Alternatively, the outboard motor can be powered by suitable deep cycle traction
batteries, sourced by the customer.
•
The table below shows the minimum battery and equipment specification required for
the different outboard motor models.
•
To stop safety risks, capacity losses and contact point losses, only the same type of
batteries (same manufacturer, same capacity, same age, and same charge condition)
should be used together.
Differences in the charge condition of batteries wired in series can
cause high compensatory currents or overloads which can damage the cables,
connectors or battery. In extreme situations this can cause fires and injuries.
•
The table below shows an example of how long the outboard motor can be used in a
specific application before the batteries will require charging.
•
Please note that boat sizes, hull shapes and battery sizes will give different results.
This means longer travel times can be achieved, depending on the application. The
following values are based on a 16ft Cabin Cruiser.
