Well... not quite perfect. Here is the scoop for anyone wanting to protect their T1003 power connections. They are apparently different from the power connections of the Torquedo Evolve - I say apparently because I haven't seen the Evolve, but what I know for a fact is that the caps sold by Hobie for the Evolve power connections: p/n 72021128 (Cap Assy Power Plug Male) and 72021120 (Cap, Pwr Plus, Female v1) do NOT fit the threaded power connections of the Torquedo T1003.
Note that the control connections are identical between the two motors and the caps sold by Hobie (72021124 and 72021123) fit perfectly

Thanks Hobie for making these caps available as leaving such electrical connectors unprotected on a boat is not a good idea. Hobie, can you let us know who your supplier is for these caps - I'd like to reach out to them and find out if they have the caps I need because I haven't been able to find them on the Internet.
