12/24 V trollling motor

[jeepers94]

I have done a search on this and other sites on how to wire a 12/24 trolling motor. I think I pieced it all together but I would like confirmation. <br /><br />My current unit is a straight 12V (two wires only) and so is the wiring harness (two wires only). The unit I am replacing it with has three wires coming from the trolling motor leads. <br /><br />A. In order to connect this 12/24 properly, I need a third wire from the batteries (which will be connected in series) preferably 6 gauge to the trolling motor. Correct?<br /><br />B. Since its a 12/24 trolling motor does that mean I can hook it up only as a 12V? This would mean I don't have to change anything on my current set up but would I still get the thrust its rated for, 50 lbs or I would expect proportionally less? <br /><br />FYI both units are older model Motorguide units. Four-28 lb thrust and 750 Brute 50 lb thrust.

You are correct.You would need a third wire which would be a positive wire.<br /><br />Is the Brute 50 a 3-blade plug or does it have a 4-blade?<br /><br />I don't think you will get the full 50lbs of thrust off of 12v,Hence,the 24v switch.<br /><br />Tom

Stratos<br /><br />Thanks for the input. <br /><br />The 50 lb motor actually has no plug at the moment (there are three wires) that is why I was wondering if I could wire it to my existing harness with my existing plug which is two wires. <br /><br />Switch? I did not see a switch. Should I be able to switch to 24 from 12 and vice versa? Where would the switch be located.

Re: 12/24 V trollling motor

If the brute 50 is a 12/24 there should be a switch on it, usually on the head where the handle is attached.If it has a foot pedal it is usually there.It will be marked 12v one way and 24v the other.<br /><br />If there is no switch it is probably a straight 24v if it has three wires.(Not certain though.Haven't ever used a single voltage trolling motor)But I would really look at it closely.The voltage should be marked on it on the powerhead or there may be a small plate on the motor itself to identify it.<br />What color are the three wires?

Stratos, <br /><br />Your right th 12/24 switch was on the foot pedal where I was use to seeing my momentary on/bypass toggle switch. <br /><br />By the way, now that I have rewired the boat with 6 gauge wiring where do I find a plug and receptacle that accepts 6 gauge? Or at least a receptacle. The trolling motor has what appears to be 10 or 8 gauge wires (red, orange and black) So far all I can find locally is ones that accept up to 8 gauge wire. I did a search on the net and still did not find one for 6 gauge. Since 6 gauge is recommended,, they must be available. It's not a dealer item exclusivey, I hope.
