I acquired a 1983 Ocean Yachts Sunliner 46. The only documents on board were some general sales material from the period. Nothing covered the systems on the boat itself. Most things I can handle, but I am going crazy trying to find the heat pump/Air conditioning heating, thru-hull inlet valve, the sea strainer, seawater pump and the compressor units. I have asked around the marinas and no one knows anything about the boats, even the Ocean Yachts 46 Super Sport fishing boats. Where is the A/C thru-hull and inlet valve, sea water strainer, seawater pump and three units? I know where the three units are in the ceiling and walls, it is the other units that I cannot find. Also, I am trying to find the fresh water pump. Any idea where that is? I have found the other systems and am dealing with those.
