24v vs 36v trolling motor for an XB 2003

[soggybear]

My XB 2003 came with a 36v Minkota with the large foot control and I am considering changing it to a newer Terrova with the copilot system but may opt for a 24v vs a 36v. I plan to enter fishing tournaments with a friend and want to be sure to have enough for long days or current conditions.
