Another Low oil pressure problem...

Don and All,
Since I have had my A4 (about 3 months) it has displayed 20 lbs of oil pressure at all RPM's. Last weekend I warmed her up and successfully adjusted the oil pressure to read 35-40 lbs. Great! This weekend when I got to the boat and fired her up, she displayed only 10 or 12 lbs regardless of RPM. there was no difference after cleaning the contacts on the gauge and sending uni.

This is a later model engine. It only has 20 hours on the last oil change of 30W and the oil still looks good. Compression is good too so I assume the motor is probably in good condition. What could have caused the change in pressure after sitting for just a week? Broken oil pressure relief spring? Stuck ball? Should I order the new kit that has the old style relief valve? Did I adjust it to high and break something?
BTW, this is a Catalina 27 and the oil pressure adjustment is very hard to get to. Thanks in advance for you help.
