Westerbeke ATOMIC 4 User Manual

discharged harmlessly over the side.
Connection from the tank to the
engine should be made with copper
tubing of a size recommended by the
engine manufacturer. A short sect ion
of flexible line should be placed
in the line at the point of attach-
ment to the fuel pump to prevent
leaks occurring due to fatigue of
the metal tubing.
9. ELECTRICAL SYSTEM
The importance of adequate and safe
wir ing aboard a boat cannot be over-
emphasized. All connections must be
clean, tight, and free from oil.
'There solder connections are neces-
sary, the connection should be made
mechanically secure before soldering
Use only rosin flux when soldering
to prevent corrosion. All wiring
should be kept as short as possible
to mInImIze voltage drop in the
circuits.
A battery box should be built as
close to the engine as possible,
securely fastened to the boat and
of a size to prevent shifting of
the battery. Any cover on the box
should be readily removable for
periodic checking of water level
in the battery (See Fig. 10).
All wiring should be run in such
a fashion as to prevent mechanical
injury. Wires for all circuits
should be of a large enough size to
minimize voltage drop in the cir-
cuit and of sufficient current car-
rying capacity to prevent overheat-
ing. (See Table J)
10. FINISHING THE JOB
The instrument panel may be in-
stalled at any convenient location
at the control station. Oil pres-
sure and water temperature gauges
should be connected in accordance
~ith the instructions that come
with the unit.
Gear shifting can be accomplished
by using the shifting lever supplied
with most engines or one of several
types of controls available. These
controls may be operated from a
remote lever, either mechanically
through a system of rods or hydrau-
lically through piping.
With the engine installed, the pro-
peller is then fastened to the
shaft, care being taken to maintain
proper clearances from the bottom
of the boat and the rudder.
After the engine is installed and
all connections completed, the en-
gine should be enclosed in an en-
gine box. In designing this box,
keep in mind the possibility that
it may be necessary to make adjust-
ments or repairs in the future. A
box with removable top and sides
is desirable.
It must also be kept in mind that
an internal combustion engine uses
roughly 14 parts of air to one part
of gasoline when operating. There-
fore, sufficient ventilation must
be provided to allow it to operate
at full efficiency. This will vary
with the size of the engine; the
higher the horsepower the greater
must be the ventilating area. Five
square inches of ventilating area
is sufficient for engines up to 25
H.P. and 15 square inches for' en-
gines up to 150 H.P.
After complet ion of the installat ion
and with the boat in the water, the
alignment of the engine to the
propeller shaft should be checked
once more. The engine may then be
started and all connections checked
for signs of leaks. Oil pressure
and water temperature gauges should
be closely watched for signs of im-
proper operation. After making sure
that everything is operating properl
the boat should be taken on a short
run at slow speed. Final checking
and adjusting is done on this trip
and the boat is now ready for opera-
tion.
