Multi-Function Gauge
(ProStar 190, ProStar 197, X-7, X-1 models only)
This gauge provides several func- tions of interest and support to the boater. As a tachometer, it indicates the engine speed in crankshaft revo- lutions per minute (RPM).
As you toggle to the hourmeter, it registers the accumulated engine operating time. Use the hourmeter
to keep accurate logs for scheduled maintenance. (See also the Maintenance Section and Service Log.) Replacing the computer (known as the MMDC) will erase the registered hours. The hourmeter counts hours only when the engine is above 300 rpm.
The option exists to change the display to metric from the hours screen. This is done by holding down the gauge selection display button for three (3) seconds. When prompted, select English
or metric display. Wait an additional three (3) seconds and the display will return to normal operation.
Toggle to the air temperature gauge (optional) to get an ap- proximate reading of the ambient air temperature above the water’s surface.
Toggle to the clock for the convenience of determining the time. It can be adjusted by depressing the gauge selection display button when the clock is displayed. After three (3) seconds the colon will stop flashing. The hours are adjusted by pressing the button down, while minutes are adjusted by pressing up. After three (3) additional seconds the clock will return to normal operation.
Alarms of the Multi-Function Gauge
In addition to the displays noted above, the multi-function gauge also displays several alarms. The following messages will be displayed if an alarm occurs:
VOLT = Voltage falls below 11.5 volts. This message indicates that the battery has discharged to an extent that may jeopardize engine cranking and starting if action is not taken. Start the engine to at least idle, and allow the battery to re-charge.
OIL = Oil pressure is below 4 p.s.i. when the RPM is below 1000 RPM or the oil pressure is below 10 p.s.i. and above 1000 RPM. This message will occur only when the engine is running. Stop the engine and check the oil level as soon as this can be safely done.
TEMP = High engine temperature alarm. This message will oc- cur only when the engine is running. If the engine does not automatically reduce speed to the “limp home” level, manually reduce speed and return to the dock as soon as this can be safely done. It may be necessary to shut down the engine and seek a tow to the dock.
TRAN = Transmission alarm.This message will occur only when the engine is running. Stop the engine and check the transmission oil level as soon as this can be safely done.
While air temperature readings are an optional addition to the gauge, the lake temperature reading is standard on the gauge. This comes from the paddle wheel located under the boat. If the sensor becomes open or shorts out in the line to the battery, it will read 32 degrees F. If the sensor is shorted to the ground wire, it will read 150 degrees F. The SELF TEST feature of the multi-function gauge is located on the lake temperature gauge. With the lake temperature displayed, hold down the gauge selec- tion display button for three (3) seconds or until the self test has started. During the self-test, all the segments on the display will light up. Also during the self test, the gauges will re-set, go to mid-scale and then to full-scale. After two (2) sweeps the system will return to normal.
Navigation/Anchor Lights Switch
(All Models)
A three-position switch serves to activate exterior lighting. Turning the switch in the up position will activate bow and stern lights, the middle position is OFF, and the down position is for stern-only lighting.
Other Alarms
(All Models)
Sensors check the oil pressure, engine and transmission tem- peratures. If the system detects readings outside the acceptable range, the system shuts off the stereo and sounds the alarm for a period of one (1) minute. This signals the need to return to shore as soon as possible and seek assistance from your autho- rized MasterCraft dealer’s service department to diagnose and, if necessary, repair the problem.
Refrigerator Switch
(MariStar 280, X-80, CSX 265, X-65)
This switch will run the refrigerator when turned ON. The refrigerator runs off the boat’s electrical and battery system. There- fore, care should be given to ensure that the battery is not drained to such an extent that the voltmeter alarm sounds.
Seat Heat Switches
(Optional All Models for Driver’s Seat; Certain Models for Observer’s Seat)
A two-position switch allows heat to be turned ON for the driver’s seat. In some models, an optional observer seat heat switch is available and will be found on the deck below the observer seat cushion.
