This is happening enough that I believe we may need to take it up with FAE themselves. My top bolt also broke last year and I replaced all three this past winter with 1/4"" SS. Still a constant but not dangerous leak into the bilge at the transom exhaust protrusion. I've tried extra "crank-down" and silicon and don't understand why the water intrusion is still occurring. It also looks like a weld crack where the pipe meets the FAE flange. Could be surface only but definitely a bit worrisome.
