e engine box serves as a machinery guard. e
engine must be OFF whenever the box is open.
Clothing or body parts can get caught in moving
parts, causing death or serious injury. Keep away
from moving parts.
Step 2: Open the engine compartment and visually
check the exhaust system from the engine to the transom
for any obvious damage to exhaust lines or the mufer.
Step 3: If leakage is apparent, tighten the hose
clamps, being careful to avoid crimping the hose. If the
leak is signicant, or is occurring at a location other
than the joints (such as a split in a hose), see your
authorized MasterCraft dealer’s service department for
parts and service. This is important! Exhaust fumes
can cause illness or impairment, including carbon
monoxide poisoning. Equally important to consid-
er, leakage can lead to a build-up of potentially ex-
plosive fumes within the engine compartment. DO
NOT IGNORE OR OVERLOOK THIS INSPECTION!
REPAIR AS NECESSARY!
Check at the Battery Is Fully Charged
As the boat is started, check all gauges, but pay particu-
lar attention to the voltmeter.
While starting the engine, check that the voltmeter reads
between 12.4 and 14.5 volts. An erratic reading may be
a sign of low voltage. The voltmeter is the best indication
of the state of your battery. However, it is not fool-proof.
While the reading may indicate that the battery is produc-
ing current, if during a previous operation you had reason
to suspect a problem with your battery, check with an au-
thorized MasterCraft deal-
er’s service department.
Current models are e-
quipped with a low-voltage
battery alarm. In the event
that the stereo has been
functioning when the boat
engine is OFF, the voltage
drain on the battery may
result in difculties re-start-
ing the boat. To avoid
2008 MasterCraft Owners Manual Page 15-4
this situation, when the voltage level falls to11.5 volts,
the system will shut off the stereo system and sound an
alarm for a period of two (2) minutes to allow the opera-
tor time to turn the ignition key ON and start the engine.
Doing so will allow the engine’s alternator to recharge
the battery.
Charge dead batteries with a battery charger before at-
tempting to start the engine. (Some MasterCraft models
offer an optional battery charger; but never jump-start the
battery.) Jump-starting from another boat or battery
is dangerous! Charging a dead battery from an engine
will put undue stress on the alternator, which may cause
it to fail.
When charging, batteries generate small amounts
of dangerous hydrogen gas. is gas is highly ex-
plosive. Keep all sparks, flames and smoking well
away from the area. Failure to follow instructions
when charging a battery may cause an electrical
charge or even an explosion of the battery, which
could cause death or serious injury.
Crossing cables or jumper cables may result in
damage to the electrical components due to incor-
rect battery connections. Such damages may not
be covered by your warranty.
