If you are searching for the leak in the water hoses I suggest you start by looking at the shower manifold. I have already come across 2 Hunter boats leaking at the connections of this manifold. That is 50% of all the Hunters I have boarded. Apparently Hunter Marine did not sufficiently tighten the screw connections to the manifold. The push fittings of the Pex tubing were done OK, but not the screw fittings. I had loose screw fittings on 2 different places on my Hunter 38.
