I'm prepping my boat for a new 80/52 Ultrex. I understand I need to upgrade to 60 Amp breakers..I noticed I have two 50 amp breakers. One on positive side of the Jumper lead and another on the positive lead to the trolling motor. Is there a reason for the double breaker system. Every diagram I find shows just one breaker on the positive lead to the trolling motor..

Post in the electrical forum, Catfan or Mr. Jones will answer your question.
The breaker on each “+” is there to protect the wiring from causing a fire in the event of a major failure.
