Bilge

I am currently working in the bilge of my 2000 zx185. I am replacing the livewell and bilge pump as well as repainting the whole bulge area. Already removed the oil tank, gas tank, batteries and pumps and started cleaning it out. There are open screw holes in the floor of the bilge area form where everything was mounted in there. The drain plug is above this floor and I had the thought after hosing it out and cleaning it, could there be foam under that floor? If water seeped through those open screw holes would it hurt anything? Since the plug is above the floor I’m worried it can’t drain out. Thanks!

There may be foam under there. If so, it might have absorbed water, which is never a good thing. When a screw hole is no longer used, it should be plugged...either with silicone or for a more permanent solution coat some toothpicks with epoxy and jam them in the hole and when dry, break them off level.
