where battery capacity drops below 75% before recharge, it is probably less
expensive to provide a separate battery bank dedicated to the thruster.
The cable gauge, CCA and circuit protection already in place for the windlass must
be compatible with the thruster in order for this approach to work. We do not
recommend using windlass batteries for our SS340 or SS350 bow
thrusters. See table below:
Table 1: Shared Battery Requirements
Cable and Terminal Requirements
Due to the high current load drawn by the motors, it is essential that the correct
type of cable and connectors are used, and that maximum cable length guidelines
are observed according to the gauge and thruster model. These guidelines are
summarized in the table below. The table assumes cables from the thruster to the
controller have not been shortened.
Cable must be high quality tin coated copper, marine grade cable. Cable ends must
be fitted with high grade cast copper, tin coated terminals and sealed with double
wall heat shrink tubing for moisture protection.
