Trolling Motor 12v to 24v

Recommended Posts

Hello everyone.  My 42lb thrust motorguide's steering cable broke, which I am thinking is going to be a blessing in disguise.  In NJ my primary lakes i fish in it are electric motors only, so I upgraded to a 70lb thrust Minn Kota Maxxus!  I just need some help on a couple of things.  First off I have three 12v batteries set up to ProMariner ProSport 20plus 3 bank 20 amp battery charger.  I am under the impression I need to change to a 24 v system I run the + to + on circuit breaker then - circuit breaker to + on battery 1, - on battery 1 to + on battery 2 and - on battery 2 to - on the trolling motor. Please see my Imgur album http://imgur.com/a/Rbuk9 to see a diagram of what I am talking about and all pictures.  My first question is when I connect battery 1 to battery 2 what wire am i using?  Same for the - on the circuit breaker to + on battery 1.  Do i need a specific circuit breaker or will the 50 amp one I bought at West Marine work?  My next questions is I currently have a switch that has options 1, 1&2, and 2 this controls what battery my previous trolling motor was using.  Do i need to do anything special with this?  From what I understand there is no battery 1 or battery 2 they have formed a super batter now (24v).  My next question is I have seen the Minn Kota power cords I believe which have 3 prongs based off the youtube videos I have watched.  My power adapter is 4 prongs from my Motorguide motor.  Do i need to purchase a new power adapter or do something completely different to make that work?  I think that is everything, any help would be greatly appreciated guys.

Your diagram is right.  And the 50 amp breaker should be fine.  I ran a setup like that for 2 years on my bowfishing rig.  As far as the battery switch goes, I have no clue. And I've never ran a power cord either. Just wired from troller straight to the battery.

Your on the right track. Get rid of the battery selector ( no need for I ). 50 amp is the correct breaker.  A 4 or 6 gauge wire should work between the batteries. I'm assuming you have 2 wires running from your trolling motor. If you do, you can use the same plug. MAKE SURE when you wire the plug, that you have neg to neg and positive to positive when the plugs are connected. Use this page (https://www.minnkotamotors.com/Battery-Selection-Rigging/) to determine what size wire to use from the battery to the trolling motor. Hope this helps

Bass Pro sells a power plug that will plug into your old Motorguide outlet.  It comes with the necessary shrink tubing crimps to crimp onto the Minn Kota power wires.  There should only be two cables on the Minn Kota you need to hook up, a red (+) and a black (-) wire.  The other two prongs aren't used, or at least they weren't on my Maxxum I upgraded to.

I put a link to the one that I was talking about in my previous post, or at least that's the one that my motorguide used.
