Hi boaters and engine operators, I am getting antifreeze back in to the water filter. Anyone have any suggestions as to what may be going on with this engine. She runs like a charm, does not overheat until the header tank appears empty??????
 
Hi bertman, i believe you have a leak at the heat exchanger mounted on back of the engine. Do not continue to run it or you may do severe damage to the engine. Remove it and have a radiator shop pressure test it. If it's bad replace it and change the zinc pencil regularly.

Hi Charlie,
We removed it and are replacing it like everything else on this old girl. Thanks, we may not have figured it out without some guidance. Bertman
