Negative flow causing pitting in aluminum?
 

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?

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 anodes on my motor but none on my Hull. Should I add one to the transom?

It certainly wouldn't hurt. Zinc for sal****er, Magnesium for fresh water.
