That extra stuff goes on the shred pile, general term for mostly steel which can contain a fair amount of other material. Its where you would have put the trolling motor had you not broken it down. Go to the salvage yard once and you will understand.

I am impressed you were able to figure out that the silver colored wire was tinned copper. Tinning makes soldering easier. You did well so go hammer something else into summission, er I mean beat the copper out of it. Mike.
