INTRODUCTION
The authors
estimate
75% of engine re-
pair work can be directly
or indirectly
at-
tributed
to
lack
of
proper
care
for
the
engine.
This is
especially
true
of
care
during
the
off-season
period.
There
is no
way on this
green
earth
for a mechanical
engine,
particularily
an outboard
motor,
to
be left sitting
idle for an extended
period of
time,
say for six months, and then be ready
for instant satisfactory
service.
Imagine,
if you will, leaving
your auto-
mobile for six months, and then expecting
to
turn
the
key, have
it roar
to life,
and be
able to drive off in the same
manner
as a
daily occurrence.
BOW -

Common
terminology
used throughout
the world for
ref erence
designation
on
boats.
These are the
terms
used in this book.
It is critical
for an outboard engine to be
run at least once a month, preferably,
in the
water.
At the same time,
the shift mecha-
nism
should
be operated
through
the
full
range several
times and the steering
operat-
ed from hard-over
to hard-over.
Only through a regular maintenance
pro-
gram can the owner expect
to receive
long
life
and satisfactory
performance
at mini-
mum cost.
Many times,
if an outboard
is not per-
forming
properly,
the owner will "nurse"
it
through
the season
with good intentions
of
working
on the
unit
once
it
is no longer
being
used.
As
with
many
New
Year's
resolutions,
the
good
intentions
are
not
completed
and
the
outboard
may
lie
for
many months
before
the
work is begun or
the
unit
is taken
to
the
marine
shop for
repair.
Imagine,
if you will,
the
cause
of the
problem being a blown head gasket.
And let
us assume
water
has found its
way into
a
cy linder.
This
water,
allowed
to
remain
over a long period of time, will do consider-
ably more damage
than it would have if the
unit had been
disassembled
and the
repair
work
performed
immediately.
THERE-
FORE,
if
an
outboard
is
not
functioning
properly,
DO NOT
stow it away with promis-
es to get at it when you get time,
because
the
work and expense
will only get worse,
the
longer
corrective
action
is postponed.
In the example
of the blown head gasket,
a
relatively
simple and inexpensive
repair
job
could very well develop into major overhaul
and rebuild work.
Outboards On Sail Boats
Owners of sail boats pride themselves
in
their
ability
to
use
the
wind to
clear
a
harbor
or
for
movement
from
Port A to
Port B, or maybe
just
for a day sail
on a
