Battery Cable
Installation & Precautions
Your battery is an important part of your boat. It provides all
the power to start your boat and allows all of your electrical
components (bilge pump, blower, stereo, etc.) to work even if
the motor is not running.
Because of its important role, Supra recommends using a good
quality "Marine Dual Purpose" battery. The "Dual Purpose" rating
means that it can provide the cranking Amps needed to start
your motor, yet it also has an Amp hour discharge rating so it
can handle low electrical drawdown cycle.
Your Supra electrical system is a negative ground type. The
negative battery cable is grounded to the engine block. The
positive battery cable is connected to the starter solenoid.
Connect the positive (+) battery cable to the positive (+) post
on the battery. Connect the negative (-) battery cable to the
negative (-) post on the battery.
Failure to connect battery cables as outlined will damage
the system and void the warranty.

Sulfuric acid in the battery can cause serious burns. If spilled
on skin or in eyes, flush with clean water immediately, then
seek medical attention.
Hydrogen and oxygen gases are produced during normal
battery operation and charging. Sparks or flames near the
battery vent openings can cause the mixture to ignite and
explode.
Dripless Shaft Seal
Your Supra comes standard with a dripless shaft seal. If any
seepage occurs, contact your dealer.
