    Going from 12v to 24v trolling motor

    Do I need to run a new line set up to the front to handle the extra voltage? Is there something I should look for to be sure I don’t need to?

    Often a 24V motor can get by with smaller wire than a 12V motor. What size is the wire that is currently in there, what size breaker or fuse is there and what specific TM are you going to?

    I will grab some pictures tomorrow when I’m installing the front bow fish finder.

    Also, not sure one what TM to get yet. I know i want Link 24V 60" just not sure about Terrova/Ultrex/Ulterra I have an extra DI sensor from the head unit i bought used so i was planning on just putting that on the TM, but if it comes with a DI i wouldn't mind.

    It looks like its some thicker gauge wire running up to this socket. the socket says 12v-24v So I'm guessing i would be fine upgrading and just adding an extra battery.

    Guessing isn’t really a good plan unless you want problems on the water. Simple to read the size off the wire and fuse/breaker.

    Looks like 6 gauge, and that would be fine. You may need to change the breaker at the battery compartment depending which TM you're changing to, and the amperage for your new 24v TM. Most 12v TM used a 40 amp. If you're just upgrading to a Fortrex I'd go with a 50 amp, if to an Ultrex, go to a 60 amp.

    You need to verify pictures can be deceiving. It should say on the wire itself. Looks like 8 gauge to me. You'll want a 60 amp breaker. And find the model number on that Marinco plug it's probably only rated for 40amps by the looks of it.

    From the connections used, pretty sure that is a 6ga. 8 and 6 use the same red connections (10 and 12 use yellow), but the crimp would be more pronounced on 8ga. I would however look on the insulation and know for sure. If it is 6ga, then all you will need is the extra battery and a short jumper wire. You'll put the neg on one battery, the positive on the other and run a jumper between them, using the empty pos and neg post. You will also need to change the breaker to a 60A. hope this helps

    Thanks everyone! It will most likely be a project for next month. That’s when I take my boat of storage.
