immediately shut down. The leak must be repaired before the engine is restarted. See your MasterCraft dealer for parts and
service. Because the lines on late model MasterCraft boats are pressurized, they can be disconnected and/or removed ONLY by
using specialized tools that are not available to the public.
This is important! Fuel leakage can lead to a build-up of potentially explosive fumes within the engine compart-
ment. DO NOT IGNORE NOR OVERLOOK THIS INSPECTION AND REPAIR AS NECESSARY!
INSPECT
THE
EXHAUST
SYSTEM
FOR
LEAKS
This inspection requires the operation of the engine with the engine
compartment open, thereby creating a potentially dangerous situa-
tion. Therefore, this inspection should be performed by your autho-
rized MasterCraft dealer. Whenever this inspection is performed, ut-
most care must be exercised to avoid personal injury or death. Your
MasterCraft dealer will perform the following steps in conducting the
inspection:
Step 1: Ensure that the engine is OFF and that the engine safety starting
switch is disconnected. Be certain that the throttle/shift control lever is
in neutral. The engine must be cool.
The engine box serves as a machinery guard. The engine must be
OFF whenever the box is open. Clothing or body parts can get
caught in moving parts, causing serious injury or death.
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 muffler.
Step 3: This inspection requires the operation of the engine with the engine compartment open and should be performed by your
MasterCraft dealer. Your dealer will start the engine with the engine compartment open.
Step 4: The dealer will carefully inspect the hose connections between the exhaust manifolds and the mufflers for leakage.
Step 5: If leakage is apparent, tighten the hose clamps, being careful not to crimp the hose. If the leakage is significant or is
occuring at a location other than the joints (such as a split in a hose), see your MasterCraft dealer for parts and service. This is
important! Exhaust fumes can cause illness or impairment, including carbon monoxide poisoning. Equally important to con-
sider, leakage can lead to a build-up of potentially explosive fumes within the engine compartment. DO NOT IGNORE NOR
OVERLOOK THIS INSPECTION! REPAIR AS NECESSARY!
CHECK
THAT
THE
BATTERY
IS
FULLY
CHARGED
As you start your boat, check all gauges,but pay particular attention to
the voltmeter.
While starting the engine, check that the voltmeter reads between 12.4 and 14.5. An
erratic reading can be a sign of low voltage. The voltmeter is your best indication of the
state of your battery. It is not fool-proof, however. While the reading will indicate that the
battery is producing current, if in a previous operation you had reason to suspect a
problem with your battery, check with your MasterCraft dealer.
The 2004 models are equipped with a low-voltage battery alarm. In the event that
the stereo has been functioning when the boat is not ON and running, the voltage drain
on the battery can result in difficulties re-starting the boat. To avoid this situation, when
