Minimum water pressure

[teamnitro]

I have a 2001 Merc. 200 EFI. I need to know what is the minimum water pressure to watch for when running full throttle? I am trying to set up my jack plate and I need to know just how high I can go.

Well I wish I could say it was cooler. I live near San Antonio and fish mainly South Texas. Let's see...typical water temps in summer mid 80's to 90. Air temps upper 90's to over 100.
At least we don't have quite the humidity you typically have in Houston.
Thanks for the reply
