Is there still a big difference between 12v motors and 24v motors these days
If a 12v motor has 50# thrust And a 24v motor has 50# thrust How are they
different ?

There's a world of difference between the two. While they both have 50
pounds of thrust, you'll find that a 24 volt system is more efficient and
will last you far longer on the water.

I realize that improvements have been made in trolling motor technology, but
when I had a 12 volt system in my boat, the battery was done long before I
was in a day of fishing.

If you have the room for the extra battery, get the 24 volt system, you'll
appreciate it on a windy day or in heavy current.

In the same way that an 18 volt drill is much better then a 9.6 volt drill.
A 24 volt motor will have much more torque then a 12 volt system.. It will
also last much longer between charges.

A 24 volt system only uses half the current to do the same job as a 12 volt
system, a 36 volt system uses 1/3 the current.

So a 24 volt system only needs 12 volts to do the same job as a 12 volt
sytem? Hmmm....

That is correct. If a trolling motor draws 30 amps at 12v for a certain
thrust, a 24v system will only draw 15 amps for the same amount of thrust.
This is hypothetical. In practice, it will be slightly different. That's
the advantage of a gas dryer using 240 volts rather than 120 volts in that
the amount of current will be half.

And the reason that air-conditioner compressors use 240 volts instead of
120. Less current equals lower electrical bills, and more efficiency.

I thought gas driers used gas.G

But hes,, same amount of work to be done, twice the voltage = half the
current draw. But the WATTAGE will be the same. It won't affect yo9ur
electric bill, but all the wires can be thinner, etc.

As regard the question that started this thread though, in a small boat,
if I was going to have a 50 pound thrust trolling motor, I'd use a 12
volt 50 pound motor (as a matter of fact, I do exactly that). Why would
I want the extra 60-plus pounds of the second battery in the boat? If I
have to, I can fish for 2 days off a full charge on one group 29 marine
battery and not feel ANY reduction in power. If I was running a boat
that would benefit from 70-plus pounds, I'd go to 24V in a new york
minute. But not in a boat that works fine with 50.

I think you missed the point of my post. The post I mentioned mentioned that
a 24 volt system was twice as much as a 12 volt system. I thought that a
little obvious. But it's no longer funny when this is pointed out.

Doh!!! I cannot believe I said gas dryer. I meant electric.
