Tachometer
DO NOT rely on the speedometer when trying
to achieve a "NO WAKE" condition in a harbor
or other enclosed water way. ALWAYS reduce
throttle! Speed ometers are not effective at mea-
suring low opera tional speeds. You are
your boat.
B. Tachometer - Analog & Digital Readings
Tachometer indicates the revolutions per minute
(RPM) of the engine. Multiply by 1000 to obtain the
actual revolutions. This speed is not the boat speed.
The tachometer may not register zero with the ignition
key in the OFF position. See Figures B7 & B9.
Never exceed the maximum recommend ed
operat ing RPM of your engine. Main taining
maximum, or close to maximum RPM for
extended periods can reduce the life of the
engine.
Some engines are equipped with devices that limit
engine RPM in accordance with the oil pres sure, or
engine temperature. Refer to the engine manual
included in the owner's packet for additional informa-
tion.

The hour meter provides a numeric record of elapsed
engine operating time. It displays the time in hours of
the boat's usage. See Figure B9. This information is

intervals, ship's log data, cruise information, etc.
