The Engine Operator's Manual will tell you if your
engine is equipped with an audible alarm and how
to use it.
The alarm indicates a problem with engine water
temperature, oil pressure and/or stern drive oil
level.

The tachometer (see Figure 2.6.2) 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 hour meter measures cumulative hours of
operating time on the engine. Use the hour meter
to keep a careful log of when to maintain the engine
as well as to estimate fuel consumption. Do not
leave ignition key in the "ON" position with engine
off, because the hour meter will continue to run,
even though the engine is not operating.
Always check oil pressure and water gauges
while moving, even if your engine has an
alarm.
Shut down engine immediately if gauges are
not in normal ranges, or alarm sounds.
Do not restart engine until problems are
corrected.

Figure 2.6.1 shows the ignition shutdown switch, if
your boat has one. The purpose of the switch is to
shut down the engine if the operator unintentionally
leaves the helm station. Situations in which this
could occur are rough water, bad weather and other
adverse boating conditions. In these situations, the
safety of the boat and its passengers is enhanced
by using the ignition shutdown switch, since the boat
will stop when the operator can no longer control
the boat.
However, unexpected engine shutdown may result
in unintentional harm. For example, a passenger
may lose balance and fall, or control could be lost
during docking. No specic guidelines can be given
for switch use. The ultimate decision of when to use
an ignition shutdown switch rests with the operator
or owner.
When the switch is used, the operator must securely
clip the lanyard to their belt or clothing so that if the
operator falls overboard or into the boat, the switch
is activated and the engine shuts down.

If you raise the stern drive up too far while on plane, you
could cause a loss of speed and power due to a condition
called propeller "ventilation." If this happens, there will
be a sudden increase in engine RPM and loss of speed.
Do not let this condition exist. Immediately reduce your
engine RPM and trim the outdrive DOWN slightly until
engine slows down and you regain forward speed.
The trim gauge indicates the position of the stern drive
relative to the transom.
REFER TO YOUR ENGINE OPERATOR'S MANUAL
FOR PROPER TRIM GAUGE SETTING.
