What it is the normal oil consumption for a Yanmar 2GM20F engine? Is 14ml per hour normal or excessive?

My 2GM20 raw water cooled has barely moved on dipstick all time I used ... and that's about 230 hrs ....
I have to admit that I was lazy start of 2025 and forgot to change oil .. so those hours are 24 - 25.

Before you panic , just wait to see if the level falls and then stays at that new level.
That is what my Yanmar does. (Not a 2GM, though)
At oil changes I fill it to the required quantity, Which is near the top of the dipstick "F" level.
A week later it is down and then it never goes lower than that new level.
I check the level every outing just in case.
