1.7 Engine Instrumentation
The helm station is equipped with a set of engine instruments and/or alarms. These instruments allow the pilot
to monitor the engine operational conditions. Close observation of these instruments allows the pilot to operate
the engines at the most efficient level and could save the engines from serious costly damage. The
instrumentation is unique to the type of inboard motors installed on your Pursuit. Some or all of the following
gauges may be present.
Tachometer
The tachometer displays the speed of the engine in revolutions per minute (RPM). This speed is not the boat
speed nor necessarily the speed of the propeller. The tachometer may not register zero with the key in the
“OFF” position.
NEVER EXCEED THE MAXIMUM RECOMMENDED OPERATION RPM OF THE ENGINE.
MAINTAINING MAXIMUM, OR CLOSE TO MAXIMUM, RPM FOR EXTENDED PERIODS
CAN REDUCE THE LIFE OF THE ENGINE.
Temperature Warning
The temperature warning indicates the temperature of the engine. A sudden increase in the temperature could
indicate an obstructed water inlet or an impeller failure.
CONTINUED OPERATION OF AN OVERHEATED ENGINE CAN RESULT IN ENGINE SEI-
ZURE. IF AN UNUSUALLY HIGH TEMPERATURE READING OCCURS, SHUT THE EN-
GINE OFF IMMEDIATELY. THEN INVESTIGATE AND CORRECT THE PROBLEM.
Oil Pressure Gauge
The oil pressure gauge monitors the engine lubrication system pressure. The oil pressure indicated when the
engine is new is usually the reference for normal oil pressure for that engine. A drop in oil pressure is a possible
indication of oil pump problems or a leak.
Fuel Gauge
The fuel gauge indicates the amount of fuel in the fuel tank. This gauge is merely a relative indication of the
available fuel supply and not a calibrated instrument.
Voltmeter
The voltmeter displays the voltage for the battery and the charging system. The normal voltage is 11 to 12
volts with the engine off, and 13 to 14.5 volts with the engine running.
Hour Meter
The hour meter keeps a record of the operating time for the engine. The hour meters are located in the helm
instrument panel or near the battery selector switches in the stern.
Synchronizer Gauge (Optional)
The synchronizer gauge indicates whether or not the engines are operating at the same RPM. The throttles
should be set so the needle is centered.
