NOTE: Do not use an engine starting battery that does not meet the specified
ratings. If a battery that does not meet the ratings is used, the electrical system
may perform poorly.
IMPORTANT: Boating industry standards (BIA, ABYC, etc.), federal standards,
and Coast Guard regulations must be adhered to when installing the battery.
Ensure that the battery cable installation meets the pull test requirements and
that the positive battery terminal is properly insulated in accordance with
regulations.
It is recommended (required in some states) that the battery be installed in an
enclosed case. Refer to regulations for your area.
When connecting the engine battery, hex nuts must be used to secure the
battery leads to the battery posts. Tighten the hex nuts to the specified torque.
Failure to properly secure the battery leads can result in a loss of power to
the Digital Throttle and Shift (DTS) system, leading to serious injury or death
due to loss of boat control. Secure the battery leads to the battery posts with
hex nuts to avoid loose connections.
