Looking for underwater props polisher grinder. Can somebody give an advise. Hydraulic or pneumo or waterpressure grinder type will be suitable.
I've never heard of polishing props underwater, or even out of the water if we're talking about standard bronze inboard propellors. Why would you want to polish them? Most divers clean them with a stiff putty knife and off you go.

Actual polishing to a mirror like finish, on anything other than surface drive props (Arnesons etc). No, but I see from your links that it is done. Here in South Florida I've always seen them just manually scraped with putty knives and possibly cleaned with 3M scrubby pads for decades by divers. Heck, they even come back from Frank and Jimmy's or Lauderdale Propellor as somewhat rough bronze propellors not super smooth. I'm talking about standard bronze or nibral imboard propellors.
