Identification and manuals of Ampair hydro generator

[P435]

When I bought my boat, there was a hydro generator mounted. However, not a single document was on board.
Searching the internet did not get me any information.
Now I hope that a member of this forum reads my post and can help.

I attached pictures of the hydro generator.

Questions:
What is the possible type number / name of this hydro generator?
Does somehow have and please share with me the specs and/or manual of this hydro generator?
