What was it

[dogwspts]

One of them things. Sensor blocked water passage somewhere, Air drain system not seated closed. Had it out twice on issues . Not saying it wont happen again.

Still not sure what the block pressure should read. Also will it change after a long run at same RPM.. ?????

Not sure if this helps Dwp but took some screenshots of my block pressure while on the lake yesterday. This is for a 2005 496 mag HO mated to a BIII outdrive.

Idle RPM = 2.6 PSI.....
