These gauges function on your boat the same way
they do on your car or truck. You must continually
check these gauges visually to make certain there
are no engine system problems even if your boat
engine has an alarm system.

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.
The hourmeters measure cumulative hours of
operating time. The hourmeter should be used to
keep a careful log of engine maintenance as well
as performance data and fuel consumption. Do not
leave ignition key ON with the engines off, as this
will increase the engine hours on the hourmeter.

OMPASS
Your compass (See Figure 2.7.2), properly
corrected, will indicate magnetic North (not true
North). A compass must be adjusted by a qualified
person. The reason for this is that nearby
instruments or objects containing magnets or
current-carrying electrical wires will influence the
compass reading. This is especially true if you add
electronic devices to the helm station.
After your compass has been professionally
adjusted. You will be given a deviation card or chart
indicating the correction to be applied when laying
out a compass course or making navigational
calculations.
Keep this correction card or chart
at the helm.
NOTE:
The compass adjustment is only good for
the equipment arrangement that existed at the time
of the adjustment. If you place different equipment
or remove equipment from the vicinity of the
compass, you cannot rely on the compass reading.
The compass must be readjusted by a qualified
person after equipment is added or removed from
the vicinity of the compass.
NOTE:
The compass roses shown on navigational
charts have both true North and magnetic North
directions superimposed. Make certain you plot
course compass directions from the magnetic North
compass rose.
When not in use, the compass should be protected
from excessive and prolonged sunlight. If your
compass becomes sluggish or erratic, it should be
serviced by an authorized repair station.
To keep the plexiglass dome free from scratches,
remove salt deposits and dust with a damp cloth.
An occasional treatment with paste wax will help
preserve the dome surface.
