The inside of the stove below the ash pan is wet, so I assume it is internal rather than external. We started to have problems with leaks in the engine room, there was a nasty smell from the overflow tank (I think that's what it is called). We discovered it was almost empty and a leak had opened up above the water tank in the engine room. It was at this time we suddenly discovered water inside the stove at the front of the boat.

Would it be safe to use the stove (I'M FREEZING.....) or would this make the back boiler situation worse.
