Power is routed from the vessel’s electrical distribution panel to the drive unit through
the SPX SmartPilot.
CAUTION: Use of incorrect power cable size could cause your SmartPilot
to malfunction and will reduce the power supplied to the drive unit.
Ensure the correct size is used and, if in doubt, use a heavier gauge
cable.
You need to supply two lengths of power cable:
1. Distribution panel to SPX SmartPilot.
2. SPX SmartPilot to drive unit.
Select the appropriate type of power cable for each length using the table below as a
