Bilge help

[Eric B]

OK I need some advice for those of you that have had a hull stripped down to nothing (Kmoose) and others!!

I have realized that the port side of my bilge is holding water and not draining to the drain in the stern. I have a pump on that side but the water that it cannot get stays put.

I figure there must be a clogged drain or pass through in the the main keel stringer but have no idea where this is having never ripped my boat down to zero.

I have included a couple pics but they do not reveal much. If anyone knows of this issue or can enlighten me to where this water should be draining I would most appreciate it!
