What is the operating range for the Raw Water cooling pressure for a Mercruiser 6.2 L, 377-320 hp using a sender part number 8M6000623? At what pressure does the alarm go off sending the engine into Guardian mode?
Thank you..

I am working on a high pressure alarm on my 496's right now that use that same sensor. My alarm trips at 41 psi at WOT on a Rinda scanner. Im not sure what the Merc spec is. My other motor runs at 35 psi at 5000 rpms with no alarms. See my post from yesterday.
