You will need a strut, rudder, a bracket for each, a flex cable, teflon liner, sturring tube, motor coupler, and some 1/8" ply to put inside the transom to reinforce it, and some epoxy to glue everything together.

Go to the OSE (off shore electrics) forums and read about how to install everything. (there isn't going to be anything about the apache, but it's basically the same for all single drive cats.)
