fig.
6). Do not lose washers on each. Insert grease
through plug hole until grease comes out of drain
screw hole. Replace screw and
plug securely. We
recommend a good grade outboard gear grease. Do
not use automotive differential or cup grease.
COOTING SYSTEfrT
This motor is water cooled. Water enters through
two holes in the propeller hub and into the positive
action rotary water pump located directly back of
the propeller (see flg. 6). The water is circulated
through tubes to the cylinder jacket ancl expelled
'from the motor through exhaust relief slots in rear
ef lower unit above the water line.
NOTE
When motor is in operation, periodically
check water pump operatlon by noting whether
water is expelled as explained above. If no
water is expelled or motor heats abnormally
it may indicate worn pump parts or clogged
intake in propeller or pump cap.
SPARK PIUG
The correct spark plug gap is .030 inch. The plug
is set properly at the factory and is rlght when
the
motor is received. We recommend ChampionJ6J
Care of Your Motor
spark plug, or equivalent for replacement. Keep the
spark plug cable free from oil and do not permit
it to become frayed or broken. Clean the spark
plug periodtcally andreset to the proper gap setting.
CAREURETOR.
ADJUSTINGNEEDLE
FR,ICTION
Should the carburetor adjustlng needle become so
loose that the carburetor knob will not remaln ln a
set position, lt can be ttghtenedby drawing down on
the packlng nut (Fie. 7). If ttghtening of the pack-
ing nut will not help, it may be necessary to re-
place the packing. To replace packing, remove the
carburetor knob, motor covers, primer cam, ad-
justing needle, packlng nut, washer, packtng and
spacer. Install new packing and reassemble. Be
sure all of old packing is removed before inserttng
new.
NOTE
Turn carburetor knob to "Prlme" posltlon
when tightening packlng nut to prevent damage
to needle seat.
'VIOTORSTHAT HAVE BEEN SUBMERGED
Precaution should be taken to prevent a motor go-
ing overboard (see paCe 1). However, lf a motor
has been submerged, tt should be recovered as
quickly as possible.
Since the motor ls temporartly out of working order,
do not attempt to operate it untll the followtng pro-
cedure has been used to restore it to servlce.

The above lnstructions are prlmarlly for motors that
have been submerged ln fresh water. For motors
submerged ln salt water a few additlonalprecautions,
llsted belowr ray be necessary.
1. Remove carburetor and fuel tank, and wash wtth
fresh water. Dry thoroughly.
2. Remove flywheel, and wash magneto wlth fresh
water.
3. It is advtsable to wash external working parts,
such as tle starter mechanlsm. wlth fresh water
and lubrlcate. Internal worklng parts are lubricated
by the fuel mlxture.
If by followlng the above instructlons, motor wlll
not operate, dlsassemble and wtpe all parts dry.
Coat wlth oil to prevent rust and follow instructions
under I'How to Obtain Service." (Seeback cover.)
frTAGNETO
It may be necessary occasionally to inspect the mag-
neto. If so, lt is necessary to remove the starter
housing, side covers, gas tank andflywheel. IIow-
ever, lf cleaning or adjustlng of points only is re-
quired, remove the starter houslng, (see page 3,
"Emergency Starting") and the three screws releas-
ing the starter ratchet and flywheel cover. Access
to the points for cleanlng or adjusting ts posslble
through the openlng on the top of the flywheel.
When adjusting points use the openlng in the flywheel
which ls farthest from the emergency startlng rope
notch on rlm of flywheel.
HOW TO RE'IIOVE TIYWHEEI
Remove motor covers, disconnect fuel line, and
remove fuel tank. Hold flywheel rigid and unscrew
the flywheel nut about two full turns. Have some-
one llft up on the flywheel and then place a plece
of bar solder or a block of lead over the flywheel
nut and tap a sharp blow with a hammer. B fly-
wheel does not come off, loosen nut a trlfle more
and repeat procedure.
When flywheel comes off, use care not to lose the
key by whlch the flywheel is held ln engagementwtttr
the shaJt. When agaln replaclng flywheel, be sure
key is in place and ftts snugly, then draw up the
nut as ttght as posslble. Use a hammer on the
wrench to insure good tightening.

'NAGNETO LUBRICATION
The magneto ls equlpped with a felt oiler to lubri-
cate the cirm and reduce wear on the cam block of
the breaker (Fig. 8). A few drops of light oil should
be put on the felt once or twice a year.
CIEAN AND ADJUST BREAKER
POINTS
After removlng starter ratchet and flywheel cover,
revolve flywheel until openingts directly over break-
er. Carefully spread points with small screwdriver.
Insert'point dresser. (Sandpaper,ftne coil file, nail
file, etc. NEVER USE EMERY CLOTH.) Release
points, work dresser up and down to smooth. For,-
low same procedure with piece of thlck snroothpaper
to remove traces of foreigrr particles whlch might
be left on points.
AIter cleaning, reset point gap to .020 inch maxi-
mum opening as follows: When hole in flywheel ls
directly over the breaker, maxlmum opening of the
breaker ls obtained. When adjusting polnts use the
opening in the flywheel which is farthest from the
emergency starting rope notch on rim of flywheel.
Check with .020 lnch feeler gage. If openlngls under
or over .020 tnch, loosenbreaker plate screw (ltem
5, Flg. 8) sliglltly. Turn adjusting screw (item 3,
Fig. 8) to right or left until required setting is
obtained. Tlghten breaker plate screw andre-check
with gage.
CARBURETOR(See
Fis. 9.)
It ls important that the carburetor be kept clean.
Dlrt, sedlment or water may accumulate in the
carburetor and cause hard starttng or irregular
performance.
Care of Your Motor
To clean the carburetor and reed valve, disconnect
the fuel line, and remove two nuts and lockwashers
which attach the carburetor to the crankcase. Re-
move the carburetor carefully to prevent damage to
the -gasket between crankcase and carburetor. If
the gasket is damaged, replace it with a new one.
Check the reed valve carefully for dirt betweenthe
lower reed andreed plate, or for damaged
reed. Re-
rnove the float bowl drain plug and screen. Remove
the float bowl cover. Flush out the float bowl and
entire carburetor including the strainer screen. Re-
move adjusting needle and blow out fuel passage with
compressed
air. (See
ltem ?, Fig. 9.)
Reassemble and lnstall the carburetor on thegtotor.
Be sure gasket is ln good condiHon and ls in place
to form an air tlght seal. When lnstalling gasket,
be sure side of gasket with small hole is at top to
line up with drain hole in crankcase andcarburetor.
After reassembllng carburetor wlth exception of
carburetor knob and primer cam and attachlng to
Motor, it is necessary to make initial adjustment of
the adjusting needle before installtng carburetor knob
or fastenlng primer cam to a{iusting needle. T\rn

POWER HEAD. The entire power head of this motor is lubricated by oil mixed
with the gasoline. It is important therefore to be sure the correct oil is used
and that it is properly mixed. (See
page 1.)
We recommend Mobiloil Outboard, or other good grade outboardoil, or a regu-
lar SAE 30 gra.de automotive enline oil. Avoid use of low price third grade
(ML) oils.
:::::::::=
GEAR CASE. The gear case of t}ris motor is filled at the factory with gear:::::::::=
grease for lubrication of gears and bearings. We recommend Outboard Mobile i€=
Grease for best results. Do not use Automotlve differential or cup grease. ;!!!j!!!]]
