possible and seek assistance from your authorized MasterCraft
dealer’s service department to diagnose and, if necessary, repair
the problem.
BATTERY CHARGER
Models
All, as an option
Purpose
As a convenience, a battery charger is offered as an option. The
charger is designed to recharge the batteries and also to extend
battery life in applications where the boat is stored.
These are three-stage electronic chargers, completely automat-
ic, lightweight, and silent. Unlike most automotive chargers, this
charger will not boil off the electrolytes in properly installed and
maintained batteries.
Location
See the Guide to Individual Models section of this Owner’s Manual.
Battery locations vary by model.
Operation
The red and green LED lights, which are mounted on the charger
face, indicate when the unit is recharging and maintaining the bat-
teries. The battery charger will shut off when the batteries are fully
charged.
Before charging a battery, do not operate the charger if the cables
or an LED is damaged. Be sure that all accessories are OFF.
If the battery or batteries must be removed from the product,
always remove the grounded terminal from the battery first. Be sure
that the area around the battery is well ventilated while the battery
is being charged. Also ensure that the battery terminals are free of
corrosion. (See the Scheduled Maintenance section of this Owner’s
Manual for additional battery information.)
Carbon monoxide is emitted from the engine’s exhaust system.
Never run the engine without proper ventilation. Do not run the
engine in a confined space or where fumes may be trapped. Do not
run the engine when the boat is stationary in calm wind conditions.
OTHER ALARMS
Models
All
Purpose
Sensors check the oil pressure, engine and transmission tempera-
tures.
Location
Internal and unseen
Operation
If the system detects readings outside the acceptable range, the
system shuts off the stereo and sounds the alarm for a period of
one (1) minute. This signals the need to return to shore as soon as
Troubleshooting
If the battery charger ever appears to be malfunctioning, see your
authorized MasterCraft dealer for assistance. Repair or replace-
ment of battery chargers should be done only through the dealer.
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 result in death or serious
injury.
