Owner's Responsibility and Operating Safety Check List
• i'_: ¸•••
BE SURE TO READ AND DO THE FOLLOWING BEFORE
OPERATING YOUR OUTBOARD MOTOR
SAFETY CHECK LIST
1. Learn and observe the boating laws of the U.S, Coast Guard, state, iocat author_
ities. ;
2. U.S. Coast Guard regulations require the following:
a. Provide an approved life-vest, type 1,2 or 3, Personal Flotation Device for each
person in boat. (Encourage passengers to Wear them,)
b. If the boat exceeds 16 feet, also carry a type 4, throwable Personal Flotation
Device,
3. Do not fill fuel tank with motor running or near any flame or lighted smoking
material.
4. When loading boat distribute the load evenly; keep the toad tow; don't overload;
don't stand in a small boat. Take weather and water conditions into account.
S, Do not permit persons to ride on parts of the boat Hot designed for such use
Standing, bow riding and seat back or gunwale riding can be especially dangerous.
OWNER'S RESPONSIBILITY
6. Read owner's manual before running your new outboard motor,
7, Before starting, make sure your motor is securely mounted to boat transom with a
safety chain, Tighten clamp stud handles securely by hand,
8, Be sure to have pliers, screwdriver, spare spark ptugs, wrench, shear pins and cotter
pins in boat whenever leaving Shore.
9. :Be sure to have an adequate supply of fuel lcarry only in an approved container} on
board. Use agood grade of regular gasoline with proper mixture, as cited in the
Specifications.
I0. Occasionally check to be sure clamp stud handles on transom mounting bracket are
tight.
11, IN CASE OF AN EMERGENCY, THE ENGINE CAN BE STOPPED BY DEPRES-
SING THE STOP BUTTON OR PLACING CHOKE KNOB IN FULL CHOKE
POSITION, =
12. Keep an alert lookout. Serious accidents have resulted from failure to use eyes,
13, Keep firefighting and lifesaving equipment in good condition and readily accessible
at all times,
14, Good housekeeping is even more important afloat than ashore. Cleanliness dimin-
ishes the probability of fire and tripping hazards,
TIPS FOR TRAILERING OR AUXILIARY USE
15. When launching or loading boat on a trailer, place your outboard motor in the
tilted storage position, Also when trailering your boat and outboard motor, keep
outboard motor in upright (vertical) position on the boat transom. Outboard
motors transported across rough roads in the "tilt" position could cause transom
damage or mounting brackets to break off, toeing your motor. If motor must be
trailered in "tilt" position, ashort length of 2x4should be placed between the
motor bracket and the motor leg. The motor leg should then be firmly tied down
against the 2x4to prevent any possible damage, Similar Precautions should be
taken if using the motor as an auxiliary power source for asailboat or power boat.
When using motor as an auxiliary power source, the use of an auxiliary adjustable
position motor bracket is recommended.

MAINTENANCE
1. FEATURE INFORMATION
a. This outboard motor has special design
features as shown in Figur:e 1,
b, Your seJection of our Marine Products will
provide_you with many hours of enjoyable
boating. To assure your, complete satisfac-
tion on the investment you have just made,
we ask you to read this manual thoroughly
before going afloat, Acquaint yourself with
the particular areas of operation on your
outboard motor as you read the step-by-step
procedures. Keep in mind maximum per-
formance is achieved only when the owner
or operator is completely familiar with the
operating instructions.
:, Periodic servicing will be required, It is
recommended that you consult your Sears
Service Center when service is necessary.
We will be happy to extend our facilities
and assure prompt service. .,
2. LUBRICATION --_GEAR HOUSING
a, The Gear Housing has been pre-iubricated at
the factory; however, the grease level should =-
be checked as follows using SAE 90 out-
board motor grease. (See Figure 2).
(1) Prior to initial operation.
(2) After first four (4) hours of use.
(3) Recheck after every fifty (50) hours
running time.
(4) Replace with new lubricant at the end
of your outboard motor season. This
• is important, as it removes any water
from the gear housing .and prevents-
possible corrosion to internal parts•
b. TO Check, Drain or Fill gear housing, follow:-
these steps:
(1) Position outboard motor upright.
(2) Remove drain plug and washer, then
insert nozzle of gear lubricant tube:
into hole,
(3) Squeeze tube until lubricant is forced
out around tube.
(4) Replace plug and washer. Be sure plug
is tightened securely,
(5) To achieve complete drainage of lubri-
cant, remove cotte[ pin, propeller and
shea= pin from propeller shaft, also,
gear housing cover by unscrewing 2
bolts.
(6} When lubricant has completely drained,
reptace parts and refilJ gear housing
using filling procedure above.
_. For best resutts, lubricate propeller shaft
with lithium grease every 30 to 60 days.
3, MUFFLER INSPECTION
a, Periodically remove muffler cover by un-
screwing screws and inspect for carbon
build-up inside the muffler inlet and outlet,
the exhaust port and the combustion
chamber of the cylinder, Excessive carbon
will prevent drawing the rhaximum power_
outof the engine. (See Figure 3),
b..Care Should be-exercised white cleaning
away carbon to prevent scratches to the
surface of the engine components and dropL
ping carbon inside of crankcase,
4, PROLONGED STORAGE
a, TO store your outboard motor for pro-
longed Storage, prepare outboard as fol-
lows:
(1) See paragraph on stopping procedures.
(2) When removing outboard motor from
boat, aliow all water to drain from
unit,
(3) The outboard motor should be
mounted on a stand vertically with
power head up for storage,
(4) Pull starter handle slowly until resist-
ance is felt due to compression pres-
sure, then stop, Release starter tension
slowly to Prevent engine from revers-
ing rotation due to compression
pressure. This position wilt :close both
the intake and exhaust ports for
storage,
(5) Drain and fill gear housing as outlined
under Lubrication of Gear Housing.
(6) Wipe exterior completely with fresh
water cloth and then apply light coat-
ing of oil.
b. When starting a new season, always use fresh
gasoline, Last year's gasoline may have
varnish deposits that wilt plug the carbu-
retor jets, thus requiring a complete over-
haul.
c. To plan for the coming season, we recom-
mend you contact your Sears Service
Center before the new season for any service
repair work required.

OPERATION
_, BOAT MOUNTING
a. Mount the motor on the center of the boat
transom {stern). (See Figure 4),
CAUTION
Hand tighten clamp bracket clamp stud
h0nd!_ _imuit0ne0u_ly, Do not usea
wrench or any other device that would
cause damage to brackets, Occasionally
check to be sure lamp stud handles on
transom mounting bracket are tight,
(See Figure 5).
b. To obtain the best performance from your
outboard, the following boat transom speci-
fications are recommended: {See Figure 4),
Transom Angle (See View 3}:
............. 12 to 15 degrees
Transom Height (See view 4):
............ _ . .20.7 inches
c, The angle of the motor column is easily
adjusted by removing the Hitch Pin and
changing the Tilt Lock Bracket Pin in the
three (3) different angle- position holes
located on either side of the right or left
Transom Mounting Brackets. Each angle
position elevates five (5) degrees. Try
center hole position first. (See Figure 6).
d. To find the cot(act angle position, make a
test Pun at full throttle with your usual
loading in the boat. Always stop motor to
change the Tilt Lock Bracket Pin, The cor-
rect angle position wil{ have your boat
traveling with the bow slightly higher than
the stern, but should not porpoise {bow
rises and falls rapidly and continuously): Be
sure Tilt Lock Bracket Pin is always pushed
completely through both Transom Mount-
ing Brackets and Hitch Pin is secured.'
WARNING
If the motor column is tiited too far out-
ward, the boat is likely to porpoise or
cavitate at full throttle, which can be
dangerous because a cross wind or a wave
could suddenly deflect the boat into a
dangerous turn. Als0, if the motor
column is tilted too far inward, the bow
of the boat will dig in, which can be
dangerous when crossing a wake or in
rough water. Do not run motor in the
storage position. (See View t and 2,
Figure 4).

SYSTEM
The magneto ignition system consists of the
following component parts: Contact Points,
Condenser, and Ignition Coil. (See Figure
13).
Inspect the following if engine fails or is
hard to start:
(1) Spark plug as often as necessary. Be
sure spark plug gap: setting is .025"
(0.Atom).
(2) Gasoline fuel supply and fuel shut,
off valve should be open.
(3) Carburetor being starved of fuel. '!
The correct spark plug for this motor is
Champion RCJ_8.
•To test ignition system, remove spark
plug and place against bare spot on metal =
part of motor away from: cylinder spark
plug hole and then pull starter cord several
Figure 14
times, If a Spark bridges the plug gap, the Figure [4A

:formations in the _carburetor during
storage:
1. Close fuel shut-off valve and air vent
screw at fuel filler cap.
2. Allow motor to run at idling speed

cating the carburetor has run dry, '
4. REMOVING MOTOR FROM BOAT " "
.Always tilt motor by lifting on rear of
shroud. DO NOT PUSH DOWN ON THE
STEERING HANDLE. When removing the
motor from the boat, raise the outboard in
upward direction until the propeller clears
the transom. Hold the motor upright long
enough ,to allow all water to drain from the
exhaust pipe. When you find it difficult to
hold the motor upright, tighten the Center
8oil increasingly for desired effort. (See
Figure 14).
WARNING
Although the engine is air cooled, it is
possible to burn your hands on the engine
block and upper portion of the column.
Do not touch,
it may be necessary to rotate the motor tO
one side before tilting the motor on the
transom to remove leg from the water when e.
installed on boats with thick transoms,
Always carry outboard with the engine
above the lower unit to prevent moisture
from entering the engine through the
exhaust ports, f.
Steering handle serves as car_/ing handle as
shown in Figure 14A.
15, SALT WATER OPERATION
To materlally,increase the life of all exposed
• parts and decorative finishes, fo]10w :the step s
indicated below.
a, Always tilt your motor out of the water
when not in use.
b. Never leave the lower unit in salt water
oyernight,
c. Wipe exterior completely with fresh water
cloth and then apply light coating of oil,'
d, Lubricate propeller shaft occasionally with
a waterproof type of lubricant (Lithium
Grease), thus enabling the propeller to be
removed easily,
_t is go0c{ practice when operating _n salt
water to inspect your motor daily and to
apply alight coating of grease to any
part or area that shows evidence of cor-
rosion or rust,
Always remove motor from boat ver-
tically, allowing water to drain from column
before tilting the motor,
