186sc leaking battery compartment

[sagelake54]

Been trying to figure out leak on my 186sc. Filled boat bottom w plug in. No leaks. Dipped into lake adding hydro pressure and water seams to be coming from side. Any suggestions appreciated. Transom and side rivets all seem solid?

After three posts you can put up pictures of the area in question. Any post is fine. Let us see what you are trying to figure out. And don't fill the boat with water, very hard on the hull and trailer.
