h. Check oil pressure gauge for op-
eration of oil pump.
If gauge does
not indicate oil pressure, stop en-
gine.
Table
4
gives
proper
oil
pressure for each model engine.
CAUTION
Do not race
engine
with
clutch
disengaged
at any
time.
Racing
a cold
engine will cause
exces-
sive wear and may seriously dam-
age engine. New motors should
be
run at
one-half .throttle for
a
period of 15 hours.
NOTE
If the engine temperature is con-
trolled
with
a
manual
by-pass
valve as shown in
Fig. 11, water
\iill issue
froD the exbaust pipe
as soon as the pump has primed and
the engine filled with water.
If
tile engine temperature is controlled
by thermostat,
only a trickle of
water will issue from the exhaust
pipe until the engine reaches its
normal operating
temperature and
the thermostat opens to dump water
overboard.
3. STOPPING THE ENGINE
The speed
of your
boat
should be
gradually
reduced
while
you
are
still some distance
from the moor-
ing
or landing.
Before
stopping
the engine, close
the throttle and
disengage the clutch. Allow the en-
gine to idle for a minute or so be-
fore
turning
off
the
ignition.
Stopping in this manner will permit
excessive
heat to
be
absorbed by
the cooling system.

BREAK-IN
Your UNIVERSAL
engine was
run and
tested for six hours
on one of our
test stands with electric dynamome-
ter.
It was
adjusted and
checked
for maximum
power at
rated speed.
However, those adjustments were cor-
rect
only for
the prevailing
at-
mospheric conditions and fuel used.
You
may
find
it
necessary
to
slightly readjust the carburetor and
igni t ion timing for peak per formance
-34-
in your locality
and with the fuel
available.
If readjustment
is at-
tempted it should be done by a com-
petent mechanic.
The engine
will not be
thoroughly
broken
in until
approximately
35
hours
of operation
have
been at-
tained.
DO
NOT
CONTINUOUSLY
RUN
YOUR
ENGINE OVER
2000 RPM
DURING
THIS PERIOD AND AVOID
LONG PERIODS
OF SLOW IDLING. OCCASIONALLY DURING
BREAK-IN YOU :MAY RUN
THE ENGINE AT
FULL THROTTLE
BUT NOT
FREQUENTLY
OR FOR
PERIODS OVER ONE
MINUTE IN
DURATION. ALWAYS WARM UP THE ENGINE
BEFORE ANY RUN.

STARTING FUEL OIL-KEROSENE MODELS
a. Start engine on gasoline as des-
cribed in Paragraph 2.
b. Allow engine to run for a period
of 3 to 5
minutes to
allow it
to
reach proper
operating temperature
of 130 to 180 degrees.
c. Switch over to fuel oil by turn-
ing the three-way cock,
located in
the fuel line, to the proper posi-
tion.
