Had my boat now for 15yrs, every time I have to change out the trolling motor batteries I want to punch the guy in the face that designed such a limited access panel! Next boat will have better access to the bilge area or I won't buy it. Of course, I think every other boat out there has better access, so that doesn't limit my choices. Maybe one day I will get a Legend with the large bilge access panel(s) that you can open one side and be able to sit on the other lid to do the work you need to, without standing on your head or getting a whopping 1/64th of a turn on the ratchett while tightening the nuts on the trolling motor batteries.
Rant over, have a good day!
