Alarm - 1988 Mercury 175 Outboard

[jkering66]

I have a 1984 Grady White Overnighter. When I started the boat yesterday, there was an alarm/horn going off behnid the gauges. I looked under the dash, but cannot see the horn?<br /><br />What is the horn/alarm device behind the dashboard alert you of, overheating, Oil Injection alarm?<br /><br />I ran the boat at headway speed for 30 minutes and it runs as normal, great. Not sure if the alarm device is broken, or something is wrong.<br /><br />Any assistance is appreciated. Thanks.

My 1992 50HP has a buzzer that sounds when the ignition is 1st turned on. Heat, oil alarm. The buzzer is in the Throttle/shift control box tho, not under the dash. Sounds like you must have something similiar.<br /><br />Jerry

My alarm does go off when I start the boat, I assume it is to tell you that it is still working, but now it will not go off after the boat starts.<br /><br />Is this a tempature or low oil alarm?<br /><br />It goes off (Alarms/beeps) at cold tempature and I filled the oil injection tank, but alarm will not turn off.<br /><br />Thanks again.

One steady beep is overheat alarm, intermittent beeps are the oil horn. Don't run with alarm sounding. You could have a problem with the oil system. Good luck and let us know.<br />CU

My question is why would you run it for 30 mins. if the alarm was sounding? A tow would have been a miniscule hassle/expense compared with the risk of damage you took.
