I own a 1982 Hunter 30'. I have a small leak in the pressure block area. The pump handles it fine --- but now the pressure block is falling all apart. It looks to be three similar size blocks of wood wrapped by a metal strap. I would like to replace this mess with new wood. I was wondering if any other owner has replaced the wood and can it be done without taking the vessel out of the water. I am convinced that the leak occured when the boat was taken out of the water. Prior to painting the bottom there was no leak.
