AFTER EACH USE
General Cleaning And Storage
Refer to the Corrosion Prevention and Cleaning the Boat sections
of this Owner’s Manual. After each outing, the boat should receive a
general cleaning and drying prior to being stored. Even if the boat is
kept in a slip, owners/operators should wipe down the interior and
should periodically remove the boat from the water for a general
cleaning.
In instances of boats being left moored in water, it may be neces-
sary to periodically run the bilge pump to clear out water that has
intruded into the bilge compartment. Keep the battery fully charged
in order to be able to provide this function.
Inspections
As noted in the Before Each Use section, some functions there
need to be performed following use of the boat, such as checking
the intake strainer or seacock strainer if evidence has shown that
debris collects during the outing. Wet debris is often easier to
remove.
Crossing cables or jumper cables may result in damage to the
electrical components due to incorrect battery connections. Such
damages may not be covered by your warranty.
Repeat Check For Fuel And/Or Exhaust Leaks
This function should be performed after about three (3)-to-five (5)
minutes of running the engine to determine whether any leaks are
apparent.
After three (3)-to-five (5) minutes of operation, shut down the
engine and ensure that the engine safety starting switch is discon-
nected. Be certain that the throttle/shift control lever is in neutral.
Again, inspect the fuel system as well as possible. Inspect the fuel
pump gasket, fastener gaskets, regulator seal and sender gasket
for leaks. 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 MasterCraft 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 disconnect-
ed and/or removed ONLY by using specialized tools that are not
available to the public.
Reinspect after the fuel tank has been filled full for the first time of
the season.
Note that fuel systems vary by model. The pump-in-tank location on
top of the fuel tank will resemble one of the two photos.
This is important! 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!
Also, recheck that there is no unusual exhaust odors as described
prior to starting the engine.
Current models are equipped with a low-voltage battery alarm. In
the event that the stereo has been functioning when the boat en-
gine is OFF, the voltage drain on the battery may result in difficulties
restarting the boat. To avoid this situation, when the voltage level
falls to 10.5 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 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 bat-
tery from a third party engine will put undue stress on the alternator,
which may cause it to fail.
When charging, batteries generate small amounts of dangerous
hydrogen gas. This gas is highly explosive. 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.
