Minnkota Edge 55# 12v is tripping circuit breakers

[moi]

Assuming a 50 amp load, if #8 wire is used there is a 0.512 volt drop, if #6 wire is used there is a 0.32 volt drop. Change the breaker & leave the #8 wire, imho.

You most likely know your numbers way better then me but could you show or tell me the math you used to get those numbers?
I'm not being sarcastic,just wanting to know.

I am way higher,same with the minn kota site.

No problem, I used the chart/calculator on this site. https://www.stealth316.com/2-wire-resistance.htm
Easier than doing the calculation.

For the length of wire would you(/do you?)put 20 / 40 feet.
The total length would be around 40 foot?
Going by the powerstream site(at the bottom)theres a calculator as well,explains the length as the total length.
I'm just wondering if it's 40',for the pos.and neg. wire?

I estimated just the 20 feet. I also considered the resistance per foot of the different size wire and felt instinctively that there just couldn't be any "significant" voltage drop. I suspect that if there was any serious voltage drop the trolling motor wire harness would be heating up as well.
Not sure why the numbers aren't closer on the powerstream site. Haven't tried to figure it out.

I was thinking 40' because the neg.side is part of the loop.
I don't know if thats right,was just trying to find out for sure.
Thanks for your replies.
