ENGINE BREAK-IN AND GENERAL RUNNING
1. Engine break-in period should be approximately 10 hours
of
operation at
75%
of
normal cruising
speed.
2.
On your trial cruise, check the propeller shaft for abnormal vibration and engine mounts for
tightness. Realignment
of
the
propeller shaft may be required
if
noticeable vibration is present.
Boat
should
be
in
the
water when checking alignment. Universal
is
not responsible for shaft align-
ment,
or
locking nuts on mounts coming loose.
3. After
the
break-in period, an average cruising speed for a sail boat installation is about
80%
of
the
maximum engine speed
obtainable,
to
achieve hull
speed.
4. Periodically check oil light indicators, ammeter, temperature and exhaust water for normal opera-
tion, this
is
the operators responsibility.
5. When shifting transmission, engine R.P.M.
should
be
reduced
to
idle, then shift transmission firm-
ly
from one direction
to
another. A slight pause in neutral will allow propeller
to
slow and add life
to
transmission. In adverse conditions due
to
winds, sea,
or
higher RPM's
it
may
be
more difficult
to
shift.
STOPPING THE ENGINE
1. Place throttle in
the
idle position.
2.
Place transmission shift lever in neutral. (Center position).
3. Leave engine idle for approximately 1
to
2 minutes
for
it
to
cool down.
4.
To
stop engine on early Models 15,
18,20,30
& 40, hold throttle lever in
the
back position
against
the
spring loading until
the
engine stops. Then release the throttle from the stop position
and throttle will return
to
the
idle position. Repeat
if
engine does not stop
the
first time. Models
M-12, M-25, M2-12, M3-20, M4-30, M-25XP,
M-35,
M-40,
M-SO
have a separate stop lever for shut-
ting
the
engine down. All newer models have a shut down lever on panel, pull
lever
to
stop engines, then
tum
off
key.
The
newer models have a separate shut down lever.
5.
Tum
key
to
the
"OFF"
position
to
shut
off
the electric fuel pump and accessories.
If
not in
"OFF"
position,
it
may drain the batteries.
6. Open battery master switch
ONLY
AFTER ENGINE HAS COME
TO
A COMPLETE STOP!
This will prevent alternator and regulator damage.
7.
00
NOT
USE
THE
DECOMPRESSION LEVER
TO
STOP THE ENGINE! This practice could
seriously
damage the exhaust valves.
8. You may want
to
close
the
fuel and sea water valves after stopping the engine.
If
so, BE SURE
TO
RE-OPEN
THEM
BEFORE RESTARTING. FAILURE
TO
00
SO COULD CAUSE ENGINE
TO OVERHEAT
AND DAMAGE
TO
THE PUMP IMPELLER, OR FUEL LINES TO BECOME AIR
LOCKED. THIS SITUATION WOULD
THEN REQUIRE BLEEDING
OF
THE FUEL SYSTEM
BEFORE RESTARTING ANDIOR REPLACING
THE PUMP IMPELLER.
