Step 3: This inspection requires the operation of the engine with the engine compartment open and should be per-
formed by your MasterCraft dealer. Your dealer will start the engine with the engine compartment open and look for signs
of leakage. Because the fuel system is under pressure, any leaks should be quickly noticeable. If any leaks are observed the
engine must be 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 discon-
nected 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 com-
partment. DO NOT IGNORE NOR OVERLOOK THIS INSPECTION AND REPAIR AS NECESSARY!

NSPECT THE EXHAUST SYSTEM FOR LEAKS
This inspection requires the operation of the engine with the engine
compartment open, thereby creating a potentially dangerous situation.
Therefore, this inspection should be performed by your authorized
MasterCraft dealer. Whenever this inspection is performed, utmost 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 impor-
tant to consider, 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 2006 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 the voltage level reaches a set level of
