    Goin heavy

    Wanting to upgrade my boat from a 24v to 36v. Do I need to go to a heavier gauge wire if so what size?

    You are probably OK as stated above. But, I would check your manual for the new 36V TM to see what gauge wire it says you should use. Probably 6 gauge...then, make sure that's what you have.

    Id change it if you could depending on ehat gauage you got atm. About a year ago i went from 24 to 36 and i noticed with the 24v lighter gauage when chopping through heavy heavy vegetation on a 36v the wire got pretty hot. Motor was cutting through fine not struggling kn anyway but noticed the wires got hot. Changed em out and feel better about it.
    keep your lines wet! God bless

    If you're in the position to do so upgrade, when it comes to electrical work I always air on be side of caution, ease of mind type of thing in this situation.

    Check the rated amp draw on your 24v to your 36vmotor, generally you will pull less amperage on higher volts.

    Correct, and you also need less copper since you are pulling fewer amps. Here's a minn-kota chart from an installation guide. Notice that in several cases, you can use a smaller gauge wire when you switch to 36v. For example the Maxxum 80 needs 6 gauge, while the 101 (36v) says 8 gauge is required.
