You would find the same thing if you tested that way on the positive side.
Either something is turned on, something normally running, or you have a
short somewhere.
As for the pitting, it may be due to no or wrong sacrificial anodes
installed.

I have a 2002 Smokercraft. I was doing some testing for my
downriggers and I noticed I have a negative flow through my boat. Is
this normal? I found this by un-hooking my negative lead from the
battery. I then hooked a test light between the post and the hull and
it lit up. Do I have a problem? I also have some small pitting above
the waterline, could this be linked?
