the engine compartment. DO NOT IGNORE OR OVERLOOK THIS INSPECTION AND REPAIR AS
NECESSARY!
Inspect the Exhaust System for Leaks
is 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 starting switch is disconnected.
Be certain that the throttle/shift control lever is in neutral. e 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 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 tran-
som for any obvious damage to exhaust lines or the muffler.
Step 3: If leakage is apparent, tighten the hose clamps, being careful to avoid crimping the hose. If the leak-
age 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. is is important!
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. DO NOT IGNORE OR OVERLOOK THIS INSPEC-
TION! 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, but pay particular 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. e 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 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.
Current models are equipped 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 difficulties re-
starting the boat. To avoid this situation, when the voltage level falls to 11.5 volts, the system will shut
off the stereo system and sound an alarm for a period of two (2) minutes to allow the operator 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 attempting to start the engine. (Some Master-
Craft 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.
