Opinion time.
I never use the water in my boat, so this year I decided to not fill the tank.
Question is: Should I bypass the recirculating engine hot water to the heater, or let it go and not worry about any damage?
And, yes, I realize I cannot turn the electric elements on.
 
Your not putting hot water from motor into the heater.
The hot water from motor is circulating into the heater.
No issue if no water in there.
If there was then you could never run your boat if you had no fresh water!

I would tape over the switch so noone accidently hits it.
My wife always hits the wrong switch when she turns on the central vac, now I make her use switch on the vac.
 
You'll have to bypass two sets of water lines, the ones to and from the engine and the ones to and from the cold water line. It's no big deal to do that. I had to bypass the cold water lines on our boat because the hot water tank is leaking and it's a PITA to pull it. I do plan on doing that, however, sometime this summer. You could also unplug the electrical connection at the tank and ziptie it out of the way. That way, even if the circuit breaker is thrown, no power will go to the tank heater, which would quickly burn out without water in the tank. Hy

Yes, I know that--separate water. :)
Good idea to tape over the switch. I may check out the AC wiring at the tank and disconnect.
BTW, the Seaward HW tank is 17 years old, and likely on it's last legs anyway.
Thanks all.
