5.6.1 Tachometer
The tachometer displays the speed of the engine in revolutions per minute
(RPMs). This is not the boat’s speed over the water or the speed of propeller
rotation. The tachometer may not register zero RPM when its engine’s
ignition key is turned off; this is normal.
The engine manufacturer has established a maximum RPM rating for your
engines, as listed in the engine OEM information. Do not exceed the
maximum RPM. Doing so could damage the engines.
5.6.2 Temperature Gauge
The temperature gauge displays the temperature of the coolant in the
engine’s cooling system. Every engine is designed to operate within a spe-
cific temperature range. Refer to the engine OEM information for the
normal operating temperature range of your engines. A sudden increase in
the temperature gauge reading could indicate that the cooling system has
become blocked; a cooling system intake hose has failed; or the coolant
system’s water pump has malfunctioned.
Each engine is equipped with a temperature alarm. The alarm sounds when
the temperature of the engine’s coolant increases to a predetermined point.
If the alarm sounds, immediately shut off the affected engine.
Even with high temperature alarms installed, it is important that you
visually monitor both temperature gauges while running the engines. If a
temperature gauge indicates excessive engine temperature, immediately
shut off the affected engine.

A cold engine has a tendency to stall when first put into gear. Let your engines
warm up a few minutes before departing your dock or anchorage.
The engine manufacturer has established a maximum coolant tempera-
ture rating for your engines, as listed in the engine OEM information. Do
not exceed the maximum coolant temperature. Doing so could damage
the engines.
