Changing values for a raft

I am 100% new to modding. I am trying to create a raft, I have it working in game as far as being able to change the raft name and all. But the descriptions in the Bp_Raft are terrible. I believe I have the height (Max Saddle Structures Height) and amount of structures I can place (Max Saddle Structures Num) set, But I cannot find , for sure, where to change the speed, Distance from platform, camera view distance when mounted on the raft, and how to go in reverse. I have been searching and searching, any help would be greatly appreciated.

Thank you in advance!
