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.
Perfonn
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 wann
up
(preferably
by
running at
fast
idle)
until
the water temperature
gauge
moves into
the
130
- 140°F
(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.
CHECK
LIST
D
Monitor
the
control
panel
gauges.
D Check
for
leaks of
fuel
and
engine
oil.
D Check
for
abnormal
noise
such
as
knocking,
friction,
vibration
and
blow-back
sounds.
D Confinn 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
