i have one on my boat.... but its not for sale. its made by super jet, i know i saw a place somewhere online that had there catalog up, but i dont remember where. it would not be hard to build one like it at all. its just a flat plate of alum. doesnt have any reineforcements. the transom adapter has a place on it to mount to, i dont know if the holes are already drilled or what. i guess i will have to take a pic to explain it.
