VOLTMETER
The voltmeter (optional) indicates the battery charge with the engines o and the charging system output with the engine running. A reading of
12 or 13 volts with the engines o is normal, indicating a fully-charged battery. Readings below 11 indicate a weak battery which may not start
an engine. A reading of 13 to 15 volts when the engine is running is normal. Readings over 15 volts may indicate regulator problems. Low or
uctuating readings may indicate loose connections or trouble in the regulator and alternator circuit.
ENGINE LUBRICATION
4-STROKE ENGINES
Your Yamaha 4-stroke engine is equipped with an engine oil system similar to an automobile. The owner should check the oil condition and level
after the rst few hours of operation, and follow a routine oil change schedule as recommended in your engine manual.
WARNING SYSTEMS
WATER TEMPERATURE AND OIL LEVEL
Outboard engines have several warning systems. The buzzer for these systems is located under the dash. Some models also have indicator lights
in addition to the audible alarm. The purpose of the buzzer is to alert the driver to potentially damaging engine operating conditions. Consult your
engine owner’s manual for exact location and function of these systems. Yamaha engine warning systems also incorporate an RPM reduction mode
that when working properly eectively controls the engine RPM. The maximum RPM achievable when a Yamaha warning system is activated is
2,500 RPM. Consult your authorized dealer if your engine is not achieving proper operating RPM.
