MAINTENANCE
2. LUBRICATION-- GEAR HOUSING
a. The Gear Rousing has been pro-lubricated at
the factory, however, the grease level shoutd
be checked as follows using SAE 90 out-
hoard motor grease (See Figure 2)
(lJ Prior to initial operation
(2) After first four (4J 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
_s _mportant, 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 dram plug and washer, then
insert nozzle of gear lubricant tube
_nto hole.
(3) Squeeze tube untd lubricant is forced
Out around tube.
{4) Replace plug and washer. Be sure plug
is t_ghtened securely.
(5) To achieve complete drainage of lubri-
cant, remove cotter pin, propeller and
shea_ pin from propeller shaft, also,
gear housing cover by un_rewmg 2
bolts.
(6} When lubricant has compretely drained,
replace parts and refill gear housing
using filling procedure above.
c. For best results, lubricate propelrer shaft
w_th lithium grease every 30 to 60 days.
3. MUFFLER INSPECTION
a. Periodically remove muffler covet 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 cyhnder. Excessive carbon
w_ll 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
surface of the engine components and drop-
ping carbon ms,de of crankcase.
b_
c,
(3) The outboard motor should be
mounted on astand vertically with
power head up for storage
(4) Pull starter handle slowly untd 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 will close both
the retake 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-
mg of o_1.
When starting a new season, always use fresh
gasoline. Last year's gasoline may have
varnish deposits that wdl plug the carbu-
retor jets, thus requiring a complete over-
hau I
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
5.
a.
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 whde the
engine continues operating effimently. It
ehminates the need to shift gears by hand
and prevents the engine from overheating
and stalhng at slow speeds
When engine starts, motor _s neutral As
throttle increases, sub clutch engages. At
appx. 6 MPH, mare clutch engages to
provide dtrect drive for cruistng.
4. PROLONGED STORAGE
aTo 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, allow all water to dram from
unlt.
