MAINTENANCE
2. LUBRICATION _GEAR HOUSING
a, The Gear Housing has been pie-lubricated 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 b,
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 c.
is tightened securely.
(5) To achieve complete drainage of lub_'i_
cant, remove cotter pin, propeller and' -,:_-_
shear pin from propeller shaft, also,
gear housing cover by unscrewing 2
bolts,
(6) When lubricant has completely clrained.
replace ;)arts and refill gear housing 5.
using filling procedure above. a.
c. For best results, 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 maximum power
out of the engine. (See Figure 3).
b. Care should be exercised while cleaning :=_ =
away carbon to prevent scratches to the
su rface of the engine components and drop.
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.

boat, allow all water to drain from
unit.
(2) When Pemoving outboard motor from
boat, allow all water to drain from
unit. " ......
(3) The outboard motor should be
mounted on astand vertically with
power head up for storage,
(4) Pull starter handle slowly until resist-
ance is felt due to compression Pie s;
sure, then stop. Release stsrter tension

the intake and exhaust ports for
storage.
{5) Drain and fill gear housing as outlined
under Lubrication Of Gear Housing,
(Ref. 2)
|6} Wipe exterior completely with fresh
water cloth and then apply light coat*
ing of oil.
When starting anew season, always use fresh
gasoline. Last year's gasoline may have
varnish deposits that will plug the carbu-
retor jets, thus requiring acomplete over-
haul,
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
NEW AUTOMATIC CLUTCH
New automatic clutch. Based on adual
centrifugal clutch design, it allows the out.
board prop to turn at very slOW speeds or
even come to a complete stop while the
engine continues operating efficiently, It
eliminates the need to shift gears by hand
and prevents the engine from overheating
and Stalling at slow speeds.
When engine starts, motor is neutral. As
throttle increases, sub clutch engages. At
approx. 6 MPH, main clutch engages to
provide direct drive for cruising,
