I am trying to install a trolling motor on my first boat (1999 Sylvan ProSelect). First issue is that plug and receptacle are not compatible, so I assume that I change the receptacle? The other issue is that there is a switch that activates battery one or two for the TM. I have a 36v trolling motor, so I will need to wire to two batteries. Not sure if I need to disable the switch or can just run both batteries on battery one?? Appreciate any advice.
