255 Owner’s Manual
3-21
Operating Information
3. TACHOMETER -
Registers engine speed in
revolutions per minute (rpm). Use this gauge to
keep the engine within the proper operating range.
Refer to the engine operator’s manual for correct
specifications.
4. COMPASS (Optional) -
The compass has not
been compensated (adjusted). The compensating
should be performed by a qualified compass
adjuster. After the compass has been adjusted, do
not allow any iron or steel objects to be placed near
the compass - even temporarily. Refer to the
operator’s manuals supplied in your owner’s packet.
5. FUEL (Fuel Level Gauge) -
Measures the
approximate level of fuel in a fuel tank.
The ignition switch must be in the RUN position to
activate the gauge. Since the accuracy of your
gauge varies with the attitude of your Cobalt boat,
and the fuel pick-up tube cannot withdraw all fuel
out of the tank, please observe the One Third Rule.
Use one third of your fuel to go out, one third to
come back and one third as a reserve.
6. SPEEDOMETER -
Registers forward speed in
miles per hour. Since the speedometer input is
received from water pressure, accuracy is only
approximate.
7. VOLTS (Voltmeter) -
Indicates the condition of
the engine’s cranking battery in volts DC. With the
ignition switch on and the engine not running, a
reading between 11.5 and 12.5 volts indicates a
fully charged battery. With the engine running at
idle, the gauge should read between 10 and 12
volts. With the engine running at cruising speeds
and above, it should show 12 to 14 volts. See your
authorized Cobalt dealer and have the charging
system checked if the voltmeter reads below these
normal ranges.
8. TRIM (Trim Gauge) -
This gauge indicates the
angle position of the engine’s outdrive relative to
the position of the bow, up or down when boat is on
plane. Use this gauge in combination with the trim
switches located in the throttle control.
9. BILGE BLOWER -
This switch activates the
engine compartment ventilation blower to remove
explosive fumes from the area. The blower must be
operated for a minimum of four minutes each time
before starting the engine or generator. In addition,
the blower should be operated continuously when
at idle or running at slow speeds.
10. BILGE PUMP -
This switch manually controls
the bilge pump.
11. NAV. LIGHTS -
NAV/ANC “Lights” - This three
position switch activates the navigational (running)
lights and the anchor light. After installing the light,
press the switch toward the “NAV.” Press the switch
toward the “ANC” and the anchoring/mooring light
(360° white) will illuminate.
Navigational Lights - You must use your
navigational lights (running lights) when operating
your Cobalt boat between sunset and sunrise, and
when day time visibility is limited. Also, check with
the local authorities before operating your boat, for
other requirements concerning the use of
navigational lights.
The navigational lights are identified by a red light
on the port side of the vessel, and a green light on
the starboard side.
Anchor/Mooring Light - All boats at anchor or
moored must display a proper white anchor light.
The anchor light (all around light) is the white light
located aft of the cockpit. The anchor light must be
visible from 360° and will remain on when operating
the navigational lights.
12. INTERIOR LIGHTS -
This switch provides
illumination within the cockpit.
13. DOCKING LIGHTS (Optional) -
This switch
operates the docking lights.
NOTICE: Operate the boat
between sunset and sunrise
using your navigational lights.
Navigational lights are legally
required to indicate direction
and right-of-way at night.
