Hydro generator

Hello,
I want to build a hydro generator and I ='m looking for an alternator with a planetary gear.
I found out you have many planetary geared motor but I would like to know which one would be the best considering:

  • it’ll be submerged in salted water. ( but I can waterproof my self)
  • You need stainless in slated water.
  • The propeller don’t turn very fast ( max 500 RPM ) ( I’m aiming for 250 RPM )
  • I want to charge a battery so I need in output around 10Ah or more.
  • I want it to be brushless.

Do you have any motor wich would answer these conditions?
Or do you know where I could found one?

Thanks.
