I just installed an 8' bimini on my 252 Cobalt. It is all stainless with the braces that hold the bimini up like a tower. My problem is that the top really seems loose and sounds like it is going to come off. I tightened every connection. It is almost 8' wide so it is a huge top. Has anyone figured out how to brace this thing besides the back angle brace? It flops around because of the clearances in the fittings and it racks too
