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. Likewise, your
engines have a minimum wide open throttle RPM requirement. If your
engine will not reach this minimum RPM contact your Carver dealer.
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 specific
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.
The engine manufacturer has established a maximum coolant temperature rating
for your engines, as listed in the engine OEM information. Do not exceed the
maximum coolant temperature; doing so could damage the engines.
Oil Pressure Gauge
The oil pressure gauge displays the pressure within the engine’s lubrication
system. The oil pressure reading changes as engine speed changes. However, a
noticeable decrease (either sudden or gradual) in an engine’s oil pressure while
the boat is maintaining a constant speed may indicate an oil pump failure, a leak
in the lubrication system or excessive engine wear.
Each engine is equipped with a pressure alarm. The alarm sounds when the
pressure in the lubrication system decreases to a predetermined point. The alarm
also sounds when the engine is started or when the ignition switch is “ON”
and the engine is not running. In these situations, the engine does not yet have
adequate oil pressure; the alarm is silenced as soon as the oil pressure increases
to within the normal operating range. Refer to the engine OEM information for
the normal operating range.
A Tip From Carver!
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.
