Just in the slip the last 3 times. Weather wasn't good to go out.

You'll need to test it at sea fully warmed before anything can be concluded. I suspect it will still alarm and the gauge will read low. What pressure is the gauge showing with the alarm sounding?

It has been a week since it went off--but I believe it was at 40.

If the oil presssure was at 40 psi I would ck the three switches that control the warning alarm! Oil Pressure N-C switch near oil filter ( not the one for the guage), Water Temp on T Stat housing gain not the one for the guage, and the out drive lube bottle!
Those are the only ones that would set off an alarm!
Good luck!

Don is correct; 40 psi is not low therefore you need to isolate which of the three sensors is setting off the alarm. Try disconnecting them one at a time until it stops alarming and you found the issue. The lube bottle is know for getting stuck but the oil pressure one is also know to go bad.

Getting the oil up to temp where it will thin out and drop pressure some also takes 2-3 times longer than just getting water temp up to normal. That could be 20-30 minutes just idling in the slip.
