I have a 2000 38 DA with twin 7.4 horizons with closed cooling. I am getting water in the exhaust. I have taken the complete manifold, riser and elbow from the starboard engine and placed it on the port engine. after running the engine for 5 minutes ate the dock, the water fills into #5, then over to #7 in the bottom of the runners. I started the engine cold and felt the bottom of the exhaust manifold, the part with no water jacket around it and can almost instantly tell that #5 is cooler than the others as the engine comes up to temperature. This shows that the water is cooling down the manifold. Has anyone else had this problem? I have seen the other thread on water ingestion on the 310 models and looks to be muffler related. Any help would be appreciated.
