32' aft cabin.....
Heard an odd noise from friends boat yesterday. In front of the left engine, on the floor lays a pump. There is a clear line, may 3/4" that has came off from somewhere and basically this pump was pumping air. Went to the circuit panel and flipped a breaker title "water pump". Tripping this breaker stopped the motor. The line on the other side of the pump disappears somewhere behind what looks like may be some sort of liquid storage tank that sits outboard and just in front of the eng. At this point I'm assuming that tank is a fresh water tank (which she never uses) and the loose line is suppose to be connected inline to the boats water supply? I suppose I can test this theory by putting some water in that tank and seeing if it goes through that pump. There is regular water in the sinks from the shore water. One would think....that with this line off there would be water flowing out somewhere, unless there are seperate water lines on the boat, or some sort of check valve. Hell, maybe I'm way off here. What is this water pump suppose to do and how is it activated? Does it run all of the time?
