yea the Drive unit Rebel Bay has is the same for the Key West Cat..the unit i picture is for both single and duel motor setups, single being the standard and duel speed was the hopup option...
but you can adapt any drive unit for the Systems Cat, im just not sure what to use yet...and the single aluminum rudder just doesnt do anything for me, i need to think about the drive units too before i cut & build the boat, the top round motor hatches will be removable and will open like the real Cat.. i hope..

I may modify two gtx650 outboards, drilling straight through the prop mount to the back, adding tubing and teflon flex, and remove top cover.. like in my mock picture here..it will look like this..
