outside diameter of my OMC risers and the ?Y? pipe inlet that goes to the stern drive

[Black as]

Hi Guys

I have a picture here of what I plan to fit ?diverter? the best of both worlds.
What I can?t seem to find is the outside diameter of my OMC risers and the ?Y? pipe inlet that goes to the stern drive. I?ve searched for drawing details and still no luck, I don?t won?t to pull mine apart as yet until I?ve done all my research. I have a 1988 Bayliner Capri with a 350 chev and Cobra stern drive

Can anyone assist me with this information?
