I have a 5.0 Mercruiser stern drive in a Bennington pontoon and a double tone alarm sounds as soon as the engine cranks and continues on a two minute interval until the engine is shut down. Hicks Marine came out and could not find the source. The engine is not overheating and has all fluids including the oil resevoir.
Anyone have any ideas?

There's 2 sensors that give you a ground connection to activate the buzzer which is connected to 12v any time the key is on. Oil pressure and water temp.
If you have a drive oil tank, then there's 3.
Next time you get the alarm, disconnect the oil pressure alarm switch and if that doesn't stop it then disconnect the over temp switch. If it doesn't stop the alarm then it's the drive oil level switch (if you have one). I'm assuming that your drive oil tank is full.
Any one switch will provide the ground connection to activate the buzzer.
If disconnecting all of them doesn't kill the buzzer, then you have a frayed wire touching ground somewhere.

<<<<From above quote/post. There is merit in the post. However, Evil Ghost is suggesting that someone without proper equipment/tools unplug wires/switches/alarms/over temps/oil level, etc. to make a dual alarm buzzer quit beeping to find the problem! Then, after setting lots of codes in the man's computor/ECUp (which is what will happen) if the beep beet still happens, look for a bad wire!.... Be for real! You don't really think I will agree with that process do you? That type of advice is kinda like telling someone, "when you have a flat, take the other three tires off so the car will sit level". But, that is just my advice! I'll stand by my bet, go to 8's house with my laptop and fix the boat. BTW, these kinda post are fun. No harm intended Evil Ghost.

I am with CAT on this one - I would not know where to begin. CAT,I will take your bet and hope to lose, but I have to be in Bham until Friday evening. What does your schedule look like next week? I was at the gym when you called and I will call you tomorrow to add some facts that I did not want to put on the board.

i am available at Lake Martin only Thursday. Email me and and let me know what to do. I think I'm gonna ride the River on Sunday. Thursday, I really don't have a lot to do, and would love to post the results of this bet! Let's see what we can figure out. Is the boat at your house? Marina? I look foreward to you call. Meanwhile, don't unplug any wires please. (Kidding of course, it's your boat and you can do what you want with it).

yes the ecu will take a reading when the switches are disconnected. and will store the code in its memory until cleared. or it will selfdestruct in 10 seconds. Regards.
