2017 OWNERS MANUAL /

NOTE: The switch knob may be removed when it is in the OFF posi-
tion. This is a security feature to ensure that batteries are OFF. If
the engine will not start because the battery is discharged, follow
recharging instructions described in the Electrical Instructions
section of the Owners Manual.
Bilge pumps will not operate in either the manual or automatic
mode if the batteries are fully discharged. This condition may allow
excessive water into the hull which can damage or sink the boat.
Make frequent checks of battery charge and bilge pump function
when boats are moored and exposed to the elements.
Troubleshooting
Because battery needs can vary substantially depending on a
number of factors including usage, location and the number of elec-
trical components in use on the boat, MasterCraft does not place
a specific battery or batteries in the boat. The company strongly
encourages you to discuss your battery options with your autho-
rized MasterCraft dealer prior to purchase. All batteries must have
750 CCA (cold cranking amps). Less can result in too-fast battery
discharge and may leave boaters stranded on the water. AGM spiral
cell batteries are recommended.
Review all electrical information provided in this Owner’s Manual
prior to first time operation of the boat.

Troubleshooting
Because battery needs can vary substantially depending on a num-
ber of factors in usage from boating locations to number of electri-
cal components on the boat, MasterCraft does not place a specific
battery or batteries in the boat. The company strongly encourages
you to discuss this critical matter with your authorized MasterCraft
dealer prior to purchase and placement of the battery in the boat. All
batteries must have 750 CCA (cold cranking amps). Less can result
in too-fast discharge of the battery charge and may leave boaters
stranded of water. Spiral cell batteries are recommended.

DUAL BATTERIES
Models
All
Purpose
Because of the demanding drain on the electrical system by
modern MasterCraft boats, it has become necessary to implement
a dual battery system. When properly operated, the system will
allow the boat engine to crank over with immediacy and support the
various entertainment options on-board.
Location
Two batteries function from a dual battery switch, which are located
under the port rear storage seat in most models. See the Guide
to Individual Models section of this Owner’s Manual. Battery and
battery switch locations vary by model.
Operation
For normal operation, the battery switch should be placed in the
ON position. This allows the engine and all accessories to receive
power. A running engine will recharge both batteries with the switch
ON. For transportation of the boat by trailer and during storage, the
battery switch should be placed in the OFF position to allow both
batteries to be isolated from all circuits. The COMBINE setting
LOW VOLTAGE BATTERY ALARM
Models
All
Purpose
In the event that the stereo has been functioning when the boat is
not ON and running, the voltage drain on the battery (or batteries)
may result in difficulties with restarting the boat. It may also cause
intermittent erroneous or fluctuating gauge readings. When the
voltage level reaches 10.5 volts or below, the system will shut off the
stereo and sound the alarm.
Location
Internal and unseen
Operation
Generally, the appropriate action is to leave the stereo OFF, as well
as disengaging any other peripheral electrical components, and
keying ON the engine. Running the engine at a moderate rate for
several minutes without the additional drain of stereo and unnec-
essary electrical equipment will allow the alternator to recharge the
battery or batteries, unless the battery(ies) have been used to the
extent of their life span.
