I'm confounded by a pesky leak on my 2005 Hunter 36. It is a saltwater leak that occurs in the area of my thru hulls which are located at mid-ship just in front of the engine compartment. However, the thru hulls are not the culprit. I have traced the leak to the area just in front of all the thru hulls. But I cannot get access to the area I need to see. There are all these little canals with opennings that allow water to find the bilge where the keel bolts onto the boat. I have checked all the thru hulls. I'm lost. The amount of water is subtantial enough for me to be concerned.
