minn kota maxum 55

Hi guys
Just looking at possibly purchasing a used MK maxum 55 ( I currently have a motorguide 45lb-12v) but would like to switch over to MK. Was hoping to have a picture but the seller didnt make it up to his cottage to get a pic and I'm not sure how old it is.
I have heard the maxxum's were(are) great and last a ton.....oh, he's looking for 300 btw
any thoughts on the maxxum..
thanks very much guys

How old is it?

ontariobasser · January 10, 2016, 08:34:52 PM

not sure..i asked him but he didnt include that info!
I am just looking at you-tube re 12v vs 24v battery systems...i currently have 2 12v in parallel so what is the value of running 2 in series to make 24v?...if i did this , im assuming i would need a new plug, possibly new wiring?
i seem to do okay with the 12v system now (smaller bass boat)...so was just curious if i should look at 24v or leave as is..
thanks

I have a 55lb MK Maxuum. I bought mine with digital variable speed because I liked the controlled transition the motor provides on the higher settings. On a 5 speed TM if you are not careful, the TM will jerk you right off the boat. 55lbs was the highest I could get on a 12 volt system. I run this TM on a 27 series battery for 8-9 hrs and never have I run down the battery. Some of these outings were in very windy conditions.

They are an excellent TM, if you buy it run it on 12v only or you may burn it out.

thanks guys!

12V with 2 batts in parallel in theory is no different than a 24V motor with both those batts in series, albeit both motors being the same hp/thrust.

Voltage and amperage are inversely proportional. In essence double the voltage...half the current. Half the voltage and double the current.
For me, and everywhere, higher voltage is better due to it's easier and cheaper to send the current over longer lengths and smaller wires.

Hope you understand what I'm trying to convey....if not ask away and I'll try to explain.

so what you're saying is there's a chance..haha
i take it you mean you would prefer the 24v route...im still undecided about the whole thing..i would like to upgrade the boat in a year or so so i might leave as be..it works fine

Everything should be there to turn it from 12 volts to 24 volts you just have to keep in mind that it will only last half as long

Depends on the AHr it draws w=v*a

Whoa now, what do you mean by that?

The difference in connecting two 12's in parallel and two 12's to make 24 volt is this:

Pos to Pos and Neg to Neg = 12 volt in parallel

Pos to Neg on other battery and Pos to Neg on other battery = 24 volts.

A 24 volt system, while giving More Power will not draw down quicker, in fact just the opposite. 24 volt systems draw less amps, thus allowing the Battery to last much more longer.

At least that is what I have found.

You're correct and he's wrong.
For same sized load (KW or HP):

Volts and amps are inversely proportional. In other words, double the voltage and amperage is halved.

Or simply put: they will be the same.

Advantage is smaller wire required at higher voltage. which in essence means less lost to line drops on the conductors.

Thanks for confirming that.

I know when I had a 12-volt 50 lb Edge I used 2 batteries in Parallel and they did last a long longer than just one, but that was because it had twice the battery power to use.

With my new boat and a 8o lb Maximum and 2 batteries hooked as 24 volt I can go all day and it seems to barely draw them down.

For example takes about 5 hours to re-charge both batteries VS 8+ hours before.

Just be careful you don't run a 12 volt TM on 24 volts, nothing good will come of it except for the manufacturer when you have to buy a new one because you crispy fried your's.
