Not to take away anything from Dennis' good advice, but I did exactly what you're thinking of doing on my C&C 24 and it solved my leaking problem. I actually probably went 1/2 turn (it was 5 years ago, so not sure). As Dennis said, there might be other reasons for your leak. And as for the butyl tape between the hull and topsides, when I tightened the bolts a very small amount of what looked like butyl, but more liquid, oozed out at one spot which led me to believe it wasn't in tape form. Before tightening the bolts I was about to re-bed the toe rails, which *does* have butyl tape between them and the deck, but the tightening fixed it. Ed
