Pipe diameter question?

[Oscarpop]

Any idea what the internal diameter of a Yanmar seawater intake pipe is?
( the one from the seacock to the engine)

Is the 36 hp one.

Can't see a 36HP inboard, but if you go this page:

Pick your engine from the drop-down list; then click on the icon under pdf against 'Technical outline drawing' you will get a dimensioned drawing of the engine which includes cooling water inlet sizes. (The 39HP one says 26mm spigot diameter).
