The propeller which Tereza use now is working, but I was all the time looking to reinstall the original propeller.
And finally I have find someone to whom I did trust.
It is at Vacamonte puerto in private boat yard.
In my case the owner: Ing. Alejandro Gerbaund did personally take care about it.
It was time to repare it from december 2014.
Here is link to that accident.
