I just purchased a 1989 supra saltare with a pcm 351. I brought it home and put it in the water and realized my floor had water on it after running. I immediately became concerned that I had a leak but the bilge wasn't filling. The water ran across my floor slowly starting in the front and seeping back slowly dripping into the bilge and my bilge pump would empty it. I believe that my floor line sits above the waterline which would make a leak in the hull quite difficult to have above it. My floor is also gel coated so the water runs on that under the carpet until it gets to the doghouse and other gaps it can slowly drip through into the bilge. I would guess that if it was a leak it should be filling the space between the floor and the hull not above the floor. With that said I found a silver box under the playpen in front of the observer seat on the port side. It seemed that all around it was hot water. There are two hoses that connect from the engine to it both looking like water hoses. My guess is that it is the heater vent core that may have been plumbed for hot water from the engine. I turned the spicket off on the engine that came from one of the hoses that went to the box thinking it would solve the problem. Unfortunately after taking the boat out and getting it on plane all the water started to run across the carpet and eventually into the bilge. Does anyone have any experience with this? How can I fix it or turn the water off to the box? I will attach pictures of what I am talking about. Attachment 16249Attachment 16250. All advice is appreciated!
