My Starboard kill switch suddenly kills both engines! In the cabin but not on the fly bridge. What's happening?

Sure sounds like a short somewhere...trace and check the wiring, clean the connectors with contact cleaner spray. Maybe some of the wiring is touching the port engine somewhere and insulation has been melted off or something? Check that the kill switches are wired correctly too. I'd assume that (like the EH-700's) the kill switches activate a solenoid that pulls a lever forward to shut the fuel flow off (on the EH-700's, it's on the port side of each engine). Look in the engine room and listen while someone pushes the starboard kill switch, and see if the solenoid on the port engine is activating when the starboard kill switch is pushed.
HTH,

I have noted in the past that some mechanics and electrical technicians take short cuts. Some of them connect both engines to a single kill switch, leaving the second kill switch as a "dummy".
Reading your message: "suddenly" refers to the fact they did work separately in the past, which obviously would discredit my theory though.
Tracing the wires from the kill switches would determine if they are separately connected or wired to the same kill switch...
Good Luck!

You have kill switches? I have a 1987 3270 and I don't. Did you or a previous owner add them or were they factory?

Only the diesels have them? And they function by killing the fuel? That does not seem ideal

Because running a diesel out of fuel often requires purging the fuel system. Maybe these diesels are different but at a repair shop I use to work at mechanics would have to tare down engines and spend hours to get them started again.
To be honest tho, i really have no clue how key off terminates a diesel engine so maybe its just on older or semi truck style engines.
