Likely a faulty sensor.

Re: overheat buzzer will not stop

Since you mentioned the red plug, that was last used in the 1995 models all the way back to 1973. 

I would assume that you have a VRO tank in the boat and those '95 and earlier ones had electronics for the LOW OIL alarm built in to the tank pickup assembly. Then they went bad, they could give off a steady horn sound, a chirp or a warble, or a very weak buzzing sound.

If your do have the oil tank it the boat, disconnect it at the motor - 2 wires - and then see if the sound goes away.

Re: overheat buzzer will not stop

If the oil tank is still in the boat, trace the wire to see if it was left connected to the motor

How about the VRO? Is it still connected, if so disconnect it. Without VRO oiling the only alarm left is overheating.

 

Could also be a short in wiring or faulty alarm.

Did you disconnect  only 1 temperature switch or did you disconnect both temp switches? there is one on each cylinder head - tan wires

 

 

Have you checked the vacuum switch and wiring?
