MAINTENANCE
2. LUBRICATION_GEAR HOUSING
a. The Gear Housing has been pre-lubricated al
the factory; h0wevec ihe grease level should
be checked as follows using SAE 90 out-
board motor grease, (See Figure 2).
11) Prioi" to initial operation;
_ (2) After first four {4) hOurs of use.
13) Recheck after every flfty _t6Ol hou,s
il; '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,
(3} The outboard motor shoutd L
mounted on a stand vertically wit
power head up for storage,
(4) Pull starter handle si0wly until resis
ance ;s felt due to compression pre
sure, ther, stop. Release starter tensio
srowly tO prevent englne frorr; rever_
pressurL, i 'This t_osition will close bet

(6) Wipe exterior completely with ires
b. To Check, Drain or Fill gear housing, foUow , water cloth and then apply light coa"
these steps:
{1) Position outboard motor upright,
(2) Remove drain plug and washec 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, remb;,/e cotter pin, propeller and
shear pin from propeller shaft, also,
gear housing covet by unscrewing 2
bolts.
(6) When lubricant has completely drained,
replace parts and refill gear housing
using f_ll_ng procedure above•
For best results, lubricate propeller .shaft
with Hthium grease every 30 to 60 days,

3. MUFFLER INSPECTION
a, Periodically remove _ufflor cover by un-
screwing screws and inspect- for car_on
build-up inside the muffler inlet and outlet,
the exhaust port and= the combustion
chamber of the cylinder, Excessive carbon
witl prevent drawing the maximum power
out of the engine. (See Figure 3).
b, Care should be exercised while cleaning
awav carbon to prevent-scratches to the
surface of the engine components and dro_-
ping carbo_ inside of crankcase.
:ing of oil,
b+ When starting a new season, always use fres
gasoline, Last year's gasoline may hay
varnish deposits that will plug the carl_.
refer jets, thus requiring a complete ove_
haul,
c. To plan for the coming season; we recorr
mend you contact ,,,our Sears Serv.c
Center before the new season for any servJc
repair work required.
OPERATION
5.
a,
NEW AUTOMATIC CLUTCH
New automatic clutch. Based on a du_
centrifugal clutch des=gn, it altows the out
board prop to turn at very slow speeds o
even come to acomplete stop while th
engine contimJes operating efficiently, I
eliminates the need to shift gears by han_
and prevents tl_e engine from overheatin,
and stalling at slow speeds.
When engine slarls, molar msneutral. A
throttle increases, sub c_ulch engages. A
appx, 6 MPH. main clutch engages t=
provide direct drive for cruising,
