Bossi, if I had to guess,.. your power steering cooler has a broken
tube. -Topher Bossi wrote: Please Help! I am leaking antifreeze from stern drive inlet, I have a closed cooling system, antifreeze drips out through propeller shaft. |

Check your heat exchanger.

Check exhaust elbow and reservoir. Especially exhaust manifold gasket and
surfaces. Look for anti freeze residue. Jim "Bossi" wrote in message oups.com... Jim wrote: Check your heat exchanger. Jim "Bossi" wrote in message oups.com... Please Help!

In a case like this I would pressure check the closed loop system with
a gauge. Have you pulled the spark plugs and checked for signs of antifreeze in a cylinder? ~Chris |
