UCAUTION
II
Do not nse a scoop-type thru-hull fitting as a means
of
supplying sea water to the generator.
Water pressure against this type fitting, while the vessel is under way, can push sea water past
the sea water pump's impeller into the generator's exhaust system, filling it and the engine as
well. Flush-type, clear, thru-hull fittings are recommended and should be located on the hull so
as to
be
below the waterline during all angles
of
boat operation.
The use
of
common-type street elbows is not recommended for plumbing the sea water circuit.
These generally have very restrictive inside diameters. Machined fittings are preferred.
Automatic Shutdown
High Exhaust Temperature Shutdown Switch (normally closed)
An exhaust temperature switch is located on the exhaust elbow. This switch will open and shut the fuel
solenoid
OFF (which turns OFF the engine) should the switch's sensor indicate an excessive exhaust
temperature (an inadequate supply
of
sea water coolant causes high exhaust temperatures). This switch
opens at
260
0
- 270
0
F (127 - 132
0
C). This switch resets at
195
0
F (107
0
C).
Low
Oil Pressure Shutdown Switch (normally open)
A low oil pressure shutdown switch is located off the engine's oil gallery. This switch's sensor monitors
the engine's oil pressure. Should the engine's oil pressure fall
to
10-15 psi, the switch will open shutting
OFF the fuel solenoid (which turns OFF the engine).
I WARNING I
Although diesel engine exhaust gases are not as toxic as exhaust fumes from gasoline engines,
carbon monoxide is present in diesel exhaust fumes. Carbon monoxide is a dangerous gas that
can cause unconsciousness and
is
potentially lethal. Some
of
the symptoms or signs
of
carbon
monoxide inhalation or poisoning are listed below.
• Dizziness
• Vomiting
• Intense headache • Muscular twitching
• Weakness and sleepiness • Throbbing in temples
If
you experience any
of
the above symptoms, get out into fresh air immediately.
