1993 mercury 60 hp beeping problem (really)

[D.D.E.]

Thanks everyone, I have several reply's and will get to work checking and trying the suggestions. This is a great site, and good people willing to help.
Thanks again, Dennis

UPDATE;
I disconnected one of the blue wires for float in injector oil tank. beeps stopped.
Tack did not start working again, and i am still wondering why the key would not shut the engine down a couple times.

I ran a direct ground wire from battery to shift, throttle control. no luck.

Thanks, Gradyfish; I am a rookie, this is my first boat, I do not know what the PM stands for, please explain.

Took it to the lake off Catawba, today, things have got to get better from here on, but we did not have to be towed and didnt get wet . i will count this as a good day, even if my son and i didnt catch anything.

Thanks Dennis
