indicator lights that are used while operating the boat.
All instrument gauges, switches, and indicator lights left
of the panel lights switch are used when operating the
port engine. All others are used for the starboard engine.
The LOW FUEL LEVEL and BATTERIES IN
PARALLEL indicator lights are used for both engines.
Panel lights illuminate both port and starboard gauges.
D
INSTRUMENT PANEL--Contains instrument gauges, switches, and
indicator lights that are used during port and starboard engine operation.
E
from 0150 psi. The gauges allow operator to view current pressure range. The
normal range when engine is at idle speed should be 2030 psi. The PSI range
will increase as engine rpm increases, at 1,000 rpm the engine oil pressure
gauge should indicate approximately 50 psi.
F
ENGINE WATER TEMPERATURE GAUGES--Engine water temperature
gauges range between 0250 F. The normal operating range should be 210 F
or below.
G
gauges range from 0400 psi. The minimum oil pressure while cruising should
not be below 30 psi.
H
BATTERIES IN PARALLEL--Illuminates red when emergency link button
is depressed and all four batteries are being used in parallel for boat
operations.
I
LOW FUEL LEVEL--Illuminates red when there are 12 gallons (45 liters) or
less fuel remaining in the fuel tank.
J
LOW OIL LIGHTS--Illuminate red whenever 20 psi or lower engine oil
pressure is detected.
K
AUXILIARY AND STARTING BATTERIES--Battery volt gauges range
from 1834 volts. The gauges allow operator to view voltage for starting and
auxiliary batteries. Refer to the following specifications.
Engine not running; no electrical load
The following readings are most reliable if the batteries
have stood for at least 8 hours without charge or
discharge.
Battery fully charged
25.4 volts or above
Battery half charged
