i took the boat out today and both engines purred on the way out of the marina until i throttled them up when the port engine started to sputter and pop out of the carb and the starboard motor ran really rough. i was able to make it back to the slip and both engines were running really rough when the port stalled. i had a buddy crank it for me while i checked it out and it would not start, just pop and sputter and i noticed the battery for that engine started to smoke at the positive terminal and was burning hot. is it possible that a bad battery or a bad cable could cause this condition to both engines? i had the same problem on my last trip last year with the boat and when the engines cooled they started right up and purred like a kitten.
