Think I figured out the water problem. I am pretty sure the water is coming in through the deck drain. Water is coming off the moorage roof, dumping onto the swim deck and transom. Water is getting into the drain opening in the rear next to the transom door, following the engine compartment deck lid lip to where the removable and fixed lids meet. At this point there is a dip in the lip and the water is cascading down onto the shelf, holding the water heater and batteries, and down into the bilge.
Under normal circumstances this would not happen, but when you get .25"-2" of rain the drains can't handle that much water, the boat is sitting a little bow heavy allowing the water to flow forward instead of draining our the back of the boat.
My solution is simple cover the drain on the back of the boat so water can't get in

and loosen the front tie downs so the bow comes up a bit. Our slip is only really a 25' slip so it is a little short and narrow, I have to keep it tied pretty tight to keep it from hitting the dock. I also moved it forward 10" (makes the bow pulpit stick about 1/2 way across the walk way) and that changed where the roof runoff spills onto the boat.
I spoke to Fourwinns today, they have no idea what the drain hose is for and suggested tearing the boat apart to find out where it goes

They think maybe it got a A/C drain by mistake, either way the inside of the hose is dry so that's not where the water is coming from. It's supposed to rain like hell so I should know if it worked.
