5.6 Engine Gauges
Each helm is equipped with a complete set of gauges on the instrument
panel. The gauges allow you to monitor the operation and condition of
your boat’s propulsion systems while underway. The side of the instru-
ment panel that the gauges are on (port or starboard) determines the
respective engine that the gauges are for. Familiarize yourself with the
gauges before starting the engines for the first time.
Do not start the engines until you have read and understood the engine
OEM information.
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
specific temperature range. Refer to the engine OEM information for the
normal operating range. A sudden increase in the temperature gauge
reading could indicate that the cooling water intake 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 predeter-
mined 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.
