@lexvil I really doubt they will propose to have me send it back. But, I'm going to (probably) wait for a real response from them before I do anything with it. I got a response today, but it was just an acknowledgement that they got my email and copied the right person to respond. They are shut down right, so I'm not sure exactly when I'll hear back further.
What I was thinking is, since it's in the boot, maybe just fill the boot with water and see where it comes out. Then use some Aquaseal to seal that. But, like I said, I'll wait for the moment.
It's totally diveable, like it is. In 51F degree water, I felt a cold spot when I first got in and then couldn't feel it for the rest of the day, so no big deal, really.
