12 volt to 24 volt conversion

[porthos33]

Just got a 24 volt trolling motor the other day. My boat is set up for my 50lb thrust 12volt trolling motor. The trolling motor plug I am currently using is a 3 prong and it goes into the female that is a 3 prong. My new trolling motor has a 4 prong. I'm not sure exactly what my options were to set up this 24 volt system. It looks like my current wires are 8 gauge but not for sure. I have 2 new batteries for the trolling motor. Do I need to get an entire new wiring system? If so this was the only one I found and it is for a tracker 18 ft. and I have a venture 16 ft. Is this what I need or is there a cheaper way easier way? Here is a link to what I found. It runs about a $100 bucks

It may be easier to change the plug. I changed to a 24 Volt and put my old plug on the trolling motor so it would fit the plug on the dash. Just remember to wire your batteries in series to get the 24V needed for operation. Trolling motor red wire to battery 1+. Trolling motor black wire to battery 2-. Wire a jumper to the remaining two battery posts - to +.

Hey Hook 1 does there have to be a fuse between the jumper wire? or can I just use the same fuse I use on my 12 volt now?

Plug conversion is the way to go and is simple.... The last one I bought was from academy but they can be hard to find sometime. Easy to fin and order online. $25 or so

Just Mae sure the plug you buy is compatible with 24volts and that it matches up to your plugin.

So basically all I need is the female end that goes on the console of the boat changed from a 3 prong to a 4 prong>? Or I could Use the three prong plug from my old trolling motor on the 24 volt also?

Mine was only a two prong. No you really don't need a fuse on the jumper wire. You only need to make sure the red wire on the trolling motor has a fuse or in line breaker. All I did was cut my old plug off and left the wire long enough to butt splices onto the new wires. I put a long piece of heat shrink around all of it to keep water out of the butt splices. This kept me from having to change anything on the bow dash.

Regardless of the plug design or number of prongs over three, The Four prong is to be used without a battery jump wire where you have all four wires from two batteries to the front of the boat.. The easy way is to use 6 gauge wire from (-) post of Battery #2 to a prong in connector to TM. A Jumper wire of the same gauge between (+) post of Battery #2 directly to (-) post of Battery #1. Then A wire from the (+) post of battery #1 to a 50 amp breaker/fuse, Then from the Fuse block to the front of the Boat for the Positive side of the TM at the connector.. For a straight 24 volt TM two 6 gauge wires is all needed. If you have a selective 12/24 volt TM, you will need three or four wires. In that arrangement where three wires are required, then you can get away with the 8 gauge wiring you now have.. A loaded 24 volt TM under stress needs the 6 gauge for full power.. A lesser section of wire like the jump wire will create heat, blow fuses and actually cause your TM to overheat. The factory wire from your TM motor itself is lesser in size but is never an issue being at the end of the circuit. </p>

I will be glad to assist further.</p>

Sounds good guys thanks. I was going to just use my 8 gauge I have on now to get by with for a couple of months. But, if it's going to cause me problems overheating and blowing fuses, I guess I will just go ahead and get the 6 gauge wire. The cheapest 6 gauge wire I have found so far was for a dollar a foot. I can just get 2 extra feet on the red wire and use it for a jumper between the two batteries.
