Default Low oil pressure

Hi all

Went out for a cruise today and all was good.
Oil pressure at between 40 and 60.
Just as I got back to our Marina I saw the pressure had dropped to 20 and stayed there.
We had been out 4 hrs the temp gauge was fine and the oil on the dipstick is clean and full.

1992 V6 mercruiser 4.3

20 psi for an older engine fully warmed up, at idle, is pretty normal. It should come up to 40-60 while underway or above 3000 rpm. If you're getting below 20, then I'd start getting concerned.

We never get above 1100 rpm as the speed limit inland is 4 mph.
But if that seems normal I will keep an eye on it

Keep an eye on it but 20 psi is normal at low rpms and a warm engine.
