Thoughts on what the GPS/power problem might be?

Most give an indication when power switches from external to battery,
newer Lowrance models even read out external voltage. Do you see this
indication when plugging and unplugging external power? Make sure your
outlet is still putting out power like you assume. A buddy of mine has
one (Lowrance 100), but doesn't have the adapter so I couldn't verify
this...

I have a Magellan GPS that will kill any batteries (2xAA) left in it, in
a matter of days. One possible reason is that the internal lithium
battery has failed and its trying to maintain memory and other things.
However if it has external power, it won't run the internal batteries
down. I just never use it anywhere where it has always on power,
everything gets turned off with the master switch. I simply pull the
batteries out everytime I'm finished with it for the day. Drawback is
that you have to initialize it everytime you want to use it...

I have a fear that our Lowrance 2000C could cause the batteries to leak
in it, so they come out everytime it won't be used for more than a
couple of days...
