I am losing about a half of gallon of antifreeze after

Customer Question

I am losing about a half of gallon of antifreeze after running for about an hour. the boat is not over heating under way about 22 knots but once I idle down the alarm.
Have had the system pressure tested and replaced the exhaust manifold gaskets but it is still accruing any idea what to do next.
JA: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Is there anything else the Marine Mechanic should be aware of?
Customer: I have all my engine work done by a certified Mercuiser mechanic but we are both scratching our heads since there is on antifreeze in the oil and I compression in all cinders are good.
