Hello,
I have a 1983 Catalina 30 with M25 Universal diesel. Earlier in the season we ran out of oil, alarm came on and we shut the engine down as soon as we noticed the alarm. Got back to port, which is a long story, and found that there were two gaskets on the oil filter; not recommended. Anyway, changed the oil filter, put in new oil, new impeller, new fuel filters and went back out. No issues until we went to anchor. Put the rpms to idle to anchor and alarm came back on. Checked oil levels and it was fine, water was coming out the back and temp seemed fine. Since then the engine has run fine at cruising speed, with no alarms, and will idle cold at the dock with no alarms either. However, every time we run the motor to our destination (usually about two hours of run time), go to anchor or when we come back to the dock (again after two hours of run time) we get an alarm at idle rpms. Right when we need it the most. Any ideas what could be causing the alarm to come on? Please don't say oil pump...maybe a sensor? maybe the alarm panel?...any help would be greatly appreciated.
