Detroit 8.2T-250 hp. Twins in my boat. Recently I am getting an alarm/buzzer from port engine. Doesn´t happen at startup. Once she´s under load and at temp, alarm/buzzer starts in at both lower and upper helm.
What I can say is that gauges at lower and upper helms match in terms of oil pressure and temps (all good readings). I have good water flow out the exhaust. The buzzer is at both helm stations. No visible signs of leaks anywhere in the engine room.
Is there a ´bolt on´ alarm/buzzer on the engine itself that can go haywire? Why would it be silent at idle but once underway, it starts in?
In reading posts on TF, it crossed my mind of a possible high water alarm? The alarm buzzer is the same sound that is made when key is turned to 'on' position and goes away once engine is started.
Thanks!
