Section 6 Boat Maintenance
Remove the batteries from the boat during cold
weather or off-season storage. Always protect the
batteries from freezing temperatures.
You must not allow your batteries to become com-
pletely discharged. As a battery discharges, the active
material on both positive and negative plates changes
to lead sulfate, causing the plates to become similar in
chemical composition. The battery electrolyte
becomes weaker and the voltage drops. As the bat-
tery remains discharged, this process continues until
recharging the battery becomes impossible.
If the battery does become discharged, be sure to
recharge it as soon as possible. Overcharging a bat-
tery can also reduce its effective life.
Cleaning
At least once a year, or when they appear to have dirt
or corrosion on the terminals, the batteries should be
cleaned. To clean the batteries, turn the battery OFF-
ON switches to the OFF position. Disconnect the bat-
tery cables from the terminals.
Remove the negative
(black) cable first. Remove the battery from the plas-
tic battery box. Clean the terminals and casing with a
solution of baking soda and water. Use a soft wire
brush on the terminals. Do not allow the cleaning
solution to enter the battery cells. Wipe the battery
and terminals dry with a clean cloth. Clean the battery
cable ends in the same manner. Connect the cables
to the appropriate terminals and coat the cable con-
nections with heavy grease.
Connect the positive
(red) cable first.

WARNING
Always wear eye protection when servicing
batteries. Batteries contain sulfuric acid, which
can cause serious injury. Avoid contact with
skin, eyes, and clothing. If contact occurs,
immediately flush the affected area with water
and call for medical assistance.
