In all honesty, I'll have to check if mine has an exchanger inlets when I
get up to the boat. It's a six gallon unit, and I didn't think it did.
I know my dad's 6 gallon system is not hooked in either. Whether his
tank has the capacity to run off the engine, I don't know.

Do alot of power boats in the 40' in under range in your area use the
engine? Many of the ones I've seen in the great lakes region did not.

Can you even buy an electric marine hot water heater that isn't pre-plumbed
with a heating coil?

In cases where such a heater is installed in a boat that doesn't have a closed
cooling system, I usually see the fittings for the coil capped off.

I have seen some household type water heaters stuffed into the bilges of
Cruise-a-homes and outboard powered boats with shorepower conections. The vast
majority of time they rot out very prematurely.
