My port 200 hp Mercury EFI's Ignition is beeping steadily at planning RPMs. It doesen't beep in neutral (even when revved up to 3500 rpms) or in idle gear. The engine is a 1999 and has just started doing this. I took it into a local shop after I began hearing the noise and they replaced the water pump and the thermostat on the engine at my request, which might have been a waste of money.. The motor is running strong and is using oil and is pissing water. It is not sluggish and starts right up. The beeping is coming from an alarm that is connected to the iginition switch and not the motor istelf. Any ideas??? I was going to run offshore this Saturday but am now a little afraid. The shop said the motor ran strong and everything checked out alright. I think they thought the beep was my electronics. They did river test the boat as well. Is there a short in the alarm??? Do they go bad??? I am not sure what the next step is. I know the alarm is there for a reason but I am stummped. Any help is much appreciated!!! <br /> CMB <br /><br />I have read the other posts on the same subject but still need help. The oil resevoir under the cowling is full and both of my tachometers work fine. Any ideas????? I will check the water filter and see about that possibility. My starboard motor is running fine with no beep in its ignition. Also, both engines are fed from the same tank of gas.
