Keep us informed as to how it works out

I assume your trolling battery system is 12Vdc
Have a similar setup for external batteries from the rigs 550 watt array
The outboard motor might be of assistance - My Yamaha outboards can supply as much as 25 amps external charging current, a few switches to isolate when needed and all is good. Additionally installed a 100watt portable solar panel that can sit for hours / days on the boat to top off the batteries if / when needed.
Keep that trolling motor alive and even better catch some fish while enjoying life
