I have a 1982 2GM, raw water cooled. I am not suggesting it is worth converting, but I do question the comment about requiring a different exhaust. Perhaps I am missing something, but if one were to add a 2nd pump, then one pump would circulate "fresh" water / antifeeze through one side of the heat exhanger and engine block, and the other would bring salt water in from the throughhull, through the other side of the heat exhanger and then could this not then go to the same mixing elbow / exhaust that is currently used ??
Please feel free to school me, if I have missed something.
