board engines installed on your Pursuit.
Your boat may not be equipped with all of
the following gauges.
Some models may be equipped with
Yamaha Command Link Integrated
Information System®. Refer to the
Yamaha manuals for information on the
operation of this system.
Tachometer
The tachometer displays the speed of the
engine in revolutions per minute (RPM). This
speed is not the boat speed or the speed of
the propeller. The tachometer may not regis-
ter zero with the key in the “OFF” position.
Speedometer
The speedometer indicates the speed of the
boat in miles per hour (MPH). Most speed-
ometers measure the water pressure
against a small hole in a pick-up tube
located in the engine lower unit or from GPS
in a Yamaha® installation.
Temperature Warning
The temperature warning indicates the tem-
perature of the engine. A sudden increase in
the temperature could indicate an obstructed
water inlet or an impeller failure.
Fuel Gauge
The fuel gauge indicates the approximate
fuel level in the fuel tanks. This gauge is a
relative indication of the fuel supply avail-
able; it is not a calibrated instrument.
Voltmeter
The voltmeter displays the voltage for the
battery and the charging system. The nor-
mal voltage for a full charged battery is 12.6
volts with the engine(s) off and 13 to 14.5
volts with the engine(s) running.
Hourmeter
The hourmeter keeps a running total of
engine hours while operating.
Tilt/Trim Gauge
The tilt/trim gauge monitors the position of
the outboard engine. The upper range of the
gauge indicates the tilt, which is used for
shallow water operation, trailering and to
keep the gear case out of the water. The
lower range indicates the trim position. Trim
is used to adjust the hull angle while operat-
ing your boat on plane. Refer to the engine
owner’s manual for more information on the
operation of the outboard power tilt and trim.
NOTICE
DO NOT exceed maximum recom-
mended engine RPM. Exceeding,
maintaining or close to maintaining
maximum RPM can reduce engine life.
NOTICE
Continued operation of an over-
heated engine will cause severe
engine damage. If the engine over-
heats, shut off the engine, investi-
gate the problem and correct it.
