First 35/Renault Marine engine - prop sizing

I'm in the process of getting a new propellor for my First 35. The boat is of 1982 vintage, so details of the engine etc. are hard to come by, and the old prop is both badly damaged, and in Portugal, so it's not easy to measure).  I was wondering if anyone knew the standard prop pitch & diameter - or the gear ratio for the Renault Marine 4/130B?

any help with these details would be much appreciated

thanks.
