Danny — I’m not sure why they disconnected all of that; but given the high coolant temps, I would definitely replace all of the nylon-reinforced hose with high-temp rated hose. I’ve seen the clear hose develop “aneurisms” when under high temp and pressure; these will burst and you’ll lose all your coolant.
Having said that, it’s nice to be able to see coolant flow, which the black high-temp hose doesn’t allow. In doing a quick search, it appears that there is now silicone high-temp (500F) hose available. This might be a nice option if you want to see the coolant flow. I don’t have any personal experience with this hose. — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( > On May 2, 2017, at 10:56 AM, Danny Haughey via CnC-List > <cnc-list@cnc-list.com> wrote: > > Hello all, > > Well, In the fall of 2015, when we were in the process of buying our boat, > the water heater was hooked up and tripping the shore power breaker at the > survey.
