Volvo Penta 280 OutDrive Cover Screw Size?

Does anyone know the screw size for the cover on the front of the outdrive please.

Must be a very long bolt and im guessing 1-4" unc or unf?

Volvo used American standard on it's units.
I think 1/4-20 is what you need.

Checked that out by running a tap into the wire insert (helicoil) and it is indeed 1/4" unc 20TPI.

Thanks Jerry!
