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!
