I have an old Aeromarine Shadow hydro that I am building as FE. I already have the two motors listed below and plan to use one of them on this project. Hoping for 60-70mph range. Any recommendation on ABC or Octura props would be appreciated.

HET 700-98-1170kv

HET 700–98-1270kv

I will be using either a Swordfish 8s 200a or 12s 240a ESC. Haven’t made up my mind. Thanks for your help.
