I was running offshore and at the 12 mile mark I received the overheat alarm. On Starboard engine three oil level indicators flash. Alarm was silenced when I put both engines in neutral. Continued to run and repeated the scenario (3) more times after about ten minutes of running time. Even at *****ing speed after some time the overheat (constant alarm) sound was heard.
Started to run back home and was able to determine the following: Overheat alarm sounds after ten minutes (almostly exactly on four occasions)of running time; alarm is silenced when each engine put in neutral; continue back to running the alarm sounds; turn key switch on starboard engine to off position and can run for ten more minutes before alarm sounds; again at ten minute mark get alarm; if *****ing speed for 5 minutes and then start running after restart alarm will sound in less than 10 minutes
Water coming out of exhaust fine, out of teltail fine and shafts do not feel hot, oil level OK
What is the problem - thermostats, oil sensor, overheat sensor?
