Sterndrive
 

Hello everyone,
I wonder if anyone can help me.
I have a 1994 Z225 with a Ford 5litre V8 on a Volvo Penta SX-M Sterndrive.
Unfortunately, the Sterndrive has failed.
Does anyone know what Drive ratio the Sterndrive is?
Yes, I know that it is stamped on a plate on the drive, but the plate is missing.
The prop is not connected to the input shaft, so I can’t count revolutions.

Any help will be very very welcome.
