1.6 Engine Instrumentation
The helm station is equipped with a set of engine
instruments and alarms. These instruments allow the
pilot to monitor the engines’ operational conditions.
Close observation of these instruments allows the pilot
to operate the engines at the most efficient level and
could save them from serious costly damage. The
instrumentation is unique to the type of outboard 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 or 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 SEIZURE. IF AN UNUSUALLY HIGH TEMPERATURE READING
OCCURS, SHUT THE ENGINE OFF IMMEDIATELY. THEN INVESTIGATE
AND CORRECT THE PROBLEM.
Speedometer
The speedometer indicates the speed of the boat in miles per hour. Most speedometers measure the
water pressure against a small hole in a pickup tube located in the engine lower unit or mounted
on the bottom of the transom.
Fuel Gauge
The fuel gauge indicates the amount of fuel in the fuel tanks. The fuel gauge switch, located on
the helm, is used to switch the gauge reading to the port or starboard fuel tank.
