3.7 Helm and Engine Instrumentation

The helm station is equipped with a set of engine
instruments and/or alarms. These instruments al-
low the operator to monitor the engine operational
conditions. Close observation of these instru-
ments allows the operator to operate the engine at
the most efficient level and could save the engine
from serious costly damage. The instrumentation
is unique to the type of inboard/outboard motor
installed on your Monterey. Some or all of the
following gauges and instruments 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(s). The tachometer may not register
zero with the key in the "OFF" position.
Tachometers in MSX models with Tow Control may
also have a key pad and LCD screen used in se-
lecting the features included with this option. The
features and controls for Tow Control are unique to
the engine installed in the boat. Refer to the Helm
44
Standard Speedometer and Tachometer with Hour Meter
Control Systems chapter and the engine and/or
control systems manuals for more information on
the Tow Control system in your boat.
CAUTION
MAINTAINING MAXIMUM, OR CLOSE TO MAXIMUM RPM FOR
EXTENDED PERIODS CAN REDUCE THE LIFE OF THE ENGINE.
NEVER EXCEED THE MAXIMUM RECOMMENDED OPERATION
RPM 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 indicates the temperature
of the engine cooling system. A sudden increase
in the temperature could signal a blocked cooling
passage or a water pump malfunction
