We have a 25 hsp. Mercury motor that has puzzling problem. Runs good and water discharge good. But it collects water on inside of cover. When you lift motor up water runs out where cover meets bottom part. If you take cover off water is holding in bottom part. Took cover off while running motor and couldn't see any water leaks. Thought maybe were hose goes through bottom part so hubby put clamp on it. Not the problem. Puzzling since we couldn't see anything while motor running. Guess I will take it to shop next week. They will be busy at boat show now. Has anyone else had this problem.
