Automatic
Alarm
System
High Water Temperature Alarm
A high water temperature alarm buzzer has been supplied with the instrument panel.
If the engine's fresh
water coolant reaches
205" F (96"
C),
a water temperature switch on the engine closes causing the alarm
buzzer to emit a continuous signal. Refer to the
"DESCRIPTION OF INSTRUMENT PANELS" section of this
manual for the location
of
the alarm in your engine panel, page
35.
Low
Oil Pressure Alarm
A
low
oil pressure alarm switch
is
located off the engine's oil gallery. This switch monitors the engine's oil
pressure.
Should the engine's oil pressure fall
to
10
-15
psi, the switch will close sounding this same alarm.
In this event, the alarm will emit a pulsating signal. Refer to the "DESCRIPTION OF INSTRUMENT PANELS"
section
of
this manual for the location
of
the alarm in your engine panel, page
35.
Sea Water
Intake
System
Make sure the intake system (sea water cooling system)
is
in proper order. Check that the hull inlet, sea
cock
and strainer are unobstructed. Sea cocks and strainers should be at least one size greater than the
inlet thread
of
the sea water pump. The strainer should be of the type that may be withdrawn for cleaning
while the vessel is at sea and should be mounted below the water
line
to
ensure self-priming. Inspect the
sea water lines
to
make sure there are no collapsed sections, which would restrict water flow. Make sure
there are no air leaks at any
of
the connections.
Fuel
System
The fuel system should be installed in such a manner
as
to
allow the engine-mounted fuel lift pump
to
main-
tain a positive inlet pressure
to
the injection pump under all operating condftions. The minimum size of the
fuel supply
line and fuel return line
is
1/4 inch, inside diameter, and there
shOUld
be a primary fuel filter in-
stalled between the fuel tank and the fuel lift pump. Only one fuel filter
is
installed on the engine, between
the mechanical fuel lift pump and the injection pump; this
Iilter has a replaceable filter element.
The fuel tank's fuel pickup tube should be clear and unobstructed. No screens
or
gauze strainers should be
Incorporated in the fuel pickup tube.
Make sure that the fuel supply and return
lines are securely anchored
to
prevent chafing and that all fittings
are sufficiently tightened to prevent leaking. Also make sure your fuel system has a positive shut-off valve;
know its location and how it operates.
NOTE: DO NOT use spring-loaded check valves in the fuel supply line in lieu
of
mechanical
shut-off valves. This type valve can create fuel starvation problems for the engine's fuel sys-
tem.
Fuel tanks that are located below the engine's fuel system level must have its fuel return at the tank extend-
ing down into the tank
in
the same manner as the pickup tube, otherwise fuel siphoning out of the engine's
fuel system through the return will take place.
