Interestingly, when we took possession of our '94 37/40+, the water heater was
also bypassed. The hoses were still connected, but a section had been cut out
to make the loop. As a check, I flushed the hoses with clean water (there was
actually still antifreeze in them which gave me comfort that the heater was
probably not leaking), and then plugged one end with my finger and blew heavily
into the other end. Not a proper pressure check by any means, but it was
enough to give me some confidence.
Then, I filled the heater with antifreeze & water mix as a stop-gap until I
could get around to fully flushing the engine and replacing the antifreeze.
It's working great.
I agree that the clear hose is not a good substitute for proper heater hose.

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.

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.
Surveyor said, it's probably just the element.
There is a loop in the engine for the piping to the coil heat exchanger inside
the water heater. This was hooked at inspection. Well, as i needed some
repairs done for the delivery home, I hired the yard where she spent 26 of her
30 years to fix a few things. Drain the old fuel, replace filters, replace
some gauges, repair the toilet. Well, after I got the boat home I realized
they had completely disconnected and bypassed the heat exchanger tubing from
the water heater to the engine and never said anything to me about.
I called and called and called to try and find out why but, they simply refused
to return my call.
My question now is, should i just hook it back up and see what the issue is?
Here is a pic at survey.

You can see where nylon reinforced hose is attached. Now, those two
connections are by passed. I guess I could hook up a pump and pump water
through the heat exchanger and see if anything horrible happens that way.
Then, at least, i wouldn't get antifreeze all over the place.
Anyway, any insights, advice or observations will be great appreciated!
