update on cb leak fix
This is an update to previous postings and the link indicating a fix using a 3/4" x 1" nipple to fix a leak of lake water from the centerboard trunk into the bilge on Daysailer II's. The top hole (centerboard downhaul) does not appear to be an issue. It is upright, and the filler material between inner and outer molds is in place on my boat. The hole is shaped like the upper half of an hour glass. The lower hole is 3/8" wide and the upper portion is 3/4" wide. It is 1 1/8" from top to bottom. A 1/4" inch line passes through here. Any water splashing up, likely drains back down into the cb trunk.The lower hole is horizontal, but does not have filler material, and is likely the source for water entering the bilge. Otherwise it is of similar configuration to the upper hole in dimension.A threaded nipple, properly siliconed or epoxied would likely affect a proper fix, but here is the controversy. Would this divert water into the cuddy instead? I had thought of making the nipple slightly longer and putting an end cap on it, with a 3/16" hole in the center, just large enough to allow the wire to pass. This would act as a dam and encourage most of the water to flow back into the cb trunk.I am thinking that the lack of filler material in the lower hole was actually designed this way, and perhaps SHOULD NOT be fixed. If you have a DS II in your driveway, a mirror and flashlight, I would appreciate your comments on what you see. You will need to pry off the donut with a screwdriver. It came off relatively easy without damage. Here is what I saw...
