Turn the engine OFF, as well as any systems that are operating on the boat.
Make sure the battery switch is in the OFF position.
Loosen and remove the negative (-) black terminal connection first. If you are using
a wrench for this process, be careful to avoid touching the positive (+) red terminal
connection as you may receive an electrical shock as a result.
Next, loosen and remove the positive (+) red terminal connection.
Disconnect the hold-downs that are holding the battery in place.
Remove the battery.
Using a battery terminal cleaner, carefully clean the corrosion/debris from the
battery posts.
Using a baking-soda-and-water mix, clean the battery case, taking care to avoid
splashing any of the solution inside the battery vents. Rinse with clear water, again,
avoiding the vents.
Inside the battery is an electrolyte fluid that allows the chemical
reaction to provide power. The fluid is comprised of several components,
one of which is sulfuric acid. As with most acids, this is caustic
and corrosive. If it comes in contact with skin, immediately
flush the area with copious amounts of fresh, clean water.
Follow up with medical assistance.
A battery terminal brush may be necessary to remove corrosion from the inside of the battery
terminals. Use the same type of baking-soda-and-water mix and rinse with fresh water. Dry with a clean
rag.
Check the box in which the battery is held to be certain that is not showing signs of corrosion or dirt.
Clean, if necessary, as with the above instructions for cleaning the battery. Be sure that the holding box is
dry prior to reinstalling the battery.
Repeat with the steps with the second battery.
After placing the battery back in the holding box, reconnect the hold-down. Then reconnect the
positive (+) red battery cable connection first. Follow with the negative (-) black battery cable connection.
Tighten both terminals and then coat with a thin covering of marine dielectric grease. Be sure that the
positive terminal rubber boot completely covers the terminal.
If it becomes necessary to re-charge a battery from an
external source, DO NOT attempt to charge using automotive
battery cables or use another boat battery as the source
for charging. Some amounts of hydrogen gas are emitted
during the charging process. This can be very dangerous. It is critical to keep all sparks,
including smoking cigarettes, lighters or any type of flame, well away from a charging
battery. Use the optional battery charger sold by authorized Axis dealers, or a similar
aftermarket battery charger. Using the wrong type of charging procedure or improperly
charging a battery can result in an explosion and/or fire that could lead to serious injury
or death.
An unexpected or strong odor can be the first sign of leakage. Both exhaust and fuel leaks have
distinctive odors and should never be ignored. If either is present, do not start the engine until the source
of the odor has been determined and corrected.
Because gasoline is highly flammable and vapors are more
dangerous than the actual liquid fuel, never introduce flame,
spark or electrical ignition into an unknown source of a fuel
emission or leak. Always verify the source of and correct any
leakages prior to use of the boat.
