I bought a used 2007 Outback V and was concerned when I read this post. Unfortunately, the boat sat outside uncovered on the dealers lot for about 2months until I bought it. I think thats where my water came from, but could be wrong. I pulled the sac and the mat from the ski locker and noticed I had water seeping up throughout the floor. I called Skier Choice and they told me to drill 5" hole, pull the insulation, dry it, once dry use spray foam to fill the hole, replace the fiberglass piece and fiberglass it back in. I don't want to do that because I won't know if water is getting back under the ski locker. I am going to re-fiberglass the whole ski locker and seal it. Then I am going to install a 5" water tight deck plate from Overton's. I think my water is coming down through the floor of ski locker, the fiberglass seems brittle in spots. I hope this correct this issue. SC was very nice and helpful, but would not admit this is known issue with this boat.
