Search X2 Guy's posts on PWVToday. He had a piece on an X2 that set the pump back. I don't know what to tell you about the ride plate mounts. On all Kawies I have seen inside of they have a stainless steel nut epoxied to the hull. Well that nut rests inside the fiberglass. So unless you use a custom plate with some hull inserts, I don't know the best way to do it.
