Another boat question

Yes sir x2. I wasn’t going to try the tank but anywhere there were stainless steel screws, there’s some pitting in the way back. Looks like some junk under it too so I’m checking for bad chafing.
So far no pits in the outer plates.
I’m taking it in for a couple cracks up front.
Some advise: don’t force them in choppy water, you’ll pay for it! Take ‘er easy out there.
