MAINTENANCE
2. LUBRICATION _ GEAR HOUSING
a. The Gear Housing hasbeen pre-lubricated at
the factory; however, the grease level should
be checked as follows using SAE 90 out-
board motor grease, tSee 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 |ubdcant 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 cotter pin, propeller and
shear pin from propeller shaft; also_
gear housing cover by Unscrewing 2
bolts,
(6) When lubricant has completely _ra_ned,
repJace parts and refill gear housing
using filling procedure above,
c. For best results, lubricate propeller shaft
with tithium grease every 30 to 60 days.
3. MUFFLER INSPECTION
a. Periodically remove '_miJffler cover- by un-
screwing screws and inspect for carbon
build-up ins_i.dethe muffler inlet and outlet,
the exhaust port andi: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:i scratches to the
surface of the engine components and drop-
ping carbon inside of crankcase.
(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
slowiy to prevent engine from revers-
ing rotation due to compression
pressure, This position will close both.
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,
b. When starting a new season, always use fresh
gasoline. Last year's gasoline may have
varnish deposits that will 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
NEW AUTOMATIC CLUTCH
New automatic clutch. Based on a dual
centrifugal clutch design, it allows the out-
board prop to turn at very sJow 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 ehgages to
provide direct drive for cruising.
4. PROLONGED STORAGE
a. Tot store your= outboard- motor for pro=
longed ,storage, prepare outboard as fol-
lows:
(1) ' See paragraph on stopping procedures.
(Ref. 10) ' '
(2) When removing outboard motor from
boat, a_tow all water to drain from
unit.
