While trying to discover the source of an over-winter leak that flooded the boat to about two inches over the sole, I suspected a split cockpit drain hose after the many freeze-thaw cycles we had this winter.My daughter crawled into the lazarette, under the cockpit, while I sprayed a hose into the drain outlet. No leak.Next, I held the hose nozzle up to the drain outlet so the water wouldn't run out. After a few seconds, the locker-crawler yelled "Got it!"Was it the hose? NO, of course not. It was a 3/16" hole in the drain area that some PO had pushed filler into and then covered with a small piece of white Band Aid. Being where it was, I had never seen it.Can anyone beat that for a Band Aid approach?
