I need Help. I have a 1991 Hunter legend 35.5. Here's the problem. The back two lazarettes where the fuel tank is located, water appears to be coming in from under the fuel Tank.{ 2 to 3 inches of water comes in, in about 3 hours time. pump it and it starts all over again} I have checked the thru hulls and shore water connections and water lines in that area No leaks. Is it possible for water to come in through a cracked rudder tube? Is there a fix other than cutting an opening in the the sugar scoop,removing fuel tank, lift up the fuel tank platform and remove the foam from under the platform?
