2023 OWNER’S MANUAL

 206
Operation
For normal operation, keep the battery switch in the ON position. 
Use the  COMBINE setting only in the event that a battery fails 
during an outing. When hauling the boat on a trailer or placing it in 
storage, keep the battery switch in the OFF position. 
Troubleshooting
Because battery needs can dier substantially depending on a 
number of factors (such as usage, location, and the number of 
connected electrical components), MasterCraft does not place a 
specific battery—or batteries—in the boat. The company strongly 
recommends that you discuss your options with an authorized 
MasterCraft dealer prior to purchasing a new battery. 
If purchasing a new battery, note that all batteries must have 800 
CCA (cold cranking amps). Any less may result in excessively fast 
battery discharge; this can leave boaters stranded on the water. 
To attain proper CCA and avoid potential battery malfunction, 
MasterCraft recommends AGM spiral cell batteries.  
 
Prior to operating the boat for the first time, review the electrical 
information contained in this manual. Failure to follow basic 
procedures may result in property damage or personal injury. 
LOW VOLTAGE BATTERY ALARM
Models
The low voltage battery alarm is a standard feature on all models. 
Purpose
The low voltage battery alarm protects the engine battery in the 
event that the stereo is used without the engine and alternator 
running. By automatically shutting o the stereo and sounding an 
alarm when the engine battery voltage reaches 11.5 volts or less, 
the battery alarm prevents total battery drainage. 
Location
The low voltage battery alarm is internal and unseen. 
Operation
If the battery alarm sounds, immediately deactivate the stereo 
and any other battery-powered systems that may be active at 
the time. Activate the engine and let it run for several minutes, 
allowing the alternator to recharge the battery or batteries. This 
will not work if the battery or batteries possess zero charge.
