ENGINE
BREAK-IN
PROCEDURE
DESCRIPTION
Although
your
engine
has
experienced
a
minimum
of
one
hour of test
operations
at
the
factory
to
make
sure
accurate
assembly
procedures
were
followed
and
that
the
engine
oper-
ated
properly,
a break-in
time
is
required.
The
service
life of
your engine
is
dependent
upon
how
the
engine
is
operated
and
serviced
during
its initial 50
hours
of
use.
Breaking-in a
new
engine
basically
involves
seating
the
pis-
ton
rings
to the cylinder
walls.
Excessive
oil
consumption
and
smoky
operation
indicate that the
cylinder
walls
are
scored,
which is caused by
overloading
the engine during the
break-in period.
Your
new
engine
requires
approximately
50
hours
of initial
conditioning operation
to
break
in
each
moving
part
in order
to
maximize
the
performance
and
service
life of
the
engine.
Perform
this
conditioning
carefully,
keeping
in
mind
the
fol-
lowing:
1.
Start
the
engine
according
to
the
STARTING
PROCE-
DURE
section.
Run
the
engine
at fast idle
while
checking
that
all
systems
(raw
water
pump,
oil
pressure,
battery
charging)
are
functioning.
2.
Allow
the
engine
to
warm
up
(preferably
by
running at
fast idle)
until
the
water
temperature
gauge
moves
into
the
130
- 140'P
(55
- 60'C)
range.
3.
While
using
the
vessel,
run
the
engine
at
various
engine
speeds
for
the
first
25
hours.
Avoid
prolonged
periods
of
idling.
4.
Avoid
rapid
acceleration,
especially
with
a cold
engine.
5.
Use
caution
not
to
overload
the
engine.
The
presence
of a
grey
or
black
exhaust
and
the
inability
of the
engine
to
reach
its
full
rated
speed
are
signs
of
an
overload.
,6.
During
the
next
25
hours,
the
engine
may
be
operated
at
varying
engine
speeds,
with
short
runs
at
full
rated
rpm.
Avoid
prolonged
idling
during
this
break-in
period.
CHECKLIST
o Monitor
the
control
panel
gauges.
o .
Check
for
leaks
of
fuel
and
engine
oil.
o
Check
for
abnormal
noise
such
as
knocking,
friction,
vibration
and
blow-back
sounds.
o
Confirm
exhaust
smoke:
When
the
engine
is
cold
-
white
smoke.
When
the
engine
is
warm
-
almost
smokeless.
When
the
engine
is
overloaded
-
some
black
smoke
and
soot.
