leak
I was sure that I had a leak in my water heater, but it turned out to be my forward hatch.There was very little sealant under the frame.I think the installer had to buy his own. Water was coming in and running forward above the headliner to the bow, running down under the anchor locker and into the bottom of the boat showing up as a puddle around my heater. Be sure before you go to a lot of work.
