This is great. Sounds like it might have come from many hours of headaches as well, but I'm sure glad you shared your thoughts.
The cooling system does not have a closed loop. The water circulating is freshwater, and doesn't contain antifreeze.
The boat is a 1970 35 footer that is beautiful. If I had a digital camera I'd be posting pictures, but technology isn't my strong suit.
It will take me a couple days to get a new impellar, but once I do I'll let you know if it worked. My marine mechanic said in the mean time flip it over to see if you can pull any water. What do you think?
Also, your question about the checking valve to the seawater really concerns me. When I got the boat I hooked it up to city water, and now I wonder did I put the lever back down? I'd hate to admit to something like that.
Thanks,
