I noticed last weekend that a rotted, small chunk of wood fell to the ground while I was hooking up the transdom straps. I could not figure out at first where it came from, then I looked at the bunk right above where it came from. The bunk is covered with some type of outdoor material & when I peeled it back a bit I saw the crappy rotted wood. What do I use to replace the bunks? Are the bunks like 2X4's covered in outdoor material? I guess I'll need to splash the boat & tie it up to the dock at the public launch & do it in the parking lot I guess. I don't know how I could do it at my house in the driveway with the boat on the trailer, any ideas??
