I have been out of the water for 2 months very little rain and i am pumping out gallons of water out of the bilge, wait about a day or two can pump out another gallon or two. I have put the inner hull drain and never really got any water from it just a little cap full and dripping. I plan to put the boat in the water and pull the floor out to see if i can see water coming in, i know when i come in from fishing i pump out at least 10 or more gallons out of the bilge. I would like to know how many drains can i put in for the inner foam. Well looking at it from the bright side if the inner hull is holding water and leaking into the bilge i probably don't need any more drains just need to find where it is entering. Sorry for so many questions in one post just need to stop the water so i can have a great fishing season with little fustration of having to wait at the ramp while the dual pumps pump out the water.
