DO NOT IGNORE OR OVERLOOK THIS INSPECTION! REPAIR AS
NECESSARY!
BEFORE EACH USE
After Starting the Engine
Check That The Battery Is Fully Charged
As the boat is started, check all gauges (analog dash mounted for X
and XT Series, digital display for XStar and NXT Series), but pay par-
ticular attention to the voltage. (On all models, press the Gauge soft
key on the left side of the touch screen to access this information.)
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 voltage reading is the best indication of the status of your bat-
tery, however it is not fool-proof. While the reading may indicate that
the battery is producing current, if during a previous operation you
had reason to suspect a problem with your battery, check with an
authorized MasterCraft dealer’s service department.
Gasoline is highly flammable and its vapors may ignite, resulting in
fire or explosion. Be sure to keep all sparks and flames away from
the area while inspecting the boat’s fuel system.
Step 2
Open the engine compartment and visually check as much of the
fuel system from the tank to the engine as you can see. On some
models this is will be a limited area. If the odor of gasoline is strong
or if you see visual evidence of fuel outside the system, cease all
operations and take the boat immediately to an authorized Mas-
terCraft dealer’s service department to determine the source of
the leak. The leak must be repaired before the engine is restarted.
Because the lines on late model MasterCraft boats are pressurized,
they can be disconnected and/or removed ONLY by using special-
ized tools.
The engine box serves as a machinery guard. The engine must
be OFF whenever the box is open. Clothing for body parts can get
caught in moving parts, causing death or serious injury. Keep away
from moving parts!
Fuel leakage can lead to a build-up of potentially explosive fumes
within the engine compartment. DO NOT IGNORE OR OVERLOOK
THIS INSPECTION AND REPAIR AS NECESSARY!
NOTE ANY EXHAUST ODORS
This function should be performed prior to starting the engine; and
then again after about three (3)-to-five (5) minutes to determine
whether any leaks are apparent.
Step 1
First ensure that the engine is OFF and that the engine safety start-
ing switch is disconnected. Be certain that the throttle/shift control
lever is in neutral. The engine must be cool.
Step 2
Open the engine compartment and note whether there is any un-
usual odor. In many instances, exhaust will have little or no odor, but
in the event of a potentially significant exhaust leakage, it may be
possible to smell a “rotten-egg” odor that signifies a probable issue
that must be addressed.
Step 3
If leakage is apparent, tighten the hose clamps, being careful to
avoid crimping the hose. If the leakage is significant, 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.
Exhaust fumes can cause illness or impairment, including carbon
monoxide poisoning. Equally important to consider, leakage can
lead to a build-up of potentially explosive fumes within the engine
compartment.
any kinks and wear on the outer jacket. Any sign of cable damage is
cause for replacement. See your authorized MasterCraft dealer’s
service department if you notice any cable damage.
INSPECT THE FUEL SYSTEM
FOR LEAKS
This function should be performed prior to starting the engine; and
then again after about three (3)-to-five (5) minutes to determine
whether any leaks are apparent.
Step 1
Ensure the engine is OFF, the engine safety starting switch is dis-
connected and the throttle/shift control lever is in neutral.
