Hi All,I have a new (to me) 1980 Hunter 27 with an 8HP Renault diesel. Following no apparent pattern, the engine stops passing cooling water. For example, on the way out last Sunday (my first real sail) it ran fine for 1/2 hour with the needle pegged in the cold (120 degree) position. Several hours later when I started it up again to head back in, the engine overheated and I could tell by the sound that no water was coming out the exhaust. I pulled the water pump outlet line and it was putting out water OK, but nothing coming out of the engine! The engine has two paths to the exhaust, one thru the block and a second path that appears to be some kind of by-pass. There doesn't appear to be a thermostat of any kind.I have previously backflushed the engine and examined the water pump impeller, which is fine. I backflushed it again last night, and it ran cool as could be. I have no doubt that it's going to overheat again as it's happened multiple times.Wazzup wit dat?Would appreciate any and all comments/suggestions that don't involve pulling the engine and throwing it over the rail. (I have back problems and couldn't lift it).
