ACHOMETER
The tachometer indicates the revolutions per minute
(RPM) of the engine. (It does not indicate the speed
of the boat.) Your Engine Operator’s Manual
indicates the maximum full throttle RPM at which
your engine should operate. This must not be
exceeded or serious engine damage will occur. The
tachometer should also be used to determine the
most comfortable and economical cruising RPM.
