INSTRUMENTS
The following is a brief explanation of instrumentation typically found on some boats. The owner/operator should
be familiar with all instruments and their functions on the boat. Because of the large variety of instrumentation
and manufacturers, you should have your boat dealer explain the particular gauges and normal readings that
will appear on your style gauges.
1 Speedometer: Indicates boat speed.
2 Tachometer: Indicates engine rpm.
3 Oil Pressure Gauge: Indicates engine oil pressure.
4 Battery Meter: Indicates battery voltage.
5 Coolant Temperature Gauge: Indicates engine operating temperature.
6 Fuel Gauge: Indicates quantity of fuel in tank.
7 Power Trim Gauge: Indicates drive unit angle (trim UP/OUT and DOWN/IN).
8 Hour Meter: Records engine running time.
