system shuts o the stereo and sounds the alarm for a period of 
one (1) minute. In this event, return to shore as soon as possible 
and seek assistance from an authorized MasterCraft dealer.
BATTERY CHARGER
Models
 
The engine exhaust system emits carbon monoxide, a toxic 
substance which may cause serious harm if inhaled. For this 
reason, never run the engine in a confined space or any location 
that may entrap fumes. You should also avoid running the engine 
whenever the boat is stationary in calm wind conditions. 
OTHER ALARMS
Models
All models feature various alarm systems monitoring oil pressure, 
engine, and transmission. 
Purpose
The alarms take readings from sensors that monitor oil pressure 
and engine/ transmission temperatures. If an issue is detected, an 
alarm will sound as a warning to the operator. 
Location
All alarms are internal and unseen. 
The battery charger is optional 
for all models. 
Purpose
The optional battery charger repowers the battery and extends 
battery life while the boat is in storage. It belongs to the triple-
stage class of electronic chargers. These chargers are lightweight, 
silent, and completely automatic. Unlike most automotive 
chargers, they do not boil o electrolytes from batteries that have 
undergone proper maintenance and installation.
