I have done a few and will have to eventually on my Lund. How those idiots didn't put any sealant on the transom bolts is beyond comprehension to me, but whatever.
But like Ahab said, if you have a place it just takes time. You have to be able to unhook and lift the motors off, then store them. I built a stand to hang/bolt the motors to. That was the biggest challenge. After that, you'll probably have to grind/drill the rivets of the splash pan out to get to the back side of the transom bolts. Then remove foam to get to them. Once all the bolts are out, remove the old material as you can. It might be wet sawdust or a swelled & wedged piece. I drilled with a spade bit and then drove lags into the remaining good part and lifted with a cherry picker to pull a big chunk out. Patterning frankly isn't that hard, so if you can get a piece of composite material and can measure you can do it without too much issue. Then, just reverse the process with a bunch of 3M 5200 to seal things up.
I have "heard" that Lund was helping out the early 2000's owners by providing the material, even though there was no warranty. Anyone hear this? Mine is of that era unfortunately.....
