2870 WALKAROUND
1.6 Engine Instrumentation
The helm station is equipped with a set of
engine instruments and/or alarms. These instru-
ments 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 out-
board 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.
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.
Temperature Gauge
The temperature gauge shows the temperature of the engine cooling system. 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 ENGINE
OFF IMMEDIATELY. THEN INVESTIGATE AND CORRECT THE PROBLEM.
Water Pressure Gauge
The water pressure gauge monitors the water pressure in the engine cooling system. Refer to the
engine manufacturer owner’s manual for more information on the cooling system water pressure
requirements for your engines.
