I started with a short length of mechanics wire, poked it down the drain. After about 4 " it seemed to be free of the foam. I opened the ski locker and could see the wire when I stuck my head under the deck. Grabbed a steel coat hanger, ran it up and down the drain hole, problem solved. There is a good 3 to 4 " of space between the bottom of the foam and the hull.
Thanks for the tips
