OPERATION OF YOUN MOTON
ATTACHING N'IOTORTO BOAT
This motor is designed
for use on a standard 15inch
transom. lf transom ls higher, it shouldbe cut down
to 15 inches so propeller wlll be at least 2 lnches
below bottom of boat. Best performance will be ob-
tained only by having the drlveshaft vertlcal andthe
propeller placed beiow bottom of the boat. If the
above instructions are followed, the lowerunltshould
clear the bottom of the boat when
the motor is turned
to reverse positlon: however, someboats
may be so
constructed that the keel will have to be modifled
for clearance.
Place motor on stern of boat wtth stern bracket
clamps inside the sterh, centered on the transom
or stern board. Tighten bracket clamp screws se-
curely by hand. Adjust lower unit angle by tilting
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 runnlng
(see
Ftg. 2).
When motor is running, occasionally check
bracket clamp screws to be sure they are
ttght. 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 attached to motor
stern bracket and boat will guard against loss of
motor overboard. Holes are provlded in thumb
screw handles through whlch a padlock may be ap-
plied to tock the motor on the boat. (See Fig. 4.)
TUBRICATION AND FUEL INSTRUCTIONs
Proper lubricatlon is an important factor in the per-
formance and Iife of your outboard motor. The
following lnstructions are therefore very important
and should be lollowed carefullv.
IfrIPORTANT
The oil and fuel mixture referred to in the following :-
instructlons should always be. thoroughly mlxed ln ==
a separate container before pouring into motor fuel YJI
tank: NEVER POUR SEPARATELY INTO FUEL :::
TANK. AIso, all fuel shouldbe poured through'a :
fine mesh strainer to remove dirt and water \,vhich:':=
may be present. Use olly metal containers. :=
TYPE OF GASOLINE. Use a goodgrade of regular
gasoline.
TYPE OF OIL. Use a good grade of S.A.E. 30
straight mineral oil such as outboardmotor ' marine
or a comparable grade; or a regular (not premlum)
type of motor oll. See back cover of this manual
for correct oll speclfications.
MDnURE. Mix l/2 plnt of oil nrith each gallon of
gasoline.
STRAIN Att FUEL
PROCEDURE. Pour lnto the container approximately
one-half the amount of gasoline requlred. Add all
the oil requlred at the rafio of l/2 plnt 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 midng.
LUBRICATION OF GEAR CASE. The gear case has
been filled at the factory wlth the correct lubricant.
Check for lubricant aJter 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
simply 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 tf necessary.
3. Check and adjust breaker polnts.
4. Draw up all nuts and screws at least once a
season.
5. Removegrease anddrain plugsperlodtcally, drain
off water if any and fill with lubricant.
6. Wipe off motor regularly with a clean oily cloth.
?. Remove propeller perlodically to lnspect shear

BREAK.IN PERIOD
Reasonable care ln the operatlon of the motor during
the first several hours of use wlll lmprove lts per-
formance and insure longer life. Follow the oiling
instructions galsfrrlly. Do not run continuouslyatfull
speed for the first few hours, to give the rlngs and
bearings a chance
to becomewell seated. The motor
may not develop full speed and power until after ap-
prodmately 20 hours operatlon. No extra oil ls
required for the break-in period.
STARTING AND OPERATING INSTRUCTIONS
See
Ftg. 3.
1. Open air vent screw in fuel tank flller 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 pcsiHon
andhold downagainst spring pressure for l0secondsl
t}ten release.
5. Pull starter handle slowly until starter engages,
then pull forcibiy. If motor does not start after
several pulls, repeat priming instructlons. Allow
starter cord to rewind before releaslnghandle. AIso,
do not pull cord out more than 30 inches.
6. After motor starts, turn carburetor knob slowly
to right until motor runs smootily. Advance speed
control lever as desired.
?. Advance speed control lever to FAST position
andadjust carburetor knob untll motor runs smoothly.
Since the speed control lever and carburetor control
are synchronized, the full range of speedis obtained
without further adjustment of the carburetor knob,
except when under unusual conditlons.
8. To stop motor, move speed control lever 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 weII worth while.
Operatlon of Your Motor
WARII MOTOR
It ts not necessary to prime motor whenstartlng if
motor has been warmed up. Motor can usually be
started with carburetor knob in runnlng position
and pulltng starter handle with speed control lever
at START position.
;IOODING
Floodtng may occur by over-primlng or priming a
warm motor. If this occurs, turn carburetor knob
to extreme rtght (lean posttlon) and pull starter
handle several times. When motor starts, allow to
run until it stops. Thenfollow instructions for start-
ing cold or y/arm motor, whichever applies.
REVERSE
An lmportant feature of the motor is that it can be
turned completely around in its pivot bearing., per-
mittlng backtng up and easy maneuverability. To
reverse, simply raise the steerlng handle and turn
the motor around to REVERSE position. With the
motor in reverse positlon, the reverse lock (Fig.
4) prevents the thrust of the propeller from forcing
the lower unlt out of the water. The reverse lock
should be kept lubricated with grease and checked
periodically forproperoperation. For SAFETY SAKE
do not attempt to reverse motor at any speedhigher
than half throttle.
Be careful not to strike submergedobstructlon
when in REVERSE - motor does not tilt
in reverse position.
REfiIOVING TTOTOR FROTI BOAT
When removing motor from boat, llft motor in a
straight upward position and hold this position for
a brief period until all water is drained frorr the
underwater exhaust tube and qater cooling system.
Do not stand motor on magneto or carry with the
magneto down before draining water, as this may
allow water to enter the powerhead from under-
water exhaust tube. Toward end of run, just before
stoppingmotor, close FUEL SHUT-OFF VALVE and
permlt motor to run until it stops, draining carbure-
tor. Close carburetor adjusting knob andvent screw
in filler cap. The motor can then be carried without
leakage. For complete safety, emptyfuel tank when
transporting motor.

Operatlon of Your Motor
PROPEttER
Motors are equipped wlth a propeller whlch glves
the best all around performance on the averageboat.
Adding a high speed propeller to a motor will not
lncrease the speed of the boat unless the boat ltself
is light and designed to develop htgher speed. We
cannot be responsible for wear or damage
to a motor
used for racing or equlppedwlth a raclng propeller.
PROPELLERSHIAR PIN
If the propeller strikes an obstructlon, a shear pin
in the propeller shaIt may shear off, preventlng
damage to propeller, gears or shaJt. When the
pin shears the motor will suddenly speed, but pro-
peller rvlll not turn. SHUT OFF MOTOR IMMEDI-
ATELY. Removecotter pin, propeller shaftnut, and
slip off propeller. Remove broken pin from propeller
shaft andreplace with newshearpln. Reassembleand
tighten nut firmly agalnst propeller but not ttght
enoughto partially shearthe pin. Replacecotterpln.
THE CO.PIIOT
The co-pilot permits the motor to maintaln a set
course wlthout holding the steering handle. It can
be adjusted by tlghtening the screw, located under
front of pivot bearing (Fig. 4) to the desired tension.
TIITING FRICTION
To adjust tilting friction, ttghten or loosennut (Ftg.
4) on side of stern bracket to desired tenslon. Ten-
slon should not be too grea.t, but only enoughto
maintaln motor ln a tilt position. Never tilt motor
by using steerlng handle. Grasp rear of tank at
sides, then tilt.
EMERGENCY
STARTING
In case of starter failure, you can still use your
motor.
Remove the screws holdlng starter housing to fuel
tank. Llft off entire starter housing assembly
.
To start the motor, wind a 3,16-inch rope wlth a
knot ln one end clockwlse on the pulley on top of the
flywheel. Start motor ln theusualmanner. (FfS. 5.)
When replacing the starter housing assembly, set
ln position and start the mounting screws. Hold-
tng starter in posltion, pull handle slowly untll
starter engages. Ttghten screws and agaln check
engagement.
CARRYINGHANDLE
The carrying handle ls a part of the steerlng
handle. To use, ralse handlegrip slightly, 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 handle, press lock and raise
handle
CARBURETOR
ADJUSTMENT
The carburetor ls adjusted for both hlgh and low
speed operation at the factory. If further adjust-
ment is necessary proceed as follows: Wlth port
motor cover removed, start motor as previously
lnstructed, and operate at FAST, adjustcarburetor
knob until motor runs smoothly. Now move speed
control lever to SLOW. Turn low speed adjusting
screw, located on rlght handstde of carburetor (Fig.
7) toward RICH or LEAN until satisfactory low speed
performance is obtained.
NOTE: Turning low speed adjusting screw or car-
buretor knob to the left enriches the mlxture, that
ls, increases the ratlo of fuel to air. Turnlng to
the rlght leans the mlxture, reducing the ratio of
fuel to air. A rich nlxture may cause motor to
run "rough" and a lean mlxture is !.ndicated by
"coughing" or "spltting" ln the carburetor.
The carburetor ls now adjusted for average condi-
tions. Speclal settlng may be necessary for best
performance wtth heavy boat loads or very slow
trolling.
RUNNING ftTOTORIN TESTTANK
1. Do not run motor out of water.
2. Do not "break-in" motor ln tank.
3. When running in tank be sure gear houslng and
propeller are submerged.
4. Dc not race motor in tank.
5. Use test propeller whentestlng motor in tank.
6. Cavltatton (air pocket around propeller) may ocr
cur .when operating motor ln tank with regular pro-
peller. Motor wtll then not perform properly or it
may race and be damaged as a result,

GEAR TUBRICATION
Keep gear housing filled with grease at all times.
To fill , remove grease plug in right stde of gear
housing and also draln screw on opposite side (Fig.
6). (Do not lose washers on each.) Insert grease
through plug hole until grease comes out of draln
screw hole. Replacescrew and plug securely. See
back cover of this manual for speciflcations of cor-
rect gear lubricant.
COOTING SYSTEM
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 Ffg. 6). The water is clrculated
through tubes to the cylinder jacket and expelled
from the motor through exhaust relief slots in rear
of lower unit above the water llne.
NOTE
When motor is ln operation, periodically
check water pump operation 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.
SPARKPIUG
The correct spark plug gap is .030 inch. The plug
is set properly at the factory and is rtght when
the
motor is received. We recommend Champion
J6J
spark plug, or equivalentfor replacement. Keep the
spark plug cable free from oll and do not permit
it to become frayed or broken. Clean the spark
plug periodlcally andreset to the proper gapsetting'

Should the carburetor adjusting needle become so
loose that the carburetor knob will not remain in a
set posltion, lt can be ttghtened
by drawing downon
the packlng nut (Fig. ?). 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, packing nut, washer, packing and
spacer. Install new packing and reassemble. Be

MOTORS THAT HAVE BEENSUBMERGED
Precaution should be taken to prevent a motor go-
ing overboard (see pa.ge
1). However, if a motor
has been submerged, it should be recovered as
quickly as possible.
Since the motor ls temporarlly out of worklng order,
do not attempt to operate it until the followlng pro-
cedure has been used to restore it to servlce.

and crank motor to remove yater from cyllnder
and crankcase.
3. Check spark by holding spark plug wire about
1/4 inch from cyllnder and cranklng motor raptdly.
4. Replace all parts removed, flll tank with newfuel
mlxture, and'start motor. It may be necessary to
clean water from polnts of spark plug several ilmes
as there is a posstbllity of small drops of water
remalning ln.the cylinder which may short the plug.
The abovelnstructlons are prlmarily for motors that
have been submerged tn fresh water. For morors
submerged in salt water a few addiilonalprecautions,
listed below, B&y be necessary.
l. Remove carburetor and fuel tank, and washwith
fresh water. Dry thoroughly.
2. Remove flywheel, and wash magneto wlth fresh
water.
3. It is advlsable to wash external working parts,
such as the starter mechanlsm, with fresh water
and lubrlcate. Internal working parts are lubrlcated
by the fuel mixture.
If by following the above instructions. motor will
not operate, disassemb_le
and wipe ali parts dry.
Coat with oil to prevenL rust andfollow instructions
under "How to Obtain Service." (Seeback cover.)
MAGNETO
It may be necessary occa,slonally to inspect the mag-
neto. If so, lt is necessary to remove the starter
houslng, side covers, gas tank andflywheel. Ilow-
ever, lf cleaning or adjusting of points only is re-
qulred, remove the starter houslng, (see page 3,
"Emergency Starting") and the three screws releas-
lng the starter ratchet and flywheel cover. Access
to the points for cleanlng or adjusting ls posslble
through the openlng on the top of the flywheel.
When adjusting points use the openlng in the flywheel
whlch is farthest from the emergency starttng rope
notch on rlm of flywheel.
HOW TO REfrIOVE FLYWHEEI
Remove motor covers, dlsconnect fuel line, and
remove fuel tank. Hold flywheel rigid and unscrew
the flywheel nut about two full turns. Ilave some-
one lift up on the flywheel and then place a ptece
of bar solder.or a block of lead over the flywheel
nut and tap a sharp blow udtlr a hammer. If fly-
wheel does not come off, loosen nut a trifle more
and repeat procedure.
When flywheel comes off, use care not to lose the
key by which the flywheel ls held in engagement wlth
the shaft. When agaln replaclng flywheel, be sure
key is in place and fits snugly, then draw up the
nut as tight as posslble. Use a hammer on the
wrench to insure good tlghtening.

CARBURETOR(See
Fig. 9.)
It is important that the carburetor be kept clean.
Dirt, sediment or water may accumulate in the
carburetor ald cause hard starting or irregular
performance.
To clean the carburetor and reed valve, dlsconnect
the fuel Une, and remove two nuts and Iockwashers
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 ls damaged, replace it vdth a new one.
Check the reed valve carefully for dirt between
the
lower reed andreed plate, or for damaged reed. Re-
move the float bowl draln plug and screen. Remove
the float bowl cover. Flush out the float bowl and
entire carburetor including the strainer screen. Re-
move adjusting needleandblow out fuel passage with
compressedair. (See Item ?, Fig. 9.)
Reassemble and tnstall the carburetor on the motor.
Be sure gasket is ln good condiHon and ls in place
to form an alr tight seal. When lnstalling gasket,
be sure side of gasket with small hole is at top to
Iine up with drain hole in crankcase andcarburetor.
After reassembling carburetor with exception of
carburetor knob and primer cam and attaching to
Motor, it ls necessary to make initial adjustment of
the adjusting needle before lnstalllng carburetor knob
or fastenlng primer cam to adjusting needle. Turn
