Sun Cat Water Leak Fixes  Posted By: Dick Herman, Sun Cat “Muddy Duck”  To find water leaks in a Sun Cat first, check the drain outlets in the stern, especially the lowest three. Make sure they are  all sealed. Second, check the cockpit drain holes on the floor of the cockpit. There are two of them in the forward corners.  Unscrew the drain grates and make sure they are sealed. Third, check the centerboard bolt that the centerboard pivots on.  It may be as simple as tightening the nut. I had to replace the gaskets which are pretty easy if you think it through. The  photos are to help you with the location. If the above doesn't stop the water, you've got a little project. I've included a photo to show you where I found a major leak  in the centerboard pennant standpipe. That’s the line that comes up through the floor of the cockpit through a pipe that  you raise the centerboard with. You have to remove the teak block and make sure the hole is sealed. 54
