    I'm looking specifically for anything that covers the alarm system. Starting up the engines this year I received an alarm on my stbd engine. It took approx 30 seconds for the audible alarm to sound and checking the gauges my temp and oil pressure are normal. After checking the engine after warm up and convincing myself all was ok I ran to our dock for approx an hour without any problems. If I could have found the noise maker it would have been re-attached to the keel. This, where ever it is, is either getting a signal from somewhere or has a defective board. Any suggestions anyone, many thanks....

    I just happened to look at another post of yours in reference to the alarm on the starboard engine. Mine would come on, we would prepare to leave the slip, the engine would cut off completely. Once I turned the key to the off position and on again lt woul start back up with no alarm. Did you ever find the source?

    Those alarms are usually close to the helm so you can hear them.
    I don’t have the diagram you’re looking for but if I remember correctly the alarms on my 87 300 Sundancer we’re behind the dash gauges.
