Default Re: Water Pressure vs Water Temp gauge

...after the poppet opens (about 3k rpm) the pressure should drop to about 8-12 psi and stay there all the way thru WOT
Mine ('92 Merc 150 carb) drops from about 38-40 psi to about 16-20 psi at between 2800 - 3400 rpm when the poppet opens and then stays pretty constant to WOT. If your pressure drops below 8 psi at any time you have a problem.
