Hi:I have a '96 Carolina Classic with twic Volvo KAD 42's. Recently, my left port engine is running hotter than my starboard engine. In fact, when run over 3200 RPMs, the port engine goes over the magical 200 degree mark and the temp alarm sounds.Backing down the port engine to 3000 RPMs or less returns it to a "high-normal" operating range.I pulled the strainer from the port seacock, and sure enough I found a wad of polyester line caught in the filter. I cleaned the strainer, put it back, and thought the problem would be solved - NOT!This is where I need help. The engine continues to run hot. Is there another seawater intake strainer on the engine itself that I'm missing that could be possibly clogged?? Could fibers from the line have broken through the filter and clogged some sort of water injector, if such a thing exists??Any help or advice in diagnosing the problem would be greatly appreciated!!Thx!
