I am not sure where you got that about being able to stand 180 degree water. My diesel truck runs the coolant at just above 180. Wrap your hand around one of the coolant hoses and see how long you can keep it there. I'm kidding, of course. You would burn yourself. Don't even try it. It is only 32 degrees from the boiling point. You can cook pasta or eggs in 180 degree water. Put your oven at 180 and stick a dish in it for a little while then try to take it out without an oven mitt if you want proof but don't do it with the grandkids around unless you want them to learn some new words to take to school.

Mainly because if you have to ask, you don't know your exhaust system well enough to mess with it. <G> However, the idea has some merit in a limited sense. For example, on my boat I have an anti-siphon loop between the heat exchanger and the exhaust riser elbow. I think that's required by ABYC, but could be wrong. Anyway, the top of that loop has a ball valve to a hose that dumps overboard. The idea is to take excess raw water and dump it overboard before it gets to the exhaust system, to reduce back pressure on the diesel. A human hand can really only stand temps below 180F, so if you can hold your hand on the metal of the exhaust riser at the point where it meets the exhaust hose, and leave it there without saying 'ouch' then the exhaust is about 180F and shouldn't melt your hoses or water lift muffler. I dump a heck of a lot of water overboard before it gets to the exhaust, and that's probably good given the length of the hose run from engine to stern. But, really, that water is *hot* coming from the engine. So you'd need to add one of those fancy cockpit shower faucets to mix hot and cold, and the cold would be coming from your tank unless you add another cold water input somewhere with a separate pressure pump. Then there would be a whole lot of plumbing and valves to deal with, to bypass the shower when not taking a shower. Frankly, it would be easier, safer, and less expensive to soap off and jump overboard. I don't know what your water temps are like... Maybe you could hang six or seven Sun Showers in series...
