I'm adding an Ultrex to my 2017 Tracker 190, which means I'm adding a second trolling motor battery. The boat came stock with an Interstate SRM-27. I cannot seem to find anyone near me who has that battery. Can I use an SRM-27 battery from a different manufacturer or would I be better served just getting two new batteries (maybe 31s)?
Also, I noticed that the trolling motor wiring at the batteries is 6 gauge, but it is 8 gauge at the bow. Anyone have any clue where the change over occurs? Why would they do this...just to save on 6 gauge wire? I don't get it.
