Thanks to all for your patience. I have a 1967 CD24S 6hp. It runs good but today I changed plugs and started it up in a bucket and noticed no water or mist. Engine runs hot to touch. I suspect the impeller but don't know for sure. Is there any quick way to check it? I don't have an engine diagram so I really don't understand the route the water flows? How do I find the water line and run a wire through it? Also, the evinrude site only goes back to 68. Would the impeller kit be the same? I don't know where the water pump is either? I know I sound really stupid but I'm just not familiar with outboard engines? Thanks orren
