Saw the skipper pull the cowling off the port engine, so I wandered over. He said he lost an engine; was running along normally when it sounded like someone had stepped on a plastic water bottle, and power went to near zero. Post-mortem revealed that crankcase was ventilated 120 degrees around the front of the motor, about 1/2 - 1" swath of the cast metal punched out. I suspect a con rod either broke or came loose, but couldn't see anything amiss through the gash.
Kind of depressing way to end the day.
