200 hp Mercury 2.5L EFI s/n D024368. On initial startup, I dont see any water coming out the telltale. After 39 or 40 seconds, I start to see flow. Should I see water flow immediately or is there no flow until thermostats open?

Telltale comes from the thermostats- there will be (or shouldn't be) any significant flow until, or unless they are open. May come and go as they open and close (as well).
FYI: add a ZERO in front of the "D" (0D024368)

Okay. Thanks for the info. I assumed the worst when I saw no flow on initial startup.
Thank you for asking and answering this. I came in to ask this same question as I noticed this on my 2012 150 ProXS. No water for first 20-40 seconds but it sounds like this is normal.
I do have ~3 psi at idle and 11-13 on plane so I think I'm good.
Thanks

Especially important since the Optimax cooling system is different than the OP's EFI and the thermostats have nothing to do with the telltale on an Optimax.
