Re-Activating the Boat
After Storage
Step 1:Removetheducttapefromtheexhaustaps.
Step 2:Fullychargethebatteryandinstallitintheboat,followingall
safetyprecautionsassociatedwithchangingbatteries.
IMPORTANT NOTE: Often, batteries that have been stored over winter
will require re-charging. If the battery is charged by utilizing a battery
charger, use only a three-stage or more battery charger. It is important
that the operator never turn a battery charger immediately to “start,”
as the sudden jolt of voltage may cause damage to the electrical system,
particularly control modules for ballast system. Regardless of whether
it is during the re-activation process or at any time, care should also be
used in charging the battery.
Step 3: Followallinstructionsforreactivatingthedrivetrainasdetailed
intheengineowner’smanual.NOTE:Duetothecomplexna-
ture of the reactivation process, MasterCraft recommends hav-
ing an authorized MasterCraft dealer perform this function.
Step 4: Ensure that all drain plugs throughout the boat and drive train
have been reinstalled to avoid unwanted intrusion of water.

ring to ensure a working connection.
