4-Tec 185 1503 block crank line size?

[Janiporo]

Sea-Doo 4-Tec 185 1503 engine in question.

Can someone give me absolute measure in millimeters for this crank line hole diameter (A)

I received mismatched pair and need to machine it, since it is oval now (too tight).

My machining shop needs accurate number to work with.

Thank you very much!

It is now machined to 54.05 and I assembled the lower half of the engine, and it seems to rotate with ease.
