Quick little boat battery question...

[Nainoa]

Okay... So currently I've got my boat Running with a 24 volt Cranking Battery, and a 12 volt bow mount trolling motor...

My buddy who's stuck at his wife's Niece's wedding this weekend, offered to borrow me his spare battery for my trolling motor, as I'm going to be out doing a 3 day hard core fishing expedition for opener...

His Battery is a 24 volt... Now I've run a 24 volt battery on a 12 volt motor in the past... But I'm wondering if there's any adverse side effects to running a 24 on a 12...

Obviously a 12 on a 24 system doesn't work... But is there any negative side effect of running a 24 on a 12...

As I understand it the battery should just have a lot longer life?

Your trolling motor may not be rated to handle 24volts and therefore you could burn the windings out of your trolling motor if you run too high of voltage.

Most AC voltage motors that you would use in a commercial building for example, lets you switch between voltages. There should be a nameplate on your motor that has information about it (voltage, watts, rpm etc) if you can take that off you should be able to switch two leads and change to voltage that the motor runs on. ( this works for AC motors and I am not sure about your DC boat motor.)

The first thing I would do though is check the nameplate and see if it is rated for 24volts. If it is not post the make and model of it and I'll do some research for you.

I'm just an electrical engineer but my brother is the Master Electrician so I can ask him also.

But you said that you have tried it before with no problems??

Yeah when I a problem in the main motor's fuel line, I was out in the main basin of a lake...

So for safety sake, I ran it in on the trolling motor...

The original 12 volt battery gassed out, like a half mile from the landing...

So I pulled the 24V cranking battery, hooked it up and the trolling motor worked fine the rest of the way in.

I don't know the exact model number etc... But it's a Minnkota trolling motor with 40 pounds of thrust.

Well I guess if it worked fine before I would think that it would be fine this time. But was that a different trolling motor? Anyway I would just call this number and talk to them about it 1-800-423-6569. I found it on the MinnKota website.

Yeah same TM...

Thanks Bro...
