2021 Mercury pro xs 115hp 4-stroke is leaking water from freshwater flush port when engine is running. I’ve been told that the problem is probably debris in check valve. Tried flushing a few times but still leaks. Can I damage motor even if it’s still “peeing” a solid stream from indicator? Can a do it yourselfer fix this problem?
