Recently I had my engine go into engine protection mode on two different occasions.
This happened one time about 2 months (5 uses) ago but the problem went away after putting the shifter in neutral.

However this weekend the problem would not go away until I shut off the engine. I dropped the anchor and did a very brief inspection to see if there was something obvious that was wrong. Could not see anything. When I started the engine to head back everything seemed ok until i got up on plane and hit some chop and the engine went back into EPM. In fact the times that I have had the problem it has been when the boat has bounced in the chop. When I got home I put on a code reader but the ECM had no stored codes (all 12s).

I should also point out that the gauges report 140F for temperature and 60psi on the oil pressure.

Any ideas of what I should do next.
 
"I had a problem such as yours

"I had a problem such as yours in a new 2007 Monterey 5.0GXI,,My gauge for water temp, was way off and went into EPM, The second time the gauge was reading 230 and no EPM,,,Have this checked out by a VP repair shop...I found that VP 5.0 GXI alarm will sound and go int EPM at 205degrees,,The computer reads the motor and system not the gauges,,,so you may be overheating or have low oil pressure without knowing it if your gauges are way-off..Be safe and have it checked..."
