I am upgrading the trolling motor on my boat from a 12V Motorguide to a 24V Minnkota Terrova. I have already installed the batteries. My question is, can I used the existing plug and recepticle on the bow or do I need to upgrade them also? Do I need to upgrade the wire and fuse from the recepticle to the batteries too? Or is the existing setup ok and all I need to do is take the plug off my old trolling motor and install it on the new one.
