ENGINE INSTRUMENTATION
1. THE IMPORTANCE OF ENGINE INSTRUMENTATION
To avoid the possibility of mechanical damage to your Engine basic instrumentation for each
Engine is provided on your Intrepid. Unless specified at the time an Intrepid was ordered from the
factory, your boat will be fitted with instrumentation provided by the Engine Manufacturer.
The operator of this boat should become accustomed to checking the instrumentation frequently
when running and particularly when first starting the Engine.
Engine instrumentation gives indications as to what is happening to the engines while they are
being operated. It is important that you become familiar with the appropriate reading for each
instrument. This information is provided by the Engine Manufacturer and is located in your
Owner’s Packet.
Power is provided to an engine’s instrumentation by that engine’s electrical system. The engine’s
Ignition Switch must be on for the instruments to operate.
2. BASIC ENGINE INSTRUMENTATION
TACHOMETER
This instrument provides a reading of Revolutions Per Minute (RPM) of the engine. There is no
set correlation of RPM’s to the speed of the boat. Speeds at various RPM’s should be determined
by using a Speedometer or an electronic device.
VOLTMETER
This instrument monitor’s the amount of charge available in the engine battery. A low voltage
reading when the engine is not running indicates that the battery is not at full charge. A voltage
indication of 13 to 15 volts when the engine is running indicates that the battery is charging.
FUEL GAUGE
The electric fuel gauge indicates the amount of fuel remaining in the fuel tank in terms of
percentage of tank capacity.
The fuel gauge provides a convenient but approximate indication of remaining fuel. Safe
operation of this boat requires filling the fuel tank after each use and becoming familiar with fuel
usage under various conditions.
NOTE
If your Intrepid is equipped with an auxiliary Fuel Tank but has only one Fuel Gauge, your boat
has been fitted with a Main Tank / Auxiliary Tank Selector switch located on your console.
Selecting MAIN will provide a fuel level reading for the Main Tank and an AUX selection will
provide a fuel level reading on the Auxiliary Tank.
NOTE
The fuel senders mounted into the tanks are located under access plates in the cockpit deck.
These senders control the electric gauge on the helm and incorporate a mechanical indication of
Fuel Level on top of each sender.
TRIM GAUGE
The trim gauge provides an indication of the amount an engine is trimmed up or down. Monitoring
this gauge will provide you with the ability to set the amount of engine trim for optimum
performance.
