Re: Water in Bilge
Could be rain water from many different areas that get down into the hull. Most boats are not water tight but should be. A lot of boats will not show any water in the bilge until they get on a plane because the deep V drain to the stern is lower in the water until on a plane.
I would vacuum it dry and then test it again to see if it is continuous intrusion or just a small rain leak somewhere. What year is the boat?
Check your rod holders, anchor lockers, rub railing etc.
Is this boat trailered or left in a mooring or dock?
